介绍了超短接触反应器的工业应用及其发展现状,指出气固下行床超短接触反应是一项新的催化工艺,它将过去气固上行逆重力场运动改变成气固下行顺重力场运动,从而减少了返混、缩短停留时间,能大幅度提高轻油收率.该反应系统也比较容易实现提升管催化裂化、催化裂解装置的改造,有利于降低装置建、改造成本.

The gas-solid downer quick-contact reaction is a new catalytic process, it changes the gas-solid upward inverse gravity field motion into the gas-solid downward gravity field motion, thereby reduces the backmixing, shortens the residence time and increases yield.In this paper，applications and development of the reactor were introduced.
