Patent number: 8461215Abstract: The invention provides a method for rendering coal as an environmentally essentially carbon dioxide-neutral fuel. Carbon dioxide produced from coal combustion is captured, purified, combined with coalbed methane or any other natural methane or natural gas source, or with hydrogen, and reacted under reaction conditions sufficient to form methanol and/or dimethyl ether, which can be used as fuel or feedstock for derived synthetic hydrocarbons and products.Type: GrantFiled: April 7, 2010Date of Patent: June 11, 2013Assignee: University of Southern CaliforniaInventors: George A. Olah, G. K. Surya Prakash
