The influence of increasing vaccum residue in feedstocks on the performances and product properties of fluid catalytic cracking was investigated by using of a riserreactor pilot unit.
利用小型提升管催化裂化装置考察了提高原料掺炼量对催化裂化行为及产品主要性能的影响。
2
The flux in the riserreactor is close to plug flow, which greatly demotes the back mixing.
并且使提升管反应器的流型更加接近活塞流,进一步减少返混。
3
Thus the particle size distribution in a riserreactor should be taken into full consideration.
