摘要: Process to separate propene from gaseous fluid catalytic cracking products by performing the following steps: a) separating a feed mixture comprising the gaseous products, propene and other saturated and unsaturated hydrocarbons obtained in a fluid catalytic cracking process into a hydrocarbon-rich liquid fraction and a hydrogen containing gaseous fraction, b) separating the hydrogen containing gaseous fraction into a hydrogen-rich gaseous fraction and a hydrocarbon-rich gaseous fraction by means of a membrane separation, c) supplying the hydrocarbon-rich gaseous fraction obtained in step (b) to an absorber section and obtaining in said absorber section a lower boiling fraction rich in gaseous products having a boiling point of ethane or below and supplying the hydrocarbon-rich liquid fraction obtained in step (a) to a stripper section and obtaining in said stripper section a higher boiling fraction comprising propene and hydrocarbons having a boiling point higher than ethane.

摘要: A method of purifying a vapour product stream obtained from cracking of biomass catalysed by a fluidised solid catalyst, the method comprising: a) separating catalyst from the vapour product stream to provide a de-catalysed vapour product stream; and b) cyclonically separating solid biomass residue from the de-catalysed vapour product stream to provide a purified vapour product stream, wherein cyclonically separating solid biomass residue comprises bringing the de-catalysed vapour product stream to a gas velocity in the range of from 35 to 80 m/s.
