The catalysts with SBA-15,MCM-48,SiO2,and MTS-9 as supports were synthesized with 8%WO3,and their catalytic performance for metathesis of butene to propene were carried out.The conversion of butene is 30%~37%on the catalysts with SBA-15,MCM-48,and SiO2as supports,and that of butene is 37%~42%on WO3/MTS-9 catalyst.The catalyst characterization results show that the catalytic activities depend on the acidic numbers of catalysts prepared and the distribution of tungstens on the supports used.As a result,the performance of 8%WO3/MTS-9 catalyst for the titled reaction is best.
The catalysts with SBA-15, MCM-48, SiO2, and MTS-9 as supports were synthesized with 8% WO3, and their catalytic performance for metathesis of butene to propene were carried out. The conversion of butene is 30% -37% on the catalysts with SBA-15, MCM-48, and SiO2as supports, and that of butene is 37% ~ 42% on WO3 / MTS-9 catalyst.The catalyst characterization results show that the catalytic activities depend on the acidic numbers of catalysts prepared and the distribution of tungstens on the supports used. As a result, the performance of 8% WO3 / MTS-9 catalyst for the titled reaction is best.
