Abstract
Abstract A Fischer-Tropsch catalyst is prepared by impregnating a silica carrier with a solution of a zirconium or titanium compound, calcining the composition thus obtained, thereafter impregnating the carrier with a cobalt compound-containing solution and calcining and reducing the composition thus obtained. Catalysts so prepared and containing 5-40 pbw of cobalt and 2-150 pbw of zirconium or titanium per 100 pbw of silica, are used in the preparation of hydrocarbons from a H 2 /CO mixture.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
106 words
A process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen, characterized in that a H 2 and CO-containing feed is contacted at a temperature of 125°-350° C. and a pressure of 5-150 bar with a catalyst which contains 5-40 pbw cobalt and 2-150 pbw zirconium or titanium per 100 pbw silica and has been prepared by impregnating a silica carrier once or several times with a solution of a zirconium or titanium compound, calcining the composition thus obtained, impregnating the calcined composition once or several times with a solution of a cobalt compound and calcining and reducing the compositions thus obtained.
Claim 2
Dependent Claim
106 words
A process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen, characterized in that a H 2 and CO-containing feed is contacted at a temperature of 125°-350° C. and a pressure of 5-150 bar with a catalyst which contains 5-40 pbw cobalt and 2-150 pbw zirconium or titanium per 100 pbw silica and has been prepared by impregnating a silica carrier once or several times with a solution of a zirconium or titanium compound, calcining the composition thus obtained, impregnating the calcined composition once or several times with a solution of a cobalt compound and calcining and reducing the compositions thus obtained.
Claim 3
Dependent Claim
25 words
A process as claimed in claim 1, characterized in that the impregnation steps for the preparation of the catalyst are carried out as dry impregnation.
Claim 4
Dependent Claim
37 words
A process as claimed in claim 1, characterized in that if the deposition of zirconium or titanium and/or cobalt is carried out in more than one step the metal-containing compositions obtained are calcined after each impregnation step.
Claim 5
Dependent Claim
42 words
A process as claimed in claim 1, characterized in that the calcination of the metal-containing compositions is carried out at a temperature of 350°-700° C. and that the reduction of the metal-containing compositions is carried out at a temperature of 200°-350° C.
Claim 6
Dependent Claim
17 words
A process as claimed in claim 1, characterized in that the catalyst contains zirconium as a promoter.
Claim 7
Dependent Claim
38 words
A process as claimed in claim 1, characterized in that for depositing zirconium on the silica a solution of an organic zirconium compound in an organic solvent or mixtures of organic solvents is used as the impregnation liquid.
Claim 8
Dependent Claim
26 words
A process as claimed in claim 1, characterized in that the catalyst comprises at most 100 pbw of zirconium or titanium per 100 pbw of silica.
Claim 9
Dependent Claim
26 words
A process as claimed in claim 7, characterized in that the catalyst contains at most 20 pbw of zirconium or titanium per 100 pbw of silica.
Claim 10
Dependent Claim
26 words
A process as claimed in claim 1, characterized in that it is carried out at a temperature of 175°-275° C. and a pressure of 10-100 bar.
Claim 11
Dependent Claim
30 words
A process as claimed in claim 1, characterized in that it is applied to a H 2 and CO-containing feed having a H 2 /CO molar ratio higher than 1.75.
Claim 12
Dependent Claim
29 words
A process as claimed in claim 1, characterized in that it is used as part of a multi-step process for the conversion of a H 2 and CO-containing feed.
Claim 13
Dependent Claim
91 words
A process as claimed in claim 11, characterized in that it is used as the second step of a two-step process in which a H 2 /CO mixture is contacted in the first step with a catalyst containing one or more metal components with catalytic activity for converting a H 2 /CO mixture into hydrocarbons and/or oxygen-containing organic compounds and in which H 2 and CO present in the reaction product of the first step--optionally together with other components of that reaction product--are used as the feed for the second step.
Claim 14
Dependent Claim
74 words
A process as claimed in claim 11, characterized in that it is used as the first step of a two-step process for preparing middle distillates from a H 2 and CO-containing feed, in which at least the part of the reaction product of the first step whose initial boiling point lies above the final boiling point of the heaviest middle distillate desired as end-product is subjected in the second step to a catalytic hydrotreatment.
