METHOD FOR HETEROGENEOUS CATALYTIC PARTIAL DEHYDROGENATION OF HYDROCARBON TO UNDERGO DEHYDROGENATION Russian patent published in 2012 - IPC C07C5/333 C07C11/06 

FIELD: chemistry.

SUBSTANCE: method for heterogeneous catalytic partial dehydrogenation, where an input stream of a gaseous reaction mixture containing the hydrocarbon to be dehydrogenated passes through a solid catalyst layer in a column, and the input stream of the gaseous reaction mixture in the column is formed by adding a gas I to the input stream being fed to the solid catalyst layer in the column, where gas I contains molecular hydrogen and the hydrocarbon to be dehydrogenated. An input gas II containing molecular oxygen is added before the solid catalyst layer.

EFFECT: method provides completely satisfactory homogenisation of CO₂ concentration after passing through an inert layer.
