atalytic oxidative cracking is as an alternative route to
steam cracking for the production of light alkenes. It is
combination of heterogeneous and homogeneous reactions;
where reaction is initiated on the catalyst surface via alky
radical generation followed by thermal gas phase cracking.
Various catalyst systems have been attempted in literature
for the catalytic generation of alkyl radicals at moderate
temperatures (550–650

monoliths. In
addition to catalytic initiation of radicals, alkyl generation
using non-equilibrium plasma is studied. Plasma-catalysis
in oxidative cracking induces synergy effects and introduces
significant improvement in yields of alkenes, however further
understanding of plasma chemistry needs to be elaborated.

alkenes remains the bottleneck for the commercialization
of oxidative cracking process. Future research should focus on
reactor design and on developing optimized reactor catalyst
systems. A review on various catalyst systems attempted for
oxidative cracking of light alkanes to alkenes will be presented.
