MOTOR FUEL PRODUCTION PROCESS Russian patent published in 1999 - IPC

FIELD: motor fuel production. SUBSTANCE: in a method where fuel stock is mixed with hydrogen and subjected to high-temperature pyrolysis, novelty consists in that fuel stock (natural gas, [petroleum, most long fractions from petroleum processing including heavy residues) is subjected to plasma-chemical pyrolysis in hydrogen-containing gas stream to yield pyrolysis gas, carbon black, and hydrogen sulfide from reduction of sulfur compounds. Pyrolysis products are further treated to remove carbon black, after which rare metals are precipitated by known methods and hydrogen sulfide is subjected to dissociation in microwave plasma to form polymer sulfur and hydrogen, the latter being returned into pyrolysis process. Finally, purified gas is used for synthesis of motor fuel. EFFECT: enlarged motor fuel resource. 1 dwg
