Synthesis of Strong Solid Acid MoO3/ZrO2 and Application to the Alkylation of Isobutane with Butene

Abstract

Abstract: MoO₃/ZrO₂ nanoparticles were synthesized in AOT/isooctane reverse micelle system. The transmission electron microscope(TEM) results indicate that the size distribution of nanoparticles is normal and the size of more than 95% particles is between 38 and 60 nm. MoO₃/ZrO₂ particles was loaded on γ -Al₂O₃ and present a high dispersity. According to NH₃-TPD and alkylation,MoO₃/ZrO₂ particles apparently have more acid sites and higher activity than those prepared by using impregnation and sol-gel method. The yield of C₈ is about 79%.

Key words: Reverse micelles, Nanoparticles, MoO₃/ZrO₂, Strong solid acid, Isobutane/butene alkylation
