ABSTRACT:
A method for producing methanol and dimethyl ether using the air as the sole source of materials is disclosed. The invention relates to a method for producing methanol by removing water from atmospheric air, obtaining hydrogen from the removed water, obtaining carbon dioxide from atmospheric air; and converting the carbon dioxide under conditions sufficient to produce methanol. Thereafter, the methanol can be dehydrated to produce dimethyl ether or further processed to produce synthetic hydrocarbons, polymers, and products derived from them.
