Abstract
Official abstract text for this publication.
The invention relates to a method to start up a Fischer-Tropsch process. A catalyst with a latent activity is used. The catalyst comprises titania, cobalt, promoter, and chlorine. The catalyst comprises more than 0.7 and less than 4 weight percent of the element chlorine, calculated on the total weight of the catalyst.
First claim
Opening claim text (preview).
That which is claimed is: 1. A method to start up a Fischer-Tropsch process comprising the steps of: (a) providing a reactor with a Fischer-Tropsch catalyst that comprises: 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, whereby the promoter comprises manganese, rhenium, Group 8-10 noble metals, or mixtures thereof; and more than 0.7 and less than 4, weight percent of the element chlorine, calculated on the total weight of the catalyst, (b) providing syngas to the reactor, and (c) providing the following process conditions in the reactor: a temperature in the range from 150 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. 2. The method according to claim 1 , wherein the catalyst is fixed in the reactor. 3. The method according to claim 1 , wherein at least 25 weight % of the catalyst comprises particles having a particle size of at least 1 mm.
