Progress in Decreasing Olefins of FCC Gasoline Using Technology of FCC Gasoline Modification

The importance of decreasing olefin of FCC gasoline was discussed. Progress in technologies of decreasing olefin of FCC gasoline was introduced in detail from modification of FCC gasoline property such as hyogenization, etherification, isomerization, alcylation etc. and the same ,a kind of ionic liquid, which is a new medium for decreasing olefin in FCC gasoline was introduced.
