FJELD OF INVENTION
The present invention relates to a new catalytic process for the removal of one or more of the greenhouse gases, CO and CO2 from a flowing gas. The invention uses ionic substances to catalyse the formation of organic compounds with a carbon number of at least one. The invention provides a new catalytic process for the low cost removal of large volumes of carbon oxides from flowing flue gas, specific product gas, and natural gas. The invention also provides a new low cost catalytic process for the conversion of carbon oxides and methane in a natural gas containing significant quantities of carbon oxides (for example between <5% to >60% C02) to organic compounds. This new catalytic process is designed to be able to remove carbon oxides from gases flowing at rates of between less than m3 per day and more than 100,000,000 m3 per day.
BACKGROUND TO THE INVENTION
There is a requirement for a process which allows the greenhouse gases (methane, carbon monoxide, carbon dioxide) to be removed directly from flowing flue gases (for example, flue or exhaust or product gases produced by combustion processes, distillation, heating, pyrolysis, carbonisation, chemical processes, separation processes or biological processes), or specific product gases, (for example, synthesis gas, or water gas, or producer gas, or town gas) or natural gas (for example, a gas containing a high nitrogen content or a high carbon dioxide content) or gases containing conventional catalyst poisons or corrosive chemicals (for example, a high sulphur content or a high chlorine content), or a combination thereof. Gases from these sources are typically available at temperatures of between -50°C and 650° C and at pressures of between atmospheric pressure and 100 bar. There is also a requirement for a process and catalyst which is able to convert the greenhouse gases CO and CO2 contained in a gas to products when the gas is delivered to the reactor at a temperature of less than 6500 C and a pressure of less than 100 bar.
The prior art (e.g. Storch et al, 1951; Sheldon, 1983, .34 US Patent 7,361,626; WO/2003/090925) has established that some metals (e.g. Co, Fe, Ni), following reduction in carbon monoxide or hydrogen or a combination thereof, to a pure metal form or a polynuclear carbide structure (e.g. Fe5C(CO)15), can catalyse the conversion of carbon monoxide and carbon dioxide in the presence of hydrogen to alkanes, alkenes, alcohols and various carbonyls at temperatures of between 180°C -450° C and pressures of between I ->30 bar. Commercial plants currently operate at temperatures of between 220°C -450° C and pressures of between 2.5 -4.5 MPa using catalysts based on reduced Fe or Co (e.g. Kreith et at, 2004, page 7-42). This prior art considers that many of the constituents of the ionic catalysts used in this invention such as sodium salts (e.g. WO/20031090925), ammonia/ammoniumlnitrates/cyanides (e.g. US Patent 2,526,651,4,549,396), halides/halogens (e.g. chlorides (Storch et al, 1951 p. 256;Higman and van der Burgt, 2008, p.66,236; US Patent 2,526,651)), sulphur containing chemicals (e.g. Storch et al, 1951, p.312-315; Higman and van der Burgt, 2008, p. 15, 233; US Patent 6,682,711; 7,192,987, 7,396,972; EP 1920836 Al)), phosphorous/phosphates/phosphines (US Patent 4,377,503; 4,539,334; 4,704,495), potassium sulphate (e.g. Storch et al, 1951, p. 226), carbonyls (e.g. US Patent 2,526,651), thiophene (US Patent 2,526,651), oxygen (e.g. Higman and van der Burgt, 2008, p. 237), arsenic (e.g. [-ligman and van der Burgt, 2008, p.243), charcoal (e.g. US Patent 7,396,798), and ionic forms of chlorine, bromine and sulphur (US Patent 6,716,886) are Fisher-Tropsch catalyst poisons. The prior art requires that the feed gas (CO + C0H + H2) should be purified to remove sulphur compounds, nitrogen compounds, particulate matter, other condensables and other catalyst poisons prior to the gas passing through the catalyst (e.g. US Patent 7,192,987; 7,396,972).
Unlike the prior art, the current invention is able to use halides and other ionic substances in the reactor to produce organic products from gases containing carbon dioxide and does not require the catalyst to be reduced in CO or H2 prior to use.
It has also been established (e.g. US Patent 1,924,762; 1,924,769; 2,135,453) that the formation of specific carboxylic acids, esters and alcohols can be undertaken at pressures of 25 -900 atmospheres (about 25 to 912 bar) and temperatures of 100° C to 400° C from a mixture of steam and CO, using the halides of Li, Na, K, Cs, Ca, Ru, Nb, Hf, Zr, Sb, Sr, Mg, Ba, Sn, Fe, Co, Ni, Bi, Mn, Mo, Pb, Te, W, V, Cr, Ta, P, Si, S, Zn, Cd supported on charcoal, Fullers Earth or kieselguhr (i.e. diatomite), or from a mixture of CO and H2 using Zn, Cu, Pb and Cd sulphides and mixtures of these sulphides with a chromium oxide (e.g. French Patent 689,342). Unlike the prior art, this invention is able to produce carboxylic acids, esters, alcohols and other organic chemicals using one or more ionic substances, without requiring the presence of H20 in the feed gas, is able to use CO2 or a mixture of CO and C02, or CO to produce the products and is able to operate over wider temperature and pressure ranges including being able to produce products at atmospheric pressures and temperatures of less than 100°C.
US Patent 6,774,149 B1 and US Patent 6,987,134 Bi claim that when NaCl is mixed with a Fischer Tropsch catalyst and operated at a pressure of 2300 -3500 psi (about 158 -241 Bar), then the Fisher Tropsch catalyst uses the carbon and hydrogen to produce the hydrocarbon while the NaCI prevents oxidation of the Fischer Tropsch catalyst by removing water. Application 2004/0002622 Al claims that when NaCI is mixed with a FeO-iron catalyst and solid organic waste in a batch reactor operated in the absence of oxygen in a stream of hydrogen at a temperature of 400° C and a pressure of 1850 psi (about 127 bar) that the NaCI prevents oxidation of the FeO catalyst by removing water. Unlike the prior art and contrary to the teachings of US Patents 6,774,149 B 1; 6,987,134 B 1; 2,526,651; US Patent Application 2004/0002622 Al this invention found that when a continuous flow of feed gas containing carbon oxides was passed through NaCI at atmospheric pressure that the carbon oxides were converted to products.
The current requirement to reduce greenhouse gas emissions (CO2 + CH4) from flue gases has created a need for a low cost, low energy requirement, small footprint, catalytic process which can convert one or more of the carbon oxides (CO + C02) contained in a feed gas into products without requiring the feed gas to be processed into a purified synthesis gas prior to use and without requiring the catalysts to be reduced in either CO or hydrogen prior to use. This invention meets these requirements and provides a low cost, low energy requirement, alternative to the current technologies.

Different catalysts or types of catalyst within the catalyst bed can have the same or different particle sizes or a combination thereof. In a fluidised bed reactor or slurry reactor or bubble reactor containing particles and liquids, some or all of the particles may fluidise when the feed gas flow rate exceeds the minimum fluidising velocity. The catalyst bed can be structured to (i) allow the particles to remain static, or (ii) allow macropores or natural pipes to develop within the catalyst bed, or (iii) allow expansion of the porosity of the catalyst bed where the particles act as moving "stationary particulates", where the downward gravitational force acting on the particles is matched by the "upward force" applied by the feed gas, or (iv) allow expansion of the porosity of the catalyst bed and the development of a "conveyor within the reactor" where the force associated with the flowing gas carries a stream of particles within the feed gas until the flow rate of the gas drops, resulting in a settling of the particles. In a vertical or inclined tubular reactor structure gravitational forces return the settling particles to the catalyst bed. In some embodiments the particles will be collected outside the reactor and may be returned to the catalyst bed by mechanical or gravitational forces or by some other method, or (v) a combination thereof Physical Processes: A physical process is any process which is used to formulate a catalyst before it is entered into the reactor which does not involve a chemical reaction. A chemical reaction results in the formation of a new covalent chemical. Physical processes include all processes designed to 1. create hydrated structures, crystals, solutions, solutes, precipitation from a solution, condensation from a gas, changes in substance phase (liquid, gas, solid), changes in substance viscosity, plasticity, liquid limit.

Physical mixing which results in the temporary or permanent exchange of anions or cations between one or more ionic substances and one or more types of solid material, or between ionic substances or a combination thereof is defined here as a physical process. Both hydration and dehydration are defined as physical processes.

BRIEF DESCRIPTION OF TABLES
The tables (Tables Ito 30) provide compositional data pertaining to 100 moles of feed gas and 100 moles of product gas for the non-limiting example (catalysts A to 0).
DESCRIPTION OF THE INVENTION
The invention comprises a process and an associated group of ionic catalysts where the ionic catalyst removes all or part of one or more of carbon dioxide and carbon monoxide contained in a flowing gas by converting one or more of carbon dioxide and carbon monoxide into products. The flowing gas includes one or more carbon containing gases (selected from CO and C02) and one or more hydrogen containing gases (selected from H2, gaseous hydrocarbons and organic chemicals). The products are organic chemicals containing one or more carbon atoms. The process removes carbon oxides from the feed gas by one or more of methanation, carbon oxide insertion, polyaddition and hydrogenation.
Products include, but are not limited to, one or more of alkanes, atkenes, alkynes, aldehydes, ketones, alcohols, arenes, amines, amides, ethers, esters, carbonyls, nitriles, carboxylic acids, aromatics, cyclic organic compounds, vinyl monomers, vinyl polymers, polymers, copolymers, addition polymers, condensation polymers, polyamides, organic halogen compounds, organic compounds containing sulphur, organic compounds containing phosphorous, organic compounds containing nitrogen, organic compounds containing a metal. The overall catalytic process results in one mole of feed gas producing less than one mole of product gas (including unreacted feed gas).
Catalyst This invention uses ionic solids or ionic liquids or ionic gases or a combination thereof, to catalyse the conversion of one or more of carbon monoxide and carbon dioxide to products. This is demonstrated in the examples described by Tables I to 30 and Figures 1 to 82 at atmospheric pressure and a temperature of 16° C -35° C. The ionic solids, ionic liquids and ionic gases can contain I12O and include one or more ionic forms of metals, carbon, hydrogen, halogens, nitrogen, phosphorous, and sulphur. This invention achieves the conversion without first reducing the catalyst in l2 or reducing the catalyst in CO to manufacture a polynuclear carbide structure (e.g. Fe5C(CO)15). This invention can use gases which have not been purified.
The use of ionic catalysts for the purpose of removing one or more of carbon dioxide and carbon monoxide contained in a flowing gas, for example, a flue gas, an exhaust gas, a waste gas, a process gas, or natural gas, by converting one or more of carbon dioxide and carbon monoxide into products using an ionic catalyst is novel and contrary to the prior art. It involves an inventive step, does not form part of the current state of the art (e.g. Storch et al, 1951; Sheldon, 1983) and is designed specifically for industrial applications.
Ionic Processes used in the Catalytic Reaction The ionic catalyst uses a process of one or more of hydrogenation, carbon oxide insertion, methanation and polyaddition to convert CO, CO2 and CH4 to organic chemicals. Examples of ionic relationships for the hydrogenation of C02, CO and CH4 used in the invention include:-CO2+e=CO2 (1) 2C02 + 2& CO + CO32 (2) 2C02 + 2H + 2e H2C204 (3) CO2 + 2H + 2e HCOOH (4) CO2+2H+2e=CO+H2O (5) CO2 + 4H + 4e HCHO + H20 (6) CO2 + 6H4 + 6e = CH3OH + H20 (7) CO2+8l-['+8eCH4+2fl2O (8) CO2 + 7l{ = CH3 + 2H20 (9) CO2 + 6H = CH22 + 2H20 (10) CO2+5H=CH3+2I-f2O (11) CO2+4H=C4+21-I2O (12) CH4=CH3+J-1 (13) Cl-L4=CH22+2j-I (14) CH4=CH3+3H (15) (16) CO+5H=CH3+l-I2O (17) CO+41{F=CH22+H20 (18) C0+3F[CH3+H2O (19) CO+2H=C4+H2O (20) 2CO+2H=H2C2O2 (21) Co + 21{' HCHO (22) Co + H20 = CO2 + 2H (23) CO + 4H4 CH3OH (24) CO + 6H4 Cl-I4 + H20 (25) 2H20 + 2& = H2 + 20H (E(V) -0.83 Volts) (26) electron; E(V) = standard reduction potential in water at 298 K (25° C); By definition (Brown et al, 2000, Table 1, p. 766), E(V) 0 volts for H2 = 2H. E(V) for Equation 26 is taken from Table 1, page 766 of Brown, L., Le May Jr, H.E., Bursten, B.E., 2000. Chemistry the Central Science. Prentice Hall, ISBN: 0-13-010310-1.
This list of equations is not inclusive and other ionic relationships occur and they are specifically incorporated.
Adsorpiton onto the Catalyst The catalyst creates an electrochemical environment within the catalyst bed which forces the carbon oxides and organic chemicals in the feed gas passing through the catalyst bed to act as weakly associated anions and cations. These anions (e.g. Equations 1 to 40) flow in a gas phase through the catalyst bed or are temporarily captured and form a loose association with the cation of the catalyst.
These anions either (a) capture the H cations (e.g. Equations I to 51) to produce a covalent organic product, or (b) capture a carbon oxide (or an organic chemical) to produce an enlarged anion, or (c) a combination thereof. The principal inorganic by-products from this ionic process are one or more of H2 and H20.
The reaction is catalysed by the ionic catalyst in the gas phase and on the catalyst surface, where chain growth from an initial organic nucleus (Equations I to 40) is by one or more of polymerisation, hydrogenation, methanation, carbon oxide insertion and polyaddition with species (reactants and products) contained within the catalyst bed (Equations 41 to 51). This is a major difference from the Fischer Tropsch and related processes which polymerises hydrocarbons (and organic chemicals) in a complex Langmuir-Hinshelwood surface reaction where the reactants are equilibrated to the reduced reaction surface prior to the reaction occurring. Polymerisation occurs in the Fischer Tropsch and related processes by (a) methylene insertion, (b) methylene insertion onto an adsorbed ethylidene, (c) carbon oxide adsorption following hydrogenation, (d) alkenyl insertion and (e) oxide bond insertion.
The principal by-products associated with the Fischer Tropsch and related processes are CO2 and H20.
The Fischer Tropsch and related processes are operated under conditions where the feed gas composition is constant, the feed gas flow rate is constant, the operating temperature is constant and the operating pressure is constant.
One application for the ionic catalyst is to remove carbon oxides from the flue gases associated with a combustion, incineration, electricity generating, or carbonisation plant. The flue gas from these sources will vary in composition, flow rate and temperature over time. The flue gas will contain oxygen when it is derived from a fuel which has been burnt in an excess of air or oxygen. The flue gas may also contain substantial quantities of nitrogen. The presence of oxygen, delivery variability, and flue gas composition variability renders this gas source unsuitable for processing using a Fischer Tropsch catalyst. This flue gas is suitable for use with an ionic catalyst as defined in this invention.
The presence of oxygen in the flue gas will poison the Fischer Tropsch catalyst by oxidising its surface.
Oxygen does not poison the ionic catalyst. The oxygen may combine with H2 or CO within the catalyst bed to produce H20 and CO2 (e.g. 02 + 2H2 2H20; 02 + 2C0 = 2CO2). Some or all of these products (CO2 + H20) will be disassociated (Equations I to 12, 26) within the catalyst bed and incorporated into organic products. Consequently, the presence of oxygen will either (a) enhance the organic product yield, or(b) increase the amount of water product or(c) alter the CO:C02 ratio of the product gas relative to the CO:C02 ratio in the feed gas or (d) a combination thereof. The Example demonstrates (Tables I to 30) that variability in feed gas composition and associated delivery parameters will be reflected in the product composition.

Similar ionic relations occur for CH and CXHYOX and these are also specifically incorporated.
Formation of Larger Covalent Organic Molecules The product can be an organic chemical containing a single carbon atom. However, the organic anion can act as a nucleus for subsequent chain growth resulting from insertion of one or more of Cl-I4, CO, C02, CI-IO, CH3, CH22, CH3, C4, H2C202, HCHO, CH3OH, I-ICOOH, H2C204 and so forth, and by polyaddition of individual nucleated chains, and by the capture of organic molecules, or a combination thereof. For example, chain growth from a nucleating centre through the insertion or addition of one or more of H2, CO, CO2 and CH4 includes, but is not limited to:-CH4-(cation + anion) + CH4 = C2H3-(cation + anion) + 2H (41) HCHO-(catjon + anion) + CH4 = CH3CHO-(cat ion + anion) + 2H (42) HCOOI-I-(catjon + anion) + CH4 CH3COOH-(cation + anion) + 2H' (43) CH3OH-(cation + anion) + Cl-I4 = CH3CH2OFJ-(catjon + anion) + 2H (44) H2C204-(catjon --anion) + CH4 CO2HCH2CO2H-(cation + anion) + 2H (45) CH4-(catjon + anion) + CO2 = CH3COOH -(cation + anion) (46) CH4-(cation + anion) + CO = CH3CHO -(cation + anion) (47) CH4-(cation + anion) + CO + 2H2 = C2H6 -(cation + anion) + H20 (48) CH.1-(cation + anion) + CO2 + 3H2 = C2H6 -(cation + anion) + 2H20 (49) This list of equations is not inclusive and other ionic relationships occur and they are specifically incorporated.
The generic reaction equation is:-aCH4 + bCO + cCO2 + dH2 + eH2O + fCXHY + gCHO = Organic chemicals. (50) a, b, c, d, e, f, g signify relative molar abundances. Each of a, b, c, d, e, f, g can be zero. Each of a, b, c, d, e, f, g can fall within the range 0 and 1. The sum ofa+ b+c + d + e + f+ g= 1.0. fCH refers to a single chemical species or a collection of different chemical species with this generic equation, for example, ethane, propane, ethene, propene, hexane, benzene, and so forth. gCHO refers to a single chemical species or a collection of different chemical species with this generic equation, for example, acetone, formaldehyde (methanal), methanol, ethanol, formic acid, acetic acid, oxalic acid, ethanoic anhydride, methyl methanoate, furan, phenol, and so forth. Products by this process can include alcohols, aldehydes, ketones, alkanes, alkenes, aromatics, carboxylic acids, esters and carbonyls. For example, for an alkane or alkene:- (n-x)C02 + (3n+a-4x)H2 + xCH4 CH2�2 + 2(n-x)H20 (51) a I for alkanes, a 0 for alkenes.
Similar equations can be constructed for the large number of aromatics and different compounds of the general form gCHO and these are specifically incorporated. The reactions described by Equations 1 to 49 and 51, and variations of these equations fall within the scope of the generic reaction described in Equation 50.
Catalyst Construction The catalysts claimed include one or more ionic solids or ionic liquids or ionic gases, or a combination thereof and are constructed from:-i) a single ionic substance (for example NaCI, KCI), where an ionic substance has one or more cations and one or more anions, or ii) a mixture of two or more ionic substances (for example NaCI plus K2S04), or iii) a mixture of one or more ionic substances with one or more non-ionic catalysts or metals or metal oxides or metal carbides or carbon or a combination thereof or iv) a mixture of one or more ionic substances with one or more types of solid material selected from one or more of organic matter, layered silicates (for example clays and micas), hydrated silicates, fullerines, ash, sulphides, silicates, ortho-silicates, ring-silicates, chain silicates, sheet silicates, framework silicates, suiphides, suiphates, carbonates, hydroxides, oxides, phosphates, halides, pyroclastic material, hydrated silicates, hydrated carbon oxides, methane hydrates, support material, macroporous, mesoporous, microporous, nano-porous material, particulate material, or v) a combination thereof of(i) to (iv) The substances referred to in (i) to (v) are mixed at atmospheric pressure and at a temperature of less than 650° C. The substances can be mixed in the presence of air or nitrogen. The ionic substance can be coated onto solid material or impregnated into solid material or a combination thereof. The substances referred to in (i) to (v) are mixed together without additional chemical processing. The mixed substances can undergo additional physical processing designed to produce a finished catalyst.
Processing can be used to impregnate or coat solid material (including support material) with the catalyst. The catalyst is not reduced in CO or H2 prior to use.
The ionic solid is anhydrous or hydrated or held in a liquid or dissolved into one or more of an aqueous solution, a polar solvent, an ionic liquid, a deep eutectic liquid, a non-polar liquid or a combination thereof. The ionic liquid is a room temperature ionic liquid or an ionic liquid with a melting point below 100° C, or a deep eutectic solvent or an ionic solid which is liquid at the reactor operating temperature or a combination thereof; the ionic liquid can be water or can be insoluble in water or can contain water or can be soluble in water or a combination thereof; the ionic liquid can be a mixture of ionic liquids or a combination of the ionic substance or ionic substances with one or more non-ionic substances or polar substances or a combination thereof. The catalyst either has no promoters or is mixed with one or more promoters selected from one or more of organic compounds, organo-rnetallic compounds, metals, metal oxides, metal sulphides, metal phosphates, metal carbonates, metal hydroxideswherethemetalsareselectedfromcjroups 1,2,3,4,5,6,7,8,9, 10,11,1213,14,15,16 and the lanthanide and actinide series of the Periodic Table. Promoters when present are added at atmospheric pressure and mixed with the catalyst at a temperature of less than 650° C. The non-limiting example (Catalysts D, E, F, and 0) includes promoters which formed part of the solid material which was mixed with the ionic substance.
The non-limiting example experiment demonstrates that (i) the presence of a micro-porous or nano-porous support can enhance catalytic activity (e.g. Catalyst F), (ii) relatively small changes in the concentration of one or more ionic compounds contained in the catalyst (e.g. Catalyst G, H) or changes in the type of support material or changes in the type of solid material can have an effect on the proportion of carbon oxides in the feed gas which are removed by the invention.
Product Suite The composition of the product suite produced by the catalyst and the conversion efficiency may change with temperature, pressure, feed gas flow rate, feed gas composition, composition of the catalyst, structure of the catalyst, reactor type, and reaction time. The product suite produced by the catalyst may change with time as the catalyst ages. The catalysts operate at a temperature of less than 650°C and pressure of less than Pa (100 bar), where a pressure of I bar equals iO Pa, and at a feed gas hourly space velocity of less than 150,000 m3 hr' per m3 catalyst.
Feed Gas Composition The feed gas contains one or more of nitrogen, nitrogenous compounds, air, oxygen, oxygen containing gases, sulphur compounds (including, but not limited to sulphides, sulphur oxides, sulphates, etc.), halogen compounds (including but not limited to halides, hydrated halogenated compounds, organic compounds containing halogens, etc.), phosphorous compounds, ammonia compounds, amine compounds, H20, acids, metal contaminants (including, but not limited to, Hg), entrained soot, entrained particulate matter, entrained solid organic chemicals, entrained inorganic matter, entrained liquid organic chemicals and entrained hydrocarbon liquids.
The non-limiting example demonstrates that the invention can be flexibly operated (i) with a nitrogen content in the feed gas of between <5% and> 70% (Figures 65, 66, 67), (ii) when carbon oxides form from <2% to >15% of a feed gas containing nitrogen, and (iii) when carbon oxides form between <2% and >50% of the feed gas constituents, excluding nitrogen, (Tables Ito 30; Figures 5 to 82). The non-limiting example demonstrates that CO removal is independent of the CO:C02 ratio in the feed gas, and that some embodiments of the invention will be able to remove CO when CO2 is absent and vice versa.
The catalytic process can be used to concentrate nitrogen in a product gas when nitrogen is a constituent in the feed gas as illustrated in the example (Figures 65, 66 and 67).
Process Constraints The non-limiting example demonstrates (Tables I to 30, Figures 1 to 82) that the invention is effective when (a) the feed gas temperature is constant or varies over time; (b) the feed gas flow rate is constant or varies over time; (c) the feed gas composition is constant or varies over time; (d) the feed gas pressure is constant or varies over time.
Reactor Required The catalyst is placed in a fixed bed reactor, membrane reactor, bubble reactor, fluidised reactor, slurry reactor, insert reactor, coated wall reactor, tube wall reactor, nano-tube reactor, micro-channel reactor, nano-channel reactor, multitubular reactor, stirred reactor, or any other type of reactor which is able to contain the catalyst. The reactor can be made from any suitable material.
The catalyst can be placed in one or more reactors. When two or more reactors are present they can be arranged in parallel or in series or a combination thereof. Each reactor may operate at the same or different gas hourly space velocities. Different reactors may contain different catalysts, or the same catalyst or variations of one or more catalyst. The catalyst composition within a single reactor may be constant or may be variable. Different catalysts or variations of the same catalyst may be placed in different parts of the same reactor or mixed together within the same catalyst bed.
The catalyst is held in the reactor as particulate material or as a coating on solid material or as impregnated solid material or as liquid or as slurry or within slurry, or a combination thereof.
Recycling all or part of the product gas into the catalyst bed may alter the proportion of carbon oxides converted to products. Recycling may result in a change in the composition of the products produced.
The process and catalyst described above will be further understood by reference to the following non-
limiting examples.
EXAMPLES
Example Apparatus
A vertical internally heated carbonisation reactor was used to generate a flue gas (the feed gas). The particulate catalyst was held in place by a porous membrane/porous sleeve in a flow line. Flow line gas composition and temperature measurements were made on the gas immediately before and after it entered the catalyst bed. The reactor and flow lines were maintained at atmospheric pressure. The feedstock used in the carbonisation reactor was a mixture of municipal waste (plastics, cardboard, paper, food waste, polystyrene packaging, etc.) and biomass (green and brown garden waste). The temperature in the combustion chamber was allowed to vary between <1500 C and >4500 C. Air was used as the oxygen containing gas. The feed gas entering the catalyst bed contained some entrained particulates.

Ionic catalyst containing promoters (Catalyst E, F, H, 0) Example Flue (Feed) Gas Composition The flue gas (feed) comprises N2 + CO + CO2 + CH4 where CH4 comprises aCH4 + dH2 + eH2O + + gCHO (Equation 50). The molar proportions of CO, C02, CH4, and N2 per 100 moles flue gas are provided in Figures Ito 4,65, 66, and 67 and Tables 1, 3,5, 7,9, 11, 13, 15, 17, 19, 21, 23, 25, 27 and 29. The CO:CO2 ratio in the flue gas is a function of combustion temperature and organic feedstock type (Figure 1). The CO:CH4 ratio in the feed gas (Figure 1) was between 1:100 and 10,000:1(0.01 to 10,000). The N2 range in the flue gas was between <5% and >80% (Fiure 2, 3, 4).
The feed gas flow rates entering the catalyst bed were varied between <700 ->60,000 m hr' flue gas per m3 catalyst. Feed gas temperatures entering the catalyst bed were varied between 16° C and 350 C. Example Product Gas Composition The product gas comprises unreacted feed gas + gaseous products. The molar proportions of CO and CO2 in 100 moles of product gas are provided in Figures 5 to 64 and Tables I to 30 for the 15 example catalysts, Catalyst A to 0. Figures 5, 9, 13, 17, 21, 25, 29, 33, 37,41,45,49, 53, 57, 61 show examples where the presence of the ionic catalyst has resulted in the CO2 content of 100 moles product gas being reduced to <30% of the CO2 content of 100 moles of feed gas. Figures 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58, 62 show examples where the presence of the ionic catalyst has resulted in the CO content of 100 moles product gas being reduced to <30% of the CO content of 100 moles of feed gas.
Figures 7, 11, 15, 19, 23, 27, 31, 35, 39, 43, 47, 51, 55, 59, 63 illustrate the relationship between Ratio F and Ratio B. They show that different catalysts may provide a different response to decreasing the relative proportion of carbon oxides to hydrogen containing compounds in the feed gas. Figures 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,48, 52, 56, 60, 64 illustrate the relationship between Ratio G and Ratio A. They demonstrate that some catalysts result in preferential removal of CO relative to CO2 and vice versa, and that this relationship can change as Ratio A changes.
The tabulated data for each set of measurements (Tables I to 30) illustrate that the catalyst can change one or more of the molar mean abundance, standard deviation, skewness and kurtosis of the CO and CO2 components of the product gas when compared with the feed gas.
Example CO, CO2 and CH4 Conversion The catalytic reaction results in 100 moles of feed gas producing less than 100 moles of product gas (including unreacted feed gas). In the example experiments the volume of product gas produced ranged between 40 and 99 moles product gas (including unreacted feed gas) for each 100 moles of feed gas.
This reduction in gas volume resulted in the N2 concentration in the product gas increasing relative to the N2 concentration in the feed gas (Figures 65, 66, 67). Each catalyst provided a value for Ratio J and Ratio K (see Figures 68 -82) which was between 0% and 100%. The non-limiting examples (Figures 68-82) identif,' that, typically, between <10% and >80% of the (bCO + cCO2) and (aCI-L1 + dH2 + eH2O + fCXHY + gCHO) was removed from the feed gas during the catalytic reaction (Equation 50).
Figures 5 to 82 demonstrate that catalysts can be constructed by mixing ionic substances or mixing ionic substances with other materials. The conversion of CO2 to products resulted in the global warming potential of the product gas being less than the global warming potential of the feed gas (where the global warming potential of CO2 and CH4 is defined on pages 14-34 and 14-35 of CRC Handbook of Chemistry and Physics, 2008-2009, 89th Edition, dated 2008, Lide, D.R. (editor) published by CRC Press, Taylor and Francis Group, ISBN-l3 978-1-4200-6679-I).
