【Abstract】 The technologies of increasing propylene yield, such as SCC,MGG and MOI are briefly introduced. For a FCC unit, by taking measures such as raising the pressure of absorber, lowering the absorbing temperature and improving the quality of makeup absorbing oil, etc.,propylene yield from liquid hydrocarbons are increased to meet the demand of the market.更多还原
