Enhanced performance of the dehydrogenation by the reduction of coke formation using pre-activated co2

Abstract

The present disclosure addresses the deficiencies described above by providing systems and methods for enhancing the efficiency and yield of alkene production. The methods and systems provide for the use of activated CO2 in a dehydrogenation reactor along with an alkane stream. Through the use of the methods and systems of the invention, catalyst deactivation by coke deposition is reduced and the selectivity and efficiency of the dehydrogenation reaction is improved.

Description

technical field [0001] The present disclosure generally relates to methods for enhancing the performance of dehydrogenation reactors, particularly by reducing catalyst deactivation caused by coke deposition. Background technique [0002] Dehydrogenation of alkanes is a well-established process for the production of various useful hydrocarbon products such as isobutene for conversion to MTBE and propylene for the polymer industry. Several catalytic methods exist for the catalytic dehydrogenation of light alkanes, including Sud-Chemie Method, UOP's Method, Phillips Star TM method as well as the Snamprogetti-Yarsintez method. [0003] Dehydrogenation of alkanes by a reversible chemical reaction involves the breaking of two hydrocarbon-hydrogen bonds and the formation of hydrogen molecules and molecules containing double carbon bonds. Despite the apparent simplicity of this reaction, its industrial realization is one of the most complex chemical processes. Since dehydroge...
