Abstract
An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions while at the same elevation inside a riser. Multiple distributors may be used to position the tips for injecting feedstock at multiple radial positions. The distributors with tips more deeply positioned in the riser will penetrate a dense catalyst column we discovered generates in risers of larger diameter over 1.3 meters.
