Abstract: The present invention provides, among other things, new processes for separating and purifying C4 fractions from a crude C4 stream. Compared to prior methods, the processes of the present invention simplify the C4 separation processes, afford more possible configurations for separation and purification, and are more cost effective. The processes and systems provided herein can be used as part of a cost-effective and efficient method for synthesizing methyl tertiary-butyl ether.

Abstract: The presently disclosed subject matter relates to methods and systems for alkane dehydrogenation. In a particular non-limiting embodiment, the presently disclosed subject matter provides a system for the dehydrogenation of alkanes that includes two or more reactors configured to perform a dehydrogenation reaction of an alkane in the presence of a catalyst to produce an olefin and a catalyst regenerator, coupled to each of the two or more reactors through at least one transfer line to a regenerator, for the regeneration of spent catalyst.
