Two-stage riser catalytic cracking process |
摘要 |
This invention relates to a new two-stage riser catalytic cracking process, particularly to an improvement of the conventional riser reactor and reaction-regeneration system by application of a two-stage riser reactor to fulfill the aims of the concatenation of oil-vapor, catalyst in relays as result in shortening reaction time and increasing average performance of the catalyst.
