Study of mesoporous catalysts for conversion of 2,3-butanediol to butenes

Study of mesoporous catalysts for conversion of 2,3-butanediol to butenes
In this study, three different types of mesoporous materials (Al-MCM-48, Al-SBA-15 and hierarchical ZSM-5 (meso-ZSM-5) where mesoporosity was introduced into ZSM-5 by sodium hydroxide treatment) were loaded with ∼20wt% CuO and investigated in the conversion of 2,3-butanediol to butenes. The results showed that the introduction of mesopores on the catalysts (Al-MCM-48 and Al-SBA-15 types) could decrease the production of cracking products, especially C3 = and C5 =–C7 = by comparison to the catalyst with ∼20wt% CuO loaded on HZSM-5; meanwhile, the selectivity of C8 = from oligomerization of butenes was found to increase with increasing pore size of the catalysts. In addition, Cu/meso-ZSM-5 catalyst has a performance with similarities to both Cu/ZSM-5 catalyst and mesoporous copper catalysts (Cu/Al-MCM-48 and Cu/Al-SBA-15) since both micropores (diameter of ∼0.55nm) and mesopores (pore size of ∼23nm) exist on meso-ZSM-5. Therefore, Cu/meso-ZSM-5 showed high activity for both cracking reactions (C3 = and C5 =–C7 =) and oligomerization (C8 =).
