PROCESSO PARA A PREPARACAO DE HIDROCARBONETOS POR REACAO CATALITICA DE MONOXIDO DE CARBONO COM HIDROGENIO

摘要

Process for the preparation of hydrocarbons in which a mixture of carbon monoxide and hydrogen is contacted with a catalyst comprising cobalt supported on a carrier, the cobalt being distributed over the carrier in such a way as to satisfy the relation …… wherein SIGMA Vc represents the total volume of the catalyst particles under consideration and SIGMA Vp is found by totalizing the peel volumina present in the catalyst particles, when the latter is taken to be composed of a kernel surrounded by a peel, the kernel being of such a shape that at every point of the kernel perimeter the shortest distance (d) to the perimeter of the peel is the same, and that d is equal for all catalyst particles under consideration and has been chosen such that the quality of cobalt present in SIGMA Vp is 90% of the quantity of cobalt present in SIGMA Vc.
