Method for co-processing waste nickel catalyst and secondary aluminum ash

The invention belongs to the technical field of comprehensive utilization of resources, and particularly discloses a method for co-processing a waste nickel catalyst and secondary aluminum ash. The method comprises the following steps: distilling the waste nickel catalyst to remove organic matters, recovering nickel by adopting acid leaching, mixing acid leaching residues with secondary aluminum ash and hydrothermal residues, pressing into a raw material blank, and carrying out primary sintering to obtain a foamed ceramic product. According to the method, the component characteristics of solid waste are fully utilized, through the synergistic effect of solid waste components, efficient recycling of valuable metal is achieved, meanwhile, hazardous waste is converted into high-added-value products, the pollution problem is effectively solved, the treatment cost is low, economic benefits are remarkable, and good application prospects are achieved. 本发明属于资源综合利用技术领域，具体公开了一种废镍催化剂与二次铝灰协同处置的方法。本发明方法先将废镍催化剂蒸馏去除有机物，之后采用
