- a catalyst optionally suspended in an aqueous medium, said hydrogen is recovered from the residual liquor of said unit.
- the aqueous medium is preferably at acidic pH and may comprise stabilizers of hydrogen peroxide, surfactants, preferably fluorinated and halogenated derivatives chosen from alkali metal bromides and chlorides, hydrobromic acid, hydrobromic acid and the like. hydrochloric acid and bromine in the gaseous state or in solution in water (bromine water).
- the bromide is preferably used and advantageously in combination with bromine in the free state (Br 2 ).
- the process for the direct production of hydrogen peroxide can be carried out at a temperature of between room temperature and 60 ° C., preferably less than 45 ° C. and at a pressure greater than atmospheric pressure, preferably between 10 and 80 ° C. bars and advantageously between 20 and 50 bars.
- the process for the direct manufacture of hydrogen peroxide can be carried out continuously or batchwise in a tubular reactor, in a stirred reactor, in a membrane reactor, in a reactor with a circulation loop or in a microreactor.
- a stirred reactor When the process is carried out in a stirred reactor, preferably vertical in a cylindrical form, hydrogen and oxygen are injected in the form of small bubbles into an aqueous reaction medium made acidic by the addition of an inorganic acid .
- the stirred reactor is equipped with means for injecting gaseous reactants at the bottom, outlet means at the top to evacuate the gaseous reactants.
- the reactor is preferably provided with a plurality of centrifugal turbines arranged along a single agitating shaft. Reference may be made to the documents WO 99/41190 and WO 01/05498.
- the catalyst used is generally a supported catalyst based on at least one metal selected from the group of noble metals formed of palladium, platinum, ruthenium, rhodium, iridium, osmium, holmium and gold.
- a supported bimetallic catalyst comprising palladium and platinum is preferably used.
- the waste liquor is preferably subjected in the unit (1) to partial oxidation under pressure, preferably between 20 and 60 bar, advantageously between 30 and 50 bar, in the presence of molecular oxygen, preferably of higher purity or equal to 92% and advantageously greater than 99.5% by weight, obtained by separation of the gases from the air in the unit (7).
- the waste liquor is converted simultaneously into green liquor and synthesis gas in unit (1).
- the green liquor is recycled to the unit (2) for manufacturing and bleaching cellulosic pulps.
- the unit (1) can be fed in part or in full by other sources of biomass such as glycerol, wood or oils from the pyrolysis of the straw.
- cryogenic distillation gas permeation which uses a preferential permeability with respect to one of the constituents of the mixture to be separated through a membrane or adsorption which involves a preferential fixation of one or more constituents of the mixture on an adsorbent which is generally a zeolitic molecular sieve, but which may also be a carbon molecular sieve, or even a combination of both types.
- Hydrogen is then separated from the gaseous effluent from the partial oxidation of the unit (1), preferably comprising 25 to 45% by weight of hydrogen and 18 to 45% by weight of carbon monoxide. , from 7 to 32% by weight of carbon dioxide, from 0.5 to 2% by weight of sulfur compounds (in particular H 2 S), after possible elimination of acid gases, essentially carbon dioxide and hydrogen sulphide, in particular by chemical and / or physical absorption.
- sulfur compounds in particular H 2 S
- the absorbed gases are released by raising the temperature and lowering the pressure.
- the most used absorbents are alkanolamines (monoethanolamine: MEA, diethanolamine: DEA), alkaline salts (hydroxides of sodium or potassium).
- the acidic products are absorbed in a solvent which is regenerated by expansion.
- the most used solvents are methyl ether, propylene glycol or methanol.
- all or part of the hydrogen is purified, for example by adsorption, then possibly part or all of the hydrogen is purified by methanation to convert carbon monoxide (poison catalysts direct synthesis of peroxide of hydrogen) and residual carbon dioxide to methane.
- methanation catalysts direct synthesis of peroxide of hydrogen
- residual carbon dioxide to methane.
- only part of the hydrogen produced by the oxygenation unit is used for the production process of hydrogen peroxide. In this case it is preferred to recover by adsorption only a portion of the hydrogen contained in the synthesis gas but with high purity.
- the remainder of the hydrogen and the carbon monoxide and carbon dioxide separated in the purification unit are remixed with the main stream of synthesis gas downstream or upstream of the gas separation unit.
- the synthesis gas freed from sulfur impurities can be sent to a so-called gas-to-water conversion unit, which converts all or part of the carbon monoxide into hydrogen and dioxide. of carbon by reaction with water vapor.
- This operation has the effect of increasing hydrogen production and decreasing the concentration of carbon monoxide.
- the hydrogen-rich gas thus produced can be purified by removing the carbon dioxide present and the remaining traces of carbon monoxide by the methods described above.
- the pressure of the hydrogen after the purification step is close to the pressure used for the direct synthesis of hydrogen peroxide.
- the integrated installation according to the present invention has the advantage of being compact and thus of reducing the cost related to the investment.
- the integration on the same site of the different stages of the process eliminates for the production of hydrogen peroxide the need to invest in a unit for separating the gases from the air and in a unit for producing hydrogen by example of catalytic reforming of methane or natural gas.
- the unit for separating the gases from the air is necessary for the gasification of biomass (black liquor for example) which itself produces hydrogen under pressure.
- the integrated process according to the present invention is of interest from an environmental point of view. Indeed, on-site production eliminates the need to transport hydrogen peroxide from the production site to the consumption site. Large amounts of energy are consumed during the transport of aqueous solutions of oxygenated water because they have concentrations of between 35 and 70%, and often at concentrations of about 50% by weight, the rest being composed of water. Carrying oxygenated water is like transporting water that is not useful in downstream processes. On-site production of hydrogen peroxide therefore has a primary environmental benefit in terms of transportation-related greenhouse gas emissions.
- Another environmental advantage of the process according to the invention is linked to the greenhouse gas emissions linked to the process itself: the steam reforming of natural gas co-produces around 10 kg of CO2 per kg of hydrogen produced.
- This value can increase up to 25 kg of CO2 per kg of hydrogen when the hydrocarbon source is a heavy refinery residue.
- the CO2 emissions related to the process does not contribute to global warming because the carbon source is renewable.
- the plant, for example the tree, for its growth has pumped atmospheric CO2 and metabolized for example in the form of cellulose.
- the hydrogen peroxide produced according to the process of the invention does not contribute to global warming or contributes less to it.
- Another environmental advantage of the process is related to the absence of working solution consisting of organic solvents, since the synthesis of hydrogen peroxide is directly carried out in water. There is therefore no risk of accidental dispersion of solvents in the environment, which is particularly problematic when production sites are isolated, such as paper mills.
