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.

Method for starting up a Fischer Tropsch process

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&#xb0; 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.

Method for starting up a fischer tropsch process

The present invention pertains to a reactor tube comprising a fixed bed of Fischer-Tropsch catalyst particles, wherein the catalyst particles in 5% to 40% of the fixed bed volume at the upstream end have an average outer surface to volume ratio (S/V) in the range of between 3.0 to 4.5 mm, and the catalyst particles in the remaining fixed bed volume have an average outer surface to volume ratio (S/V) in the range of between 4.5 to 8.0 mm, and wherein the difference between the average S/V of the particles at the upstream end and the average S/V of the particles in the remaining fixed bed volume is at least 0.5 mm.

Method of manufacturing a catalyst

The invention provides a process for the alkylation of an aromatics compound with a olefin alkylation agent which comprises contacting the aromatic compound, especially benzene, with the alkylation agent, especially ethylene and/or propylene, in the presence of an oxide material which is delayered MWW-type zeolitic material, very suitably the material known as ITQ-2.

Aromatics alkylation

There is provided a process for the incineration of gases containing sulphur compounds by contacting these gases with an oxygen-containing gas in the presence of a catalyst composition comprising (i) a metal selected from bismuth, molybdenum and chromium as a first metal component and (ii) at least one Group IIA metal as a second metal component, supported on a refractory oxide carrier not being a carrier comprising both aluminum and phosphorus.
