1. A method for rendering petroleum oil as an essentially environmentally carbon dioxide-neutral fuel and regenerative carbon source for producing methanol or dimethyl ether, which comprises:
- subjecting petroleum oil to refining or combustion conditions sufficient to produce carbon dioxide;
capturing and purifying the produced carbon dioxide; and
combining the purified carbon dioxide with water and a suitable light hydrocarbon fraction or with hydrogen produced from water under reaction conditions sufficient to produce methanol or dimethyl ether, so that the carbon dioxide generated from the petroleum oil is not introduced into the atmosphere, thus rendering the petroleum oil as an essentially environmentally carbon dioxide-neutral fuel and regenerative carbon source.

Abstract
The invention provides a method for rendering petroleum oil as an essentially environmentally carbon dioxide-neutral fuel and source material. Carbon dioxide produced from petroleum oil combustion is captured, purified, combined with steam and light hydrocarbon fractions, 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.
