Method for alcohol upgrading to jet, diesel, gasoline, and valuable co-products
Abstract
A method for converting an alcohol to a jet-diesel hydrocarbon fraction, comprising contacting the alcohol with a pillared two-dimensional zeolite catalyst at a temperature of at least 200° C. and up to 500° C. to convert the alcohol to hydrocarbons comprising: (a) a first mixed olefin fraction containing a mixture of C2-C5 olefins; (b) a first paraffin fraction containing C3-C5 paraffins; and (c) a gasoline fraction containing C6+ hydrocarbons; and the conversion of the alcohol is energy neutral or exothermic. The first mixed olefin fraction may be subjected to an oligomerization process to result in a second paraffin fraction containing C3-C6 paraffins along with a C7+ partially unsaturated fraction, and the first and second paraffin fractions combined into a total C3-C6 paraffin fraction, which can in turn be subjected to a dehydrogenation or aromatization process with hydrogen gas as byproduct, and the hydrogen gas recycled for use in producing the jet-diesel fraction.
