In recent years, China's refining industry is developing rapidly, the processing capacity of crude oil has been greatly improved, and the annual crude oil production is also increasing year by year. Because the quality of gasoline in automobile exhaust will have a great impact on the environment, so the quality of processed petroleum products needs to be improved. In order to improve China's refining technology, China has joined the world trade organization (wto) and hopes to acquire more refining methods through international integration.

As we all know, the core technology of oil refining and petrochemical industry is catalytic technology, and the soul of catalytic technology is catalyst. In modern oil refining and chemical industry, more than 90% of chemical reactions are realized through catalytic reaction. In the catalytic reaction, catalytic cracking catalyst is the catalyst with the largest consumption in petroleum industry, 80% of domestic gasoline and 40% of diesel fuel are from catalytic cracking.

In oil refining process, needs to have a fairly active refining catalyst can realize the crude oil refining, and in the actual production of crude oil, because there are a high temperature and high pressure in the production environment, heavy metals, water vapor, carbon deposition caused by factors such as catalyst loss of activity, the activity of the catalyst can not continue to use in the oil refining process, should be dealt with as waste.

As the waste catalyst itself contains a large number of heavy metals, it has certain pollution to the environment, so how to effectively deal with the waste catalyst and improve the economic and social benefits of the waste catalyst is an urgent problem to be solved.

It is precisely because of the implementation of low-sulfur fuel standards by refiners that refining catalysts are widely used and the business of refining catalysts is growing strongly. Therefore, the progress of catalyst manufacturers plays an important role in promoting the development of pillar industries such as petrochemical industry and protecting the environment for human beings. The demand changes of global catalyst market also reflect this development trend.
