Abstract
A method for converting an alcohol to a hydrocarbon, the method comprising contacting said alcohol with a metal-loaded zeolite catalyst at a temperature of at least 100° C. and up to 550° C., wherein said alcohol can be produced by a fermentation process, said metal is a positively-charged metal ion, and said metal-loaded zeolite catalyst is catalytically active for converting said alcohol to said hydrocarbon.
Claims13
A system for converting ethanol to a mixture of hydrocarbon compounds useful as a fuel or as a blendstock component of a fuel, comprising:
- a source of a feedstock comprising ethanol, wherein the ethanol is in an aqueous solution at a concentration of no more than about 20% (vol/vol);
- a boiler unit in fluidic communication with the source of the feedstock and configured to volatilize the feedstock;
- and
- a reactor unit in fluidic communication with the boiler unit and configured to house a catalyst catalytically active for directly converting the ethanol to a mixture of hydrocarbons, wherein the catalyst consists of a zeolite loaded with at least one positively-charged metal ion selected from the group consisting of alkali metal ion, alkaline earth metal ion, lanthanide metal ion, copper ion, zinc ion, titanium ion, vanadium ion, cadmium ion, gallium ion, and indium ion, and wherein said mixture of hydrocarbon compounds substantially corresponds to a fuel selected from gasoline, kerosene, diesel, and jet propellant.
