Abstract
A process for the dehydrogenation of alkane hydrocarbons is disclosed. The process comprises contacting the alkane with a chromium-based dehydrogenation catalyst in the presence of carbon dioxide at a temperature of from about 400° C. to about 700° C., a pressure of from about 0.1 to about 10 atmospheres, wherein the alkane to carbon dioxide molar ratio is about 1:0.0001 to 1:0.045.
Claims14
A process for the dehydrogenation of isobutane comprising contacting isobutane with a chromium-based dehydrogenation catalyst which comprises 12% to 18% by weight chromium in the presence of carbon dioxide at a temperature of from about 400° C. to 700° C., a pressure of from about 0.1 to about 10 atmospheres, wherein the molar ratio of isobutane to carbon dioxide is about 1:0.0001 to 1:0.045.
