Catalyzed process

摘要

A transhydrogenation process for the conversion of alkanes to alkenes with high yields and extended catalyst life between regenerations comprises the pssing 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 DEG -600 DEG C.; and (d) the temperature of the catalyst is raised during the process at a rate of from 1-15 deg. C/hr. The catalyst is preferably a chromia on alumina type.
