PROCESS OF PRODUCING A GAS WHICH IS RICH IN CARBON MONOXIDE BY A CRACKING OF HYDROCARBONS

摘要

Gases which are rich in carbon monoxide are produced by a catalytic cracking of gaseous or vaporized hydrocarbons. A part of the hydrocarbons is combusted with an oxygen-containing gas which is added at a rate that is twice to ten times the stoichiometric oxygen demand. The combuston temepratures are between 800 DEG and 1500 DEG C. The oxygen-containing combustion gas is admixed to the preheated remainder of the hydrocarbon and a mixture is produced which is at a temperature between about 700 DEG and about 1300 DEG C. That mixture is passed through a fixed bed consisting of a granular cracking catalyst. A high-CO product gas at a temperature between about 800 DEG and about 1150 DEG C. is withdrawn from the fixed bed.
