(ZA9900736-A)   NOVELTY - The synthesis gas comprising hydrogen and carbon monoxide mixture is made to contact a hydrocarbon synthesis catalyst under effective conditions to form hydrocarbons. A part of synthesized hydrocarbons reacts with hydrogen (produced from synthesis gas) in presence of hydroconversion catalyst to alter the molecular structure of hydrocarbon and to produce a hydrogen rich tail gas.    USE - For forming synthetic crude oil, liquid fuel (e.g. motor gasoline, diesel fuel), olefins, solvents, lubricating oil (e.g. turbine and metal working oils), industrial oil (e.g. well drilling fluid, heat transfer fluid), medicinal oil, waxy hydrocarbons, nitrogen and oxygen content compounds.    ADVANTAGE - The hydrogen required for rejuvenating hydrocarbon synthesis catalyst, hydroconversion of synthesized hydrocarbon and hydrodesulfurization of well liquid is obtained within the integrated hydrocarbon synthesis plant, without depending on external source of hydrogen.
