The invention relates to a process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen, comprising the steps of:

Process for the preparation of hydrocarbons from CO and H.sub.2

Supported cobalt catalysts with specified inhomogeneous cobalt distribution over the catalyst particles (expressed as a ratio (.SIGMA.V.sub.p /.SIGMA.V.sub.c).ltoreq.0.55 are prepared by immersion of a porous carrier into a solution of a cobalt compound in such a way that a given relation between the viscosity (in cS) and Temperature (degrees K.) of the solution and the immersion time (in sec) is met. For each immersion, this relation is (log v/t.times.T).times.10.sup.4 .gtoreq.1.

Process for preparation of catalyst

A process of manufacture of a crystalline aluminum silicate is disclosed wherein the aqueous forming solution has augmented thereto both a pyridine compound and a quaternary ammonium hydroxide. The process derives a novel crystalline aluminum silicate composition of matter.

Process for the preparation of crystalline aluminum silicate compounds

Fine-crystalline silicates are separated by filtration from an aqueous mother liquor which contains at least 30% v of a water-miscible alcohol, ketone, sulphoxide or cyclic ether which, per molecule, contain at most five carbon atoms with a boiling point below 85.degree. C.
