In the paper we study a method of increasing the yield of dehydrogenation products of methylbutenes by virtue of intermediate removal of the hydrogen formed during the dehydrogenation and partial compensation of heat losses. In the example of dehydrogenation of methylbutenes into the isoprene, the oxidation of hydrogen on the platinum catalyst [charged inside the layer of ferric potassium catalyst] for the dehydrogenation of olefins is considered.

A theoretical model of the industrial method of the compensation of thermal energy consumed on the endothermic dehydrogenation on a fixed catalyst layer has been described. The combination of endothermic dehydrogenation with interlayer (intermediate) oxidation of produced hydrogen has been considered based on the example of the dehydrogenation of isoamylenes to isoprene. The calculated results are compared with laboratory tests.

The paper shows the effect of butylenes concentration in feedstock on the process of dehydrogenation of butane into butylenes using chromia-alumina-potassium catalyst. Butylenes as contained 1 to 7 % wt. in butane slip completely without hindering the process of converting of butane.

Hydrogenation and isomerization of α-pinene on heterogeneous catalysts were studied, and conditions were found for hydrogenation of pinene to cis-pinane on nickel catalysts and for its dehydrogenation to p-cymene on decationized zeolite Y.
