Abstract: A process for the conversion of an alcohol mixture may include introducing into a reactor a stream including the alcohol mixture mixed with a stream including olefins having 4 carbon atoms or more. The process may include contacting the stream with a single catalyst at a temperature above 500° C. in the reactor at conditions effective to dehydrate isobutanol, forming C4+ olefins, and to catalytically crack the C4+ olefins. The single catalyst may be an acid catalyst adapted to cause both the dehydration and catalytic cracking. The process may include recovering an effluent including ethylene, propylene, and water, and fractionating the effluent.

Abstract: A process for the conversion of an alcohol mixture to make propylene may include introducing into a reactor a stream that includes the alcohol mixture. The alcohol mixture may include 20 to 100 weight percent isobutanol. The process may include contacting the stream with a single catalyst at a temperature above 450° C. in the reactor at conditions effective to dehydrate the isobutanol, forming C4+ olefins, and to catalytically crack the C4+ olefins. The single catalyst may be an acid catalyst adapted to cause both the dehydration and the catalytic cracking. The process may include recovering from the reactor an effluent that includes ethylene, propylene, water, and various hydrocarbons. The process may include fractionating the effluent to produce an ethylene stream, a propylene stream, a fraction of hydrocarbons having 4 carbon atoms or more, and water.
