Advance in FCC Process Reaction Chemistry

Xu Youhao and Wang Xieqing

Strategic Study of CAE 2007, Volume 9, Issue 8,   Pages 6-14

Abstract:

Faced the stringent challenge of FCC process,  the multi-dimensional reaction structure was proposed for FCC process reaction chemistry.  The multi-dimension reaction structure mode was established on the basis of hydrocarbon reaction chemistry over acid catalyst,  but the former was different from the latter.  FCC process with multi-dimensional reaction structure has more production modes.  The multi-dimensional reaction structure was used to successfully develop MIP process aiming at maximizing iso-paraffins in cracked naphtha and MIP-CGP process aiming at cleaner gasoline and more propylene.

Keywords： catalytic cracking     reaction chemistry     catalyst     two different reaction zones     multi--dimensional reaction
