METHOD OF CARBON MATERIAL AND HYDROGEN PRODUCING Russian patent published in 1997 - IPC

Abstract RU 2086502 C1

FIELD: chemical technology. SUBSTANCE: nickel-containing catalyst is loaded in flow-type reactor, heated in hydrogen flow to 475 C and methane is added. Decomposition is carried out at 550-600 C. After catalyst activity decrease by 3-5-fold temperature is increased to 700 C. Propane can be used instead methane and decomposition is carried out at 475-550 C. Ratio CnHm:H2 = (3-10): (1-10) l/h. Yield of carbon is 114.8-386.4 g/g reduced catalyst. Method is used for ferromagnetic ink, graphite pigments, rubbers and plastics making. EFFECT: improved method of producing. 4 cl, 1 tbl
