Abstract
A dehydrogenative coupling process to convert alkanes to longer chain olefins in a single process step is described. The approach described combats the thermodynamics of traditional dehydrogenation by consuming the products as they form. This dehydrogenative coupling reaction may be performed in a single reactor which could enable increased per-pass yield of desirable C8+ olefins compared to a traditional two reactors in a series.
Claims16
A method comprising:
- forming a mixed bed comprising a dehydrogenation catalyst and a coupling catalyst in a ratio comprising at least 1:2;
- and
- providing a feed stream to the mixed bed causing a reaction;
- wherein:
- the forming and the providing are performed in a reactor,
- the reactor has a temperature of approximately 400° C. and a pressure of approximately 95 psig, and
- the reaction results in a higher molecular weight hydrocarbon.
