The invention relates to an installation and a process for the production of liquid fuels starting from a solid feedstock that contains the organic material in which:a) the solid feedstock is subjected to a gasification stage so as to convert said feedstock into synthesis gas,b) the synthesis gas is subjected to a purification treatment,c) the purified synthesis gas is subjected to a conversion stage that comprises the implementation of a Fischer-Tropsch-type synthesis so as to convert said synthesis gas into a liquid effluent and a gaseous effluent,d) the liquid effluent is fractionated so as to obtain a gaseous fraction, a naphtha fraction, a kerosene fraction and a gas oil fraction, ande) at least a portion of the naphtha fraction is recycled in gasification stage a).

The purpose of the invention is to provide a heavy oil reforming method which reforms a heavy oil to give a fuel suitable for a gas turbine, eliminates sulfur and vanadium, i.e., harmful components, from a heavy oil, and enables almost all the hydrocarbons in the heavy oil to be used in gas turbine combustion; an apparatus therefor; and a gas turbine power generation system using the reformed heavy oil as fuel. This method comprises reacting a heavy oil with supercritical water and then with a scavenger for sulfur and vanadium to eliminate sulfur and vanadium from the heavy oil. The apparatus for reforming a heavy oil is equipped with a reactor for reacting a heavy oil with supercritical water, a scavenging apparatus filled with a scavenger for scavenging sulfur and vanadium in the heavy oil, and a connecting pipe for connecting the reactor and the scavenging apparatus. The gas turbine power generation system has a burner for burning a heavy oil reformed with the reforming apparatus and a gas turbine driven by a combustion gas generated by the burner.

Supercritical conversion of hydrocarbons boiling above 538° C. (1000° F.) with a solvating hydrocarbon at a weight ratio of solvating hydrocarbon to high-boiling hydrocarbons of at least 2:1 and at conditions above the critical temperature and pressure of the high-boiling hydrocarbons-solvent mixture, in the presence of hot fluidized solids. The hydrocarbons are supplied to a reaction zone at a temperature below that of the hot solids supplied thereto, whereby the resulting hydrocarbons-solids suspension has a thermal equilibrium temperature corresponding to the reaction temperature. The conversion has high rates of sulfur, nitrogen and metals removal, nearly complete conversion to lower molecular weight products, high naphtha and distillate selectivity, and low coke formation. The supercritical conversion can replace crude distillation, vacuum distillation, solvent deasphalting, coking, hydrocracking, hydrotreating, and / or fluid catalytic cracking, and / or used in parallel with such unit operations for debottle-necking or increasing capacity.
