Abstract

Cracking is carried out at 650-900 degrees C in presence of a catalyst contg. (1) >=20 wt.% oxides of Be and/or Ca and/or Sr and (2) aluminium oxide sinter products as remainder. Prefd. conditions are hydrocarbon flow rates of 5,000-50,000 v./v./h. and wt. ratios of steam to carbon of 0.5-10.1. Lower olefins e.g. ethylene are obtained in higher yields at lower temps. than usual, and the catalysts operate without interruption or coking for long periods.
