Abstract

Molybdenum and tungsten oxides were supported on silica, MCM-22, MCM-41 and SBA-15. XRD and N₂ 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-C₅⁼ producing propylene, C₄⁼ and C₆₊⁼as major products. Catalysts based on MCM-41 exhibited higher activity and stability than SBA-15. Addition of ethylene to 2-C₅⁼ increased selectivity to propylene due to metathesis of ethylene with 2-pentene.
