METHOD FOR MANUFACTURING STERILIZING ZEOLITE USING A WASTE RESID FLUIDIZED CATALYTIC CRACKING CATALYST CAPABLE OF SAVING COSTS REQUIRED FOR RAW MATERIALS BY RECYCLING THE WASTE RESID FLUIDIZED CATALYTIC CRACKING CATALYST

摘要

PURPOSE: A method for manufacturing sterilizing zeolite using a waste resid fluidized catalytic cracking(RFCC) catalyst is provided to stably supply raw materials to a zeolite manufacturing process.;CONSTITUTION: Waste RFCC is directly ion-exchanged or is ion-exchanged after oxidization. The waste RFCC is composed of 60-70% of silicon dioxide, 25-32% of aluminum oxide, 0.1-0.5% of iron, 0.1-0.4% of nickel, and 0.1-0.4% of vanadium. The waste RFCC is generated from the oil petroleum refining process of a petrochemical industry. A filtering process, a washing process, a drying process, and a grinding process are implemented after the ion-exchanging process. A vibration mill and a centrifugal-vibration mill are used for the grinding process. Copper sulfate and ammonium nitrate are used for the ion-exchanging process.;COPYRIGHT KIPO 2012
