Description

Technical Field

[0002] The oil refining industry is one of the important industries of the national economy. With the continuous expansion of global oil refining scale, the improvement of oil product standards, and the continuous growth of chemical raw materials, the demand for oil refining catalysts has been growing steadily. As the core technology of oil refining and petroleum cracking to produce chemical raw materials, catalytic hydrogenation plays a vital role in oil processing. At present, hydrogenation catalysts mainly use alumina or aluminum-silicon composite carriers to load metal active components (Mo, Co, W, Ni). Such supported metal catalysts are widely used in the field of selective hydrogenation catalysis due to their high activity and hydrogenation selectivity. The activity of hydrogenation catalysts will decrease after a long period of operation and eventually become inactivated. If these catalysts that have been abandoned due to failure are not effectively disposed of and randomly piled up, on the one hand, a large amount of land resources will be occupied and the cost of the enterprise will be increased; on the other hand, some toxic and harmful substances adsorbed by the catalyst during use will enter the natural environment, especially the water body, which will cause serious harm to the environment. If not handled in time, it will become a new source of pollution. Therefore, the treatment of waste catalysts needs to comply with strict environmental regulations. The national hazardous waste catalog clearly lists waste hydrogenation catalysts as hazardous wastes. The content of molybdenum, nickel, vanadium, cobalt, tungsten and other elements in hydrogenation catalysts is higher than that in their ores. For countries with scarce metal resources, recycling waste hydrogenation catalysts as metal resources is imperative and also of great significance to sustainable development. A large amount of process wastewater will be generated during the entire recycling process, and the emission requirements are relatively strict, Mo<0.5mg / L, Ni<0.5mg / L, Co<1mg / L. In order to stabilize the emission standards, in addition to adjusting pH precipitation, auxiliary reagents such as flocculants and heavy capture agents need to be added;
