Process for the dehydrogenation of hydrocarbons

摘要

A process for dehydrogenating dehydrogenatable hydrocarbons is disclosed in which a heat providing stream is utilized to supply a portion of the endothermic heat requirement of the reaction zone feed thereby decreasing the temperature drop of the dehydrogenation zone material. As a result, the amount of deleterious side reactions such as thermal cracking is reduced, and an increase in conversion of the dehydrogenatable hydrocarbons is realized.
