increased units
2.Under the condition of non-hydrogen,RON number of the upgraded gasoline has been increased by 30 units with reforming and isomerizing reaction and the contents of benzene and olefin have been slightly increased. The aromatics content is less than 30%, upgraded gasoline yield is 73. 12%, LPG yield is 24.26% , dry gas and the loss are 2. 62%.
3.The Process of Producing TAME gasoline form FCC C5 fractiin and methanol with macroporous Strong acidic Cation exchange resin as catalyst is studied in the paper The effects of reaction condition on the conversion of reactive as olefins are investigated. By etherification,the research octane number of the C5 fraction is increased by 5.2 units. The TAME gasoline is an excellent high octane blending component for gasoline pool
