Abstract
The invention concerns a process for preparing a chlorine comprising catalyst by (a) providing a Fischer-Tropsch catalyst comprising titania and at least 5 weight percent cobalt; (b) impregnating the catalyst with a solution comprising chloride ions; and (c) heating the impregnated catalyst at a temperature in the range of between 100 and 500° C. for at least 5 minutes up to 2 days. The prepared catalyst preferably comprises 0.13-3 weight percent of the element chlorine. The invention further relates to the prepared catalyst and its use.
Claims8
A process for performing a Fischer-Tropsch reaction comprising the following steps:
- providing syngas to a reactor, said reactor comprising catalyst particles obtained by a process for preparing a chlorine comprising catalyst, comprising the following steps:
- (a) providing a Fischer-Tropsch catalyst comprising:
- titania
- at least 5 weight percent cobalt, calculated on the total weight of the catalyst
- in the range of between to 0.1 to 15 weight percent promoter calculated on the total weight of the catalyst, whereby the promoter comprises manganese, rhenium, Group 8-10 noble metals, or mixtures thereof;
- (b) impregnating the catalyst with one or more solutions comprising cobalt salt of chloride until the catalyst comprises 0.13-10 weight percent of the element chlorine, calculated on the total weight of the catalyst;
- (c) heating the impregnated catalyst at a temperature in the range of 100 to 350° C. for at least 5 minutes up to 2 days;
- providing the following process conditions in the reactor:
- a temperature in the range from 125 to 350° C., a pressure in the range from 5 to 150 bar absolute, and a gaseous hourly space velocity in the range from 500 to 10000 Nl/l/h;
- removing Fischer-Tropsch product from the reactor.
