A method and apparatus for the generation of synthetic motor fuels and additives to oil fuels, C 1 -C 4 alcohols, hydrogen, methane, synthesized gas (H 2 +C0 2 ) by hydrothermal treatment of carbonaceous compounds by providing a two-stage carbon gasification process operated under the supercritical conditions of H 2 0and C0 2 , including a first stage gasification reactor having a reaction zone for the conversion of carbonaceous compounds and a second stage reactor for the conversion of the products of the first stage reactor. Feed to first stage is an aqueous suspension of carbonaceous compound in an amount of at least 30% by weight and an alkali metal or alkaline earth metal catalyst or reactive OH-species from an electrolyzer. Reaction products from pass to the second stage reactor over a copper-zinc catalyst at pressure and temperature, so that any gases generated in the first stage are converted into C 1 -C 4 alcohols. |
