Abstract
Hydrocarbons are cracked by contacting same, at elevated temperature with a solid acid catalyst having primarily Bronsted acidity which comprises at least one catalytic metal oxide component selected from the group consisting essentially of oxides of (a) tungsten, niobium and mixtures thereof and (b) mixtures of (a) with tantalum, hafnium, chromium, titanium, zirconium and mixtures thereof, supported on pyrogenic alumina. The exceptional high temperature steam stability of these catalysts permits the use of steam in the reaction zone, if desired.
