Abstract:
1. A process for hydrogenating carbon dioxide in the presence of a catalyst to generate methanol as a main product comprising: a) preparing a basic material comprising a copper base plate with porous layers on both sides of the copper base plate, the porous layers including metallic zinc that has been moistened with an electrolyte and immobilized by electrolysis, said preparing including providing the porous layers with a catalyst for hydrogenating carbon dioxide, the catalyst being selected from the group consisting of zinc oxide, copper oxide, or other catalysts; b) generating hydrogen gas from the basic material in sealed spaces by electrochemical reactions, oxidizing the porous layers to produce oxide layers, and allowing the generated hydrogen gas to reach a condition of high pressure; c) heating the porous layers to allow the porous layers and the sealed spaces to reach a state of high-temperature, high-pressure, and dehydration; and d) forcing carbon dioxide into the sealed spaces and allowing the carbon dioxide to react with the generated hydrogen gas and thereby generating methanol as a main product.
