Patent ID: 8536234

Claim:
A method for generation of synthetic motor fuels, C 1 -C 4 alcohols, hydrogen, methane, synthesized gas (H 2 +CO 2 ), and additives to oil fuels by hydrothermal treatment of carbonaceous compounds comprising the steps of: providing a two-stage process operated under the supercritical conditions of H 2 O and CO 2 , including a first stage gasification reactor having a reactor zone for the conversion of carbonaceous compounds and a second stage reactor for the conversion of the products of the first stage; feeding a aqueous suspension of carbonaceous compound and an alkali metal or alkaline-earth metal catalyst through said first stage gasification reactor as a supercritical fluid at a volume velocity of 0.01-0.05 g of carbon per 1 cm 3 per hour, at a carbon/catalyst mole ratio of between about 70/1 and 90/1, at a temperature of 390-450° C., and under a pressure of about 225 to 500 bars; feeding the reaction products from the first stage to the second stage over a copper-zinc catalyst at a temperature of 200-280° C. and under the pressure of at least about 100 bars so that any gases generated in the first stage are converted into C 1 -C 4 alcohols fraction with a weight ratio of C 1 -C 2 to C 3 -C 4 equal to between about 0-35% to 100-65%.
