METHOD FOR MANUFACTURE A CATALYST MATERIAL FROM DESULFURIZATION WASTE CATALYST OF AN OIL REFINERY BY SEPARATING VANADIUM FROM WASTE CATALYST AND PRODUCING THE RESIDUAL MATERIAL EXCEPT THE VANADIUM AS CARBONATE

摘要

PURPOSE: A method for manufacture a catalyst material from desulfurization waste catalyst of an oil refinery is provided to efficiently separate vanadium from waste catalyst by adding Mono-Octylamine(CH3(CH2)7NH2) to the waste catalyst.;CONSTITUTION: A method for manufacture a catalyst material from desulfurization waste catalyst of an oil refinery comprises the steps of: mixing a desulfurization waste catalyst with concentrated sulfuric acid(97%) and obtaining dry reactant by heating and stirring the mixture; separating vanadium from the mixture by adding Mono-Octylamine(CH3(CH2)7NH2) to the mixture; changing the sulfuric acid into a carbonate mixture through the heating and stirring operation at PH 7-8; and manufacturing the carbonate mixture from which moisture and salt are removed.;COPYRIGHT KIPO 2011
