摘要：
The selectivity of the by-products' formation for the dehydrogenation of methylcyclohexane (MCH) is studied under varying conditions of temperature, pressure, and feed composition. Benzene, cyclohexane, and ring-closed products (dimethylcyclopentanes and ethylcyclopentane) were found as the major by-products. The yield of these major by-products increased with an increase in the total pressure as well increased hydrogen concentration in the feed. Analyses of benzene and cyclohexane formation reveal cyclohexane is an intermediate in the formation of benzene.
