Abstract
Li/MgO shows promise as catalyst for oxidative cracking of hexane. However, it suffers from low catalyst activity and slight deactivation. Aiming at higher yields of C 2–C 4 olefins during the oxidative cracking of hexane, modification of sol–gel Li/MgO with MoO 3 is reported. The influence of varying loadings of MoO 3 on performance of Li/MgO during the oxidative cracking of hexane has been studied. Catalyst with minimum MoO 3 loading (0.5 wt%) shows best yields to C 2–C 4 olefins. Promotion by MoO 3 maintains higher surface area upon calcination at T > 500 °C and improves catalyst stability significantly by minimizing surface carbonate formation.
