Comprehensive recycling method of waste FCC (fluid catalytic cracking) catalyst
The invention discloses a comprehensive recycling method of a waste FCC (fluid catalytic cracking) catalyst. The method comprises the following steps: S1, performing magnetic separation on the waste FCC catalyst to obtain a low-magnetic agent and a high-magnetic agent; s2, the high-magnetism agent is ground into fine powder through a ball mill, and high-magnetism agent fine powder is obtained; returning the low-magnetism agent to an oil refinery after the low-magnetism agent meets the standard through a micro-reaction activity test; s3, the high-magnetic agent fine powder is subjected to secondary magnetic separation, and a metal-free material and a metal-containing material are obtained; s4, uniformly mixing the metal-containing material with a residual oil waste catalyst and sodium carbonate in proportion, and performing high-temperature roasting in a rotary kiln to obtain clinker; s5, the clinker is put into a leaching tank, clear water is added for soaking, and leaching liquid and tailings are obtained after solid-liquid separation; s6, the tailings are evenly mixed with coke, silica, limestone and fluorite, the mixture is put into an electrothermal furnace to be subjected to reduction smelting, and ferronickel melt and slag melt are obtained; and S7, the ferronickel melt is cast to form a ferronickel product, and the slag melt is subjected to water quenching cooling to form water-quenched slag.
本发明公开了一种废FCC催化剂的综合回收利用方法，S1、废FCC催化剂经磁选分离获得低磁剂和高磁剂；S2、利用球磨机将所述高磁剂研磨成细粉，获得高磁剂细粉；所述低磁剂经微反活性测试符合标准后，返回炼油厂；S3、将所述高磁剂细粉进行二次磁选，获得不含金属材料和含金属材料；S4、所述含金属材料与渣油废催化剂、纯碱按比例混合均匀，进入回转窑高温焙烧，获得熟料；S5、所述熟料投入浸出槽，加入清水浸泡，固液分离后，获得浸出液和尾渣；S6、所述尾渣与焦炭、硅石、石灰石、萤石混合均匀，投入电热炉进行还原熔炼，获得镍铁熔体和炉渣熔体；S7、所述镍铁熔体经浇铸形成镍铁产品，炉渣熔体经水淬冷却形成水淬渣。
