METHOD OF OBTAINING CARBON CARRIER FOR CATALYSTS Russian patent published in 2009 - IPC B01J32/00 B01J21/18 

FIELD: chemistry.

SUBSTANCE: carbon-black paste and gas obtained during electrocracking of liquid organic products are used as raw material for obtaining carrier. Carbon-black paste is a mix of carbon-black and high-molecular organic compounds absorbed on its surface. Electrocracking gas includes hydrogen, acetylene, C₁-C₄ alkanes, C₂-C₄ alkenes. Carbon-black paste is fed to drying aggregate and dried at 130-150°C in air atmosphere for 160-180 minutes, granulated, fed to reactor and exposed to 750-850°C in inert gas atmosphere for 100-120 minutes. Then temperature is lowered to 450-550°C, and processing by electrocracking gas is performed. Compressed material obtained is processed by oxidation agent (steam and air mix, carbon dioxide). For that purpose electrocracking gas supply to reactor is stopped, reactor temperature is increased to 750-900°C, then oxidising agent is fed until sample weight reduction by 7-60%.

EFFECT: material with enhanced adsorption surface.
