Abstract: A method of improving the uniformity of the contacting of a heavy oil feed with FCC cracking catalyst in the feed zone of an FCC cracking riser in which the heavy oil feed is injected into the catalyst in the riser by means of feed injectors located around the riser, the method comprising minimizing the differences in the temperature profile in the oil/catalyst mixture across the feed zone by varying the oil feed rate to the injectors.
