HYDROCARBON CONVERSION CATALYST AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2004 - IPC

FIELD: catalysts in petrochemical processes.

SUBSTANCE: invention provides hydrocarbon conversion catalyst including x-ray-amorphous carbon obtained by vaporization of carbon-containing material and having following characteristics: temperature of in-air oxidation start T_so≤320^оС; maximum oxidation rate temperature T_omr≤590^оС; temperature of in-air oxidation end T_0e≤630^оС; initial hydrogenolysis rate at 700^оС in absence of hydrogen-activating catalyst V_s≥2.08 wt % carbon/h; and limiting amount of MnO-4

ion consumed in contact with 1g of above-mentioned carbon in solution ≤16 mmole. Preparation of catalyst comprises vaporization of carbon-containing material exposed to energy stream supplied at a level of 50 to 300 W/mm², precipitation of fulleren-containing carbon black obtained after vaporization, extraction of fullerens from this carbon black with organic solvent, separation of the precipitate, washing and subsequent drying thereof.

EFFECT: extended catalytic spectrum, prevented coking and sensitivity to attack of usual catalytic poisons.
