Abstract:
The present invention relates to a catalyst for use in a process for the preparation of hydrocarbons comprising cobalt and manganese and/or vanadium, supported on a carrier, wherein the cobalt:(manganese+vanadium) atomic ratio is at least 12:1. Preferably, the cobalt:(manganese+vanadium) atomic ratio is at most 1500:1. The invention further relates to a process for the preparation of hydrocarbons which comprises contacting a mixture of hydrogen and carbon monoxide at elevated temperature and pressure with a catalyst as described hereinbefore. Typically, at least part of the cobalt is present in the metallic state.
Abstract:
A process for manufacturing allylhalide from gaseous propene and a gaseous halogen comprising introducing propene into a tubular loop reactor (2) through an inlet nozzle (3); introducing gaseous halogen into the tubular loop reactor (2) through several axially spaced groups (6) of radially placed inlet openings (4); allowing the propene and the halogen to react; and removing reaction effluent from the tubular loop reactor (2) through an outlet opening (9), wherein the concentration of halogen in any reactor volume-element is maintained below 3% by mass based on the total gas mixture, and wherein the linear gas velocity of the propene exiting the inlet nozzle is at least sufficient to maintain a continuous circulation within the tubular loop reactor (2) and equipment to be used for said process.
