Abstract
A method to produce syngas from a feed oil comprising the steps of increasing a pressure of a slurry catalyst; increasing a temperature of the pressurized slurry stream; increasing a pressure of the feed oil; increasing a temperature of the pressurized feed stream; mixing the hot slurry stream and the hot oil stream; increasing a temperature of the mixed stream in a combined heater to produce a hot mixed stream; maintaining upgrading reactions of hydrocarbons in the supercritical reactor to produce a supercritical effluent; reducing a pressure of the supercritical effluent; separating the depressurized effluent in a separator to produce a gas stream; separating the gas stream to produce a light hydrocarbon stream; mixing the light hydrocarbon stream and a catalyst feed; introducing the hot feed to a steam reformer; maintaining water gas shift reactions of the light hydrocarbon gases in the steam reformer to produce a reformer effluent.
