PROCESS FOR THE PREPARATION OF HYDROCARBONS

摘要

In the preparation of hydrocarbons from syngas over a Co/Zr/SiO2 catalyst which has been prepared by impregnation and/or kneading, the catalyst is applied in the form of a fixed bed which meets a specified relation between its external (Se) and internal (Si) surface. In order to show a high C<+>_5 selectivity the catalyst bed should have an Se (between 5 and 70 cm<2>/ml) and an Si (between 10 and 400 m<2>/ml) such that the following relation is satisfied: 10<6> > Se<2> x Si > 2.5 x 10<4>.
