TH3227B - Process for preparing hydrocarbons - Google Patents

Abstract

A process for preparing hydrocarbons where mixtures of carbon monoxide and hydrogen are in contact with the assembled catalyst. with cobalt supported on the substrate dispersed cobalt It is on the support in a relational way (chemical formula) where (chemical formula) is the volume of all catalyst particles. under consideration and (chemical formula) can be obtained by combining Shell volume in catalyst particles When you think that the cata particles A list consists of an inner seed surrounded by a husk. The inner seed has such a shape that at all points of the periphery of the seed at a distance. The shortest (d) going to the periphery of the shell is equal and that d is equal for all catalyst particles under consideration and Choose such that the amount of cobalt contained in (chemical formula) is 90% of the amount of cobalt contained in (chemical formula).

Claims (5)

1. The process for preparing hydrocarbons by reacting using a catalyst of carbon monoxide with hydrogen to contact a cat. High temperature and pressure lists Which this catlist consists of Cobalt supported on the substrate Cobalt rubbed on A correlated substrate (chemical formula) where (chemical formula) is the volume of all catalyst particles under Under consideration and (chemical formula) can be obtained by combining the volumes of The shell contained in the catalyst particles. When considering Lisst is made up of inner seeds, surrounded by the inner seed shell, shaped like that at every point of the periphery of the inner seed The shortest distance (d) to the periphery of the shell is And that d is going to be equal for all catalyst particles. Under consideration And a model was chosen that the amount of cobalt contained in (chemical formula) would be 90% of the cobalt content in (chemical formula). The catalyst was prepared by dipping a porous substrate. Prune in water for about 30 minutes and after allowing the drip to dry, dip the water-saturated substrate into the salt solution. Cobalt in water several times, each time for approximately 30 seconds after each dip Cobalt-containing substrate Stay will be made Dry and calcine 2. The process, as set forth in claim 1, characterizes that the catalyst contains silica-alumina or silica-alumina substrate. 3. The process, as held by claim 1 or 2, characterizes that the catalist is composed of 3-60 cobalt by weight per 100 parts by weight. 4. The process, as assumed in claim 3, characterizes that the catalist is composed of 5-50 parts cobalt by weight per 100 parts substrate. 5. Process for which it holds a right to one of the claims Of claims 1-4 showing the characteristics that the catalist It consists of one or more selected promotes of zirconium, titanium, crimium and ruthenium (5 claims, 2 faces, figure).
