METHOD FOR EXTRACTING USEFUL COMPONENT INVOLVED IN THE SURFACE OF WASTED CATALYST WITH HYTROGENATED DESULFURIZATION HEAVY OIL USING THERMAL CHEMICAL TYPE

摘要

PURPOSE: A method for extracting a useful component of the surface of a used catalyst with hydrogenated desulfurization heavy oil using a thermal chemical method is provided to separate used oil from the surface of an HDS used catalyst by the thermal chemical method, thereby reducing contamination of air due to a fuel. CONSTITUTION: Extracted liquid is made by mixing soft water with a surfactant. The extracted liquid is sequentially inputted to a combustion cup(2) and a constant temperature bath(3). The extracted liquid is heated. Mixed solution mixing an oil component of a used catalyst surface with the extracted liquid is extracted. After washing, the oil component and the other components are separated by centrifugation of the mixed solution.
