TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The catalyst is free of rhenium and alloys.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The separating step involves separating the higher alcohols from the ethanol. The mixed acid feed comprises acetic acid, the higher acid and acetone, and the crude alcohol product further comprises isopropanol. The process further involves contacting acetic acid and hydrogen, in an auxiliary reactor, under conditions effective to form the acetone. The alcohol composition comprises 0.1-10 wt.% of isopropanol, based on the total weight of the alcohol composition. The separating step involves: separating a first portion of the crude alcohol product into an ethanol stream and a higher alcohol stream; purifying the ethanol stream to form a purified ethanol stream; and combining at least a portion of the higher alcohol stream with the purified ethanol stream to form the alcohol composition. The denatured mixed alcohol composition comprises the fuel denaturant (1.5-3 wt.%). The fuel denaturant is selected from natural gasoline, gasoline blend stocks or unleaded gasoline, or comprises diesel fuel. The denatured mixed alcohol composition comprises (wt.%): ethanol (92-98), propanol (0.01-8) and fuel denaturant (1.5-3). The denatured mixed alcohol composition comprises not greater than 1.0 wt.% of water. Preferred Components: The mixed acid feed comprises (wt.%): acetic acid (80-99) and a higher acid (0.01-20). The alcohol composition comprises less than 1 (preferably less than 0.5) wt.% of higher alcohols; or 0.01-20 (preferably 0.04-20, especially 0.5-10) wt.% of higher alcohols. The higher acid is propionic acid. The mixed acid feed comprises at least 0.04 (preferably at least 0.08, especially at least 0.5) wt.% of propionic acid. The alcohol composition comprises (wt.%): ethanol (greater than 80, preferably 92-99) and propanol (0.01-8). The crude alcohol product further comprises (wt.%): ethanol (5-71), ethyl acetate (0.01-20), acetaldehyde (0.01-10), isopropanol (0.01-10), diethyl ether (0.01-20), acetic acid (0-90), higher ester (0.001-5), and water (5-35), based on the total weight of the crude ethanol product. The mixed acid feed comprises greater than 0.01 (preferably at least 0.04, especially at least 0.08, particularly at least 0.5) wt.% of propionic acid. The mixed alcohol composition comprises (wt.%): ethanol (80-99, preferably 92-99) and propanol (0.01-8). The mixed alcohol composition comprises the heavier alcohol (1-10 wt.%). The mixed alcohol composition comprises (wt.%): ethanol (50-99), and higher alcohol (0.01-40). The fuel blend is selected from E10, E15, E85 or E-Diesel. The higher alcohol is propanol.
