ABSTRACT:
A process for converting residual oil comprising vacuum bottoms in the presence of a cracking catalyst of high surface area and comprising an ultrastable zeolite is described. More particularly, a conversion process particularly contributing to producing cycle oil and gasoline boiling range products with reduced carbon deposition in combination with a relatively high regeneration temperature operation of at least 1350.degree. F. and above, and a short contact time riser hydrocarbon conversion operation contributing to reducing slurry oil product in favor of lower boiling products is described. A fluid cracking catalyst comprising a special ultrastable crystalline zeolite of high silica to alumina ratio provides hydrothermal stability of acceptable tolerance in the environment employed.
