The process involves both cleavage and formation of C-H and C-C bonds, and usually proceeds through a sequence containing dehydrogenation of alkanes to form alkenes, alkene (olefin) metathesis, and hydrogenation of the new alkenes. Both single-site systems and tandem dual-catalytic systems have been developed to effect this process. Alkane metathesis has been applied in the transformation of medium-weight alkanes into a mixture of longer and shorter alkanes, upgrading short-chain alkanes, and for the degradation of polyethylenes.
