Beta-zeolite modified by phosphorous was used to substitute 5% USY as additive to FCC model catalyst.Micro-activity tester and fixed-fluidized catalytic cracking were used to evaluate catalytic performances of model catalysts.The results showed that FCC model catalysts with beta-zeolite modified by phosphorous as additive could increase conversion (MAT index) of raw oil,reduce specific coking and olefin content,and enhance research octane number(RON) in cracking gasoline.Cracking gas analysis showed that the yield of i -butane,C 4 olefin,and overall gas increased,which has important meaning in producing more C 4 chemicals.All this illustrates that beta-zeolite modified by phosphorous is an excellent additive for FCC catalyst.
