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