ABSTRACT:
Non-hyrogenative endothermic catalytic cracking of hydrocarbon, particularly petroleum, fractions at relatively low pressures and high temperatures in a system where the endothermic heat required for cracking is supplied by catalyst as the heat transfer medium, which catalyst has been heated by burning coke deposited on the catalyst during cracking; and wherein a decomposable compound of platinum, palladium, ruthenium, iridium, osmium, rhodium or rhenium, is introduced into contact with the cracking catalyst during said process.
