Definitions
- This invention relates to catalysts and in particular to catalysts containing cobalt which are suitable for use in hydrogenation reactions.
- Catalysts comprising cobalt on a support such as silica or alumina are known in the art for hydrogenation reactions, e.g. for the hydrogenation of aldehydes and nitriles and for the preparation of hydrocarbons from synthesis gas via the Fischer-Tropsch reaction.
- cobalt is a relatively expensive and so, to obtain the optimum activity, it is desirable that as much as possible of the cobalt present is in an active form accessible to the reactants.
- the active form of the cobalt is elemental cobalt although in the active catalyst only some, rather than all, of the cobalt is normally reduced to the elemental form.
- a useful measure is the exposed surface area of elemental cobalt per g of total cobalt present.
- total cobalt contents are expressed as parts by weight of cobalt (calculated as cobalt metal, whether the cobalt is actually present as the metal or is in a combined form, e.g. as cobalt oxides) per 100 parts by weight of the catalyst or precursor thereto.
- Cobalt catalysts on different carriers are disclosed in “Stoichiometries of H 2 and CO Adsorptions on cobalt”, Journal of Catalysis 85, pages 63-77 (1984) at page 67, table 1. From the total maximum H 2 uptake, it is possible to calculate the cobalt surface area per gram of catalyst and the cobalt surface area per gram of cobalt. It can be seen from this reference that while the cobalt surface area per gram of total cobalt ranges between 6 and 65 m 2 /g for cobalt on silica catalysts, for cobalt on transition alumina catalysts, the cobalt surface area per gram of total cobalt ranges only between 15 and 26 m 2 /g. However for some applications it is desirable to use alumina, rather than silica, as the support.
- U.S. Pat. No. 5,874,381 describes a cobalt on alumina catalyst which contains between 3 and 40% by weight of cobalt and which has a relatively high cobalt surface area of above 30 m 2 /g of total cobalt
- the dispersion of the cobalt on the carrier is important since it is the surface of the cobalt of the catalyst which is active. Therefore it is beneficial to maximise the surface area of the metal which is present so as to produce a catalyst which has a high cobalt surface area per unit mass of total cobalt. It may be expected that the dispersion of the cobalt on the catalyst would be maximised at relatively low loadings of cobalt and that, as the amount of cobalt contained in the catalyst is increased, the surface area per gram of cobalt would decrease because the cobalt becomes more difficult to disperse on the support.
- a composition having a high loading of cobalt By using a composition having a high loading of cobalt, a greater proportion of the cobalt species is available for reduction to the active elemental cobalt, even if a significant amount of the support alumina reacts with the cobalt species to form cobalt aluminate. Indeed, even if all the support alumina reacts with the cobalt species to form cobalt aluminate, a calcined catalyst precursor having a total cobalt content above about 41% by weight inevitably contains some cobalt in a form that is not so combined.
- the transition alumina has a relatively high pore volume, above 0.7 ml/g, preferably above 0.75 ml/g, then it is possible to achieve high cobalt loadings, and the resultant catalysts, upon reduction, have a relatively high cobalt surface are per gram of total cobalt.
- the transition alumina has a pore volume in the range 0.7 to 1.2 ml/g.
- compositions containing more than 40% cobalt by weight may be made which, upon reduction, have a cobalt surface area of greater than 25 m 2 /g of total cobalt
- the invention provides a catalyst or precursor thereto, comprising a cobalt species on a transition alumina support characterised in that the catalyst, or precursor, has a total cobalt content of at least 41% by weight and that, after reduction, has a cobalt surface area greater than 25 m 2 /g of total cobalt
- cobalt species is used broadly to include both elemental cobalt and cobalt in combined form, eg. as compounds such as cobalt oxides and cobalt hydroxycarbonates
- the catalyst in its reduced form is useful for catalysing hydrogenation reactions.
- the catalyst may, however, be provided as a precursor wherein the cobalt is present as one or more compounds such as oxides or hydroxy carbonates reducible to elemental cobalt
- the material may be a catalyst precursor and may be treated to reduce the cobalt compounds to metallic cobalt or the material may itself be a catalyst and used as supplied, eg. for oxidation reactions
- the cobalt surface area figures used herein apply to the material after reduction, but the invention is not limited to the provision of reduced catalyst
- compositions of the invention may be made by the procedure of the aforesaid U.S. Pat. No. 5,874,381 by utilising a transition alumina having a relatively large pore volume It will be appreciated that the use of a large pore volume alumina may also be beneficial when making products having a smaller cobalt content.
- a method of making a cobalt/alumina catalyst or precursor thereto containing 5 to 85% by weight of total cobalt comprising slurrying a transition alumina powder having a pore volume above 0.7 ml/g with an aqueous solution of a cobalt ammine complex, heating the slurry to cause the cobalt ammine complex to decompose with the deposition of an insoluble cobalt compound, filtering the solid residue from the aqueous medium, drying and, optionally calcining, the solid residue.
- the transition alumina may be of the gamma-alumina group, for example a eta-alumina or chi-alumina. These materials may be formed by calcination of aluminium hydroxides at 400 to 750° C. and generally have a BET surface area in the range 150 to 400 m 2 /g.
- the transition alumina may be of the delta-alumina group which includes the high temperature forms such as delta- and theta-aluminas which may be formed by heating a gamma group alumina to a temperature above about 800° C.
- the delta-group aluminas generally have a BET surface area in the range 50 to 150 m 2 /g.
- the transition aluminas contain less than 0.5 mole of water per mole of Al 2 O 3 , the actual amount of water depending on the temperature to which they have been heated.
- Catalysts made by the conventional impregnation route typically impregnate the support material with an aqueous solution of a cobalt salt, typically cobalt nitrate
- a cobalt salt typically cobalt nitrate
- Such solutions have a low pH and to obtain some interaction between the cobalt and support it is desirable to use a reactive alumina, especially gamma-alumina.
- the cobalt is deposited via a cobalt ammine solution, the solutions have a high pH and under such conditions it is possible to obtain adequate interaction using less reactive aluminas, for example delta-alumina.
- the less reactive aluminas such as delta-aluminas generally have a lower pore volume than the reactive gamma aluminas. Consequently it may be difficult to make catalysts based upon theta-alumina containing large amounts of cobalt. At high cobalt contents, above 50% by weight, it may therefore be desirable to employ a large pore volume gamma-alumina despite the greater reactivity of the alumina. As the cobalt loading increases, the disadvantages resulting from increased interaction between the cobalt and the reactive alumina become less significant compared to the advantages of the ability of obtaining high cobalt loadings by using high pore volume gamma-aluminas.
- the transition alumina powder generally has a surface-weighted mean diameter D[3,2] in the range 1 to 200 ⁇ m.
- D[3,2] surface-weighted mean diameter
- the term surface-weighted mean diameter D[3,2], otherwise termed the Sauter mean diameter is defined by M. Alderliesten in the paper “A Nomenclature for Mean Particle Diameters”; Anal. Proc., vol 21, May 1984, pages 167-172, and is calculated from the particle size analysis which may conveniently be effected by laser diffraction for example using a Malvern Mastersizer.
- the alumina powder has a relatively large average pore diameter as the use of such aluminas appears to give catalysts of particularly good selectivity.
- Preferred aluminas have an average pore diameter of at least 10 nm, particularly in the range 15 to 30 nm. [By the term average pore diameter we mean 4 times the pore volume as measured from the desorption branch of the nitrogen physisorption isotherm at 0.98 relative pressure divided by the BET surface area].
- cobalt compounds are deposited in the pores of the alumina, and so the average core diameter of the composition will be less than that of the alumina employed, and decreases as the proportion of cobalt increases.
- the catalysts or precursors have an average pore diameter of at least 8 nm, preferably above 15 nm and particularly in the range 15 to 25 nm
- the particle size of the compositions of the invention is essentially the same as the particle size of the transition alumina, and so the compositions of the invention generally have a surface-weighted mean diameter D[3,2] in the range 1 to 200 ⁇ m, in one embodiment preferably less than 100 ⁇ m and particularly less than 20 ⁇ m, eg. 10 ⁇ m or less, and in a second embodiment preferably in the range 50 to 150 ⁇ m
- compositions having a total cobalt content less than 30% by weight preferably have a pore volume of at least 0.5 ml/g while compositions having a total cobalt content above 30% by weight, particularly above 40% by weight, preferably have a pore volume of at least 0 3 ml/g, particularly at least 0.4 ml/g.
- the present invention also provides a particulate cobalt/transition alumina catalyst, or precursor thereto, having a total cobalt content of 5 to 85% by weight, a pore volume above 0.5 ml/g, a cobalt surface area, after reduction, of at least 25 m 2 per gram of total cobalt, and a surface-weighted mean diameter D[3,2] in the range 1 ⁇ m to 200 ⁇ m.
- the amount of cobalt species deposited within the pores may be such that the pore volume of the compositions is less than 0 3 ml/g.
- useful catalysts and precursors can be produced if the surface-weighted mean diameter D[3,2] of the alumina, and hence the precursor and/or catalyst, is relatively small, below about 20 ⁇ m
- the present invention also provides a particulate cobalt/transition alumina catalyst, or precursor thereto, having a total cobalt content greater than 40% by weight, a surface-weighted mean diameter D[3,2] below 20 ⁇ m and having, in the reduced state, a cobalt surface area greater than 25 m 2 /g of cobalt
- compositions preferably contain 41 to 85%, more preferably 45 to 75%, by weight of cobalt.
- compositions of the invention when in the reduced state, have a cobalt surface area of at least 25 m 2 /g of cobalt as measured by the H 2 chemisorption technique described herein
- cobalt surface area is greater than 30, more preferably at least 40, especially at least 60 m 2 /g.
- the cobalt surface area tends to decrease as higher loadings of cobalt are used, but we have found that when the composition contains 50 to 60% by weight total cobalt, the cobalt surface area achievable is about 80 m 2 /g or more
- the cobalt surface area is determined by H 2 chemisorption.
- the sample (about 0.5 g) is degassed and dried under vacuum at 120° C. and then reduced by heating to 425° C. at a rate of 3° C. per minute whilst hydrogen gas is passed through the sample at a flow rate of 250 ml/min for 18 hours.
- the sample is then heated under vacuum to 450° C. over 10 minutes and maintained under those conditions for 2 hours Following this pre-treatment, the chemisorption analysis is carried out at 150° C.
- V uptake of H 2 in ml/g
- A area occupied by one atom of cobalt (assumed 0 0662 nm 2 )
- compositions may be made by slurrying the transition alumina powder with the appropriate amount of an aqueous solution of a cobalt ammine complex, eg. the product of dissolving basic cobalt carbonate in a solution of ammonium carbonate in aqueous ammonium hydroxide, to give a product of the desired cobalt content.
- a cobalt ammine complex eg. the product of dissolving basic cobalt carbonate in a solution of ammonium carbonate in aqueous ammonium hydroxide, to give a product of the desired cobalt content.
- the solution of the cobalt ammine complex preferably has a pH in the range 7 to 12.
- the slurry is then heated, e.g. to a temperature in the range 60 to 110° C., to cause the cobalt ammine complex to decompose with the evolution of ammonia and carbon dioxide and to deposit an insoluble cobalt compound, e.g.
- the alumina carrying the deposited cobalt compound is then filtered from the aqueous medium and dried.
- the procedure may be repeated, ie. the dried product may be re-slurried in a solution of the cobalt ammine complex, heated, filtered and dried, if required to increase the cobalt content of the product.
- the time allocated for the precipitation of the cobalt compound is normally about 30 to 200 minutes; the precipitation is usually complete after about 60 to 80 minutes, but the heating of the slurry may be prolonged to include an ageing step. During such an ageing step, it is believed that some of the cobalt is converted to cobalt aluminate compounds by reaction with the alumina support.
- the cobalt aluminate compounds are beneficial in that they may promote adhesion between the deposited cobalt compounds and the alumina support and thereby stabilise the catalyst. However these cobalt aluminate compounds are not catalytically active and may reduce the available cobalt surface area somewhat.
- the present invention also provides a method of making a cobalt/alumina catalyst or precursor thereto containing 5 to 40% by weight of total cobalt comprising slurrying a transition alumina powder with an aqueous solution of a cobalt ammine complex, heating the slurry for a period of not more than 200 minutes to cause the cobalt ammine complex to decompose with the deposition of an insoluble cobalt compound, filtering the solid residue from the aqueous medium, drying and, optionally calcining, the solid residue
- modifiers such as other metals or compounds thereof
- This may be effected by impregnating the dried product with a solution of a compound of the desired modifier that decomposes to the oxide or elemental form upon heating.
- modifiers include alkali metals, precious metals, and transition metals such as rhenium.
- the product may be calcined in air, eg at a temperature in the range 200 to 600° C., more preferably 200 to 450° C., to decompose the deposited cobalt compound to cobalt oxide.
- the high cobalt surface area is generated.
- the deposited cobalt compound may be directly reduced, i.e. without the need for a calcination step.
- the reduction whether or not a preliminary calcination step is employed, may be effected by heating to a temperature in the range from about 200° C. to about 600° C. in the presence of hydrogen. In the reduced material it is preferred that at least 50% of the cobalt is present as metallic cobalt
- the composition may be supplied in its oxidic state, i.e. without reducing the cobalt oxides to metallic cobalt. It may be used as a catalyst in this state for eg. oxidation reactions or it may be a precursor and reduced to an active catalyst by the end-user.
- the composition may alternatively be supplied as a reduced catalyst which has been passivated, so that the cobalt metal is protected from deactivation during storage and transportation.
- the reduction may be effected in situ.
- a precursor comprising the transition alumina and the unreduced cobalt compound, e.g. oxide, possibly dispersed in a carrier, may be charged to a hydrogenation reactor with the material to be hydrogenated and the mixture heated while hydrogen is sparged through the mixture.
- the catalysts may be used for hydrogenation reactions such as the hydrogenation of olefinic compounds, e.g. waxes, nitro or nitrile compounds e.g. the conversion of nitrobenzene to aniline or the conversion of nitriles to amines. They may also be used for the hydrogenation of paraffin waxes to remove traces of unsaturation therein They may also be useful in a wide range of other reactions, for example the Fischer-Tropsch process, ie where hydrogen and carbon monoxide are reacted in the presence of the catalyst to form higher hydrocarbons This may be part of an overall process for the conversion of natural gas to petroleum compounds wherein the hydrogen/carbon monoxide gas mixture is a synthesis gas formed by steam reforming natural gas
- a 4 liter aqueous stock solution was made up with 1918 g ammonia solution (SG 0 89 30% ammonia), 198 g ammonium carbonate. 218 g basic cobalt carbonate and 1877 g demineralised water
- the alumina employed was a transition-alumina of the gamma alumina type having a surface area of about 145 m 2 /g and a pore volume of about 0 85 ml/g and having a surface-weighted mean diameter D[3,2] of 2 08 ⁇ m, supplied by Sumitomo.
- the average pore diameter was about 23 nm.
- the alumina particles and a measured amount of the stock solution were charged to a stirred vessel equipped with a condenser.
- the pH of the aqueous solution was 11.1.
- the mixture was heated to boiling while stirring and gentle boiling at about 96° C. was maintained for a period of time, during which the solution became clear after about 90 min. The total heating time is shown in the following table.
- the solid was then filtered off, washed and then dried in air at 120° C. overnight.
- the resultant catalyst precursor was then reduced by passing hydrogen through a bed of the catalyst while heating to 430° C.
- the surface-weighted mean diameter of the reduced catalyst particles was similar to that of the transition alumina employed.
- the cobalt content of the reduced catalyst was calculated from the measured cobalt content of the unreduced material and the weight difference between the unreduced material and the reduced catalyst.
- the relative amount of alumina and stock solution was varied to provide compositions having different cobalt contents.
- Example 1 A sample of the unreduced material of Example 1 produced with an alumina to cobalt weight ratio of 1.75 and a total heating time of 270 min (unreduced cobalt content 27.9% by weight) was formed into pellets which were then broken up and screened
- Example 1 A sample of the unreduced material of Example 1 produced with an alumina to cobalt weight ratio of 0 5 and a total heating time of 240 min (unreduced cobalt content 41% by weight) was formed into pellets which were then broken up and screened
- a precursor was made in accordance with the examples of U.S. Pat. No. 5,874,381 by multi-stage impregnation of trilobal extrudates of 1.2 mm length and 1 3 mm average diameter made from gamma-alumina with a cobalt ammine carbonate complex solution followed by heating to decompose the cobalt ammine carbonate.
- the precursor had a cobalt content of 15.1% and upon reduction gave a catalyst having a cobalt surface area of 79 m 2 /g total cobalt
- a precursor containing 16.7% by weight cobalt was made by one-step impregnation of trilobal extrudates as used to make Catalyst C1 with an aqueous cobalt nitrate solution followed by drying at 120° C. for 15 hours and calcination at 300° C. for 10 hours. Upon reduction the catalyst had a cobalt surface area of 28.1 m 2 /g total cobalt
- the catalyst had a cobalt surface area of 43 9 m 2 /g total cobalt.
- particles having a size in the range 0.25 to 0.42 ⁇ m were selected for testing.
- the catalysts were tested using an isothermal reactor of internal diameter 7 5 mm with a catalyst bed length of 8 cm.
- the temperature of the catalyst bed was controlled by external heating responsive to a thermocouple disposed in the middle of the catalyst bed 4 cm from the bed inlet.
- Catalysts C1, C2 and C3 gave carbon monoxide conversions of about 10, 18, and 28% respectively with the product distribution shown in the following Table 3.
- Catalysts A and B gave complete conversion of the carbon monoxide to methane showing that while the catalysts were a good methanation catalysts, they were too active for use under those conditions as Fischer-Tropsch catalysts.
- Catalyst C1 made in accordance with U.S. Pat. No. 5,874,381 has a poor activity, giving a much lower carbon monoxide conversion than either Catalysts C2 and C3.
- Catalyst C1 when tested by the same procedure but at a lower gas flow rate (about 5 liters/h), Catalyst C1 gave a carbon monoxide conversion of about 25% and a product distribution similar to that specified in Table 3 for Catalyst C2, but giving a slightly higher proportion of the higher hydrocarbons (C 13+ ) at the expense of the C 5 to C 12 hydrocarbons.
- Catalysts A and B in accordance with the invention are much more active than Catalyst C3 and gave useful product distributions. Also Catalyst B is more active than Catalyst A.
