Abstract
Gases which are rich in carbon monoxide are producted 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 combustion temperature are between 800.degree. and 1500.degree. C. The oxygen-containing combustion gas is admixed to the preheated remainder of the hydrocarbon and a mixture is producted which is at a temperature between about 700.degree. and about 1300.degree. 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.degree. and about 1150.degree. C. is withdrawn from the fixed bed.
