Method for alcohol upgrading to jet, diesel, gasoline, and valuable co-products

A method for converting an alcohol to a jet-diesel hydrocarbon fraction, the method comprising:

• (i) contacting the alcohol with a pillared two-dimensional zeolite catalyst having an MFI structure at a temperature of at least 200° C. and up to 500° C. to result in conversion of said alcohol to said hydrocarbons, wherein said hydrocarbons comprise:
• (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;
• wherein the first mixed olefin fraction accounts for at least 25 carbon mol % of total fractions (a)-(c), and the conversion of the alcohol is energy neutral or exothermic;
• (ii) subjecting said first mixed olefin fraction to an oligomerization process in which the first mixed olefin fraction is contacted with an oligomerization catalyst at a temperature of at least 40° C. and up to 300° C. to result in a second paraffin fraction containing C3-C6 paraffins along with a C7+ partially unsaturated fraction, and combining said first and second paraffin fractions to result in a total C3-C6 paraffin fraction;
• (iii) subjecting at least a portion of said total C3-C6 paraffin fraction to one or both of the following processes:
• (iii-a) a dehydrogenation process in which at least a portion of said total C3-C6 paraffin fraction is contacted with a dehydrogenation catalyst at a temperature of at least 500° C. and up to 600° C. to form a second mixed olefin fraction containing a mixture of C3-C6 olefins along with hydrogen gas, and (iii-b) an aromatization process in which at least a portion of said total C3-C6 paraffin fraction is contacted with a ZSM-5 zeolite catalyst at a temperature of at least 400° C. and up to 600° C. to form an aromatic fraction and hydrogen gas;
• and
• (iv) subjecting the C7+ partially unsaturated fraction, produced in the step (ii) oligomerization process, to a hydrogenation process by contacting the C7+ partially unsaturated fraction with a precious metal-containing hydrogenation catalyst in the presence of hydrogen gas produced by either or both of processes (iii-a) and (iii-b) at a temperature of at least 100° C. and up to 300° C. to produce the jet-diesel hydrocarbon fraction, wherein the jet-diesel hydrocarbon fraction contains a C8+ paraffin fraction with substantially no olefin or aromatic fraction.
