Název v původním jazyce

Metathesis of 2-pentene over Mo and W supported mesoporous molecular sieves MCM-41 and SBA-15

Popis výsledku v původním jazyce

Molybdenum and tungsten oxides were supported on silica, MCM-22, MCM-41 and SBA-15. XRD and N-2 adsorption-desorption revealed that architecture and textural character of supports were preserved. The catalysts were investigated in transformation of 2-pentene at different reaction temperatures. MoO3/MCM-22 exhibited highest conversions with isomerization and cracking as major reactions. MoO2(acac)(2), MoO3 and WO3 supported on MCM-41 and SBA-15 showed metathesis reaction of 2-C-5 producing propylene, C-4(-) and C-6+(-) asmajor products. Catalysts based on MCM-41 exhibited higher activity and stability than SBA-15. Addition of ethylene to 2-C-5(-) increased selectivity to propylene due to metathesis of ethylene with 2-pentene.
