Conversion of carbon dioxide to methanol using bi-reforming of methane or natural gas

摘要

The invention provides for a method of forming methanol by combining a mixture of methane, water and carbon dioxide under specific reaction conditions sufficient to form a mixture of hydrogen and carbon monoxide which are then reacted under conditions sufficient to form methanol. The molar ratio of hydrogen to carbon monoxide is at least two moles of hydrogen to one mole of carbon monoxide and the overall molar ratio between methane, water and carbon dioxide is about 3:2:1. Methane, carbon dioxide and water are bi-reformed over a catalyst. The catalyst includes a single metal, a metal oxide, a mixed catalyst of a metal and a metal oxide or a mixed catalyst of at least two metal oxides.
