Catalytic process for hydrogen transfer between hydrocarbons.

摘要

A transhydrogenation process for the conversion of alkanes to alkenes with high yields and extended catalyst life between regenerations comprises the passing of an alkane combined with a suitable hydrogen acceptor over a catalyst bed, subject to the conditions that
(a) the pressure is from 0-4 atmospheres (gauge);(b) the hydrogen acceptor is present to the extent of from 5-30% by volume;(c) the temperature of the catalyst is from 400° - 600°C; and(d) the temperature of the catalyst is raised during the process at a rate of from l-l5 deg. C/hr. The catalyst is preferably a chromia on alumina type.
