Process for the preparation of hydrocarbons.

摘要

A process for the preparation of hydrocarbons comprises contacting a mixture of carbon monoxide and hydrogen at elevated temperature and pressure with a catalyst in a reaction zone, which catalyst comprises a catalytically active component and a refractory oxide carrier and is in the form of particles retained in a fixed bed within the reaction zone, which particles are helical lobed particles. The catalyst particles are preferably prepared by extrusion through a suitable dieplate.
