Due to its good adsorption, ion exchange, catalytic, acid resistance and stability, zeolite is thus widely used as a new environmental material in environmental remediation, green building materials, agricultural farming, petrochemicals and other fields, thus driving the large-scale growth of the global zeolite market.

The heavy metal content on the catalytic cracking balancing agent in China are more than 10 mg/g, so foreign sulfur reduction additives are not necessarily applicable to domestic catalytic cracking units. The Institute of Petrochemical Sciences has studied the transformation mechanism of sulfide in the catalytic cracking process, as well as the transformation process of sulfide adsorption by new materials, and developed desulfurization additives that can process raw materials containing high nickel and high vanadium.

At this stage, researchers mainly improve the performance of catalytic cracking tower bottom oil cracking additives by improving their acid properties and pore structure. In response to the characteristics of seasonal demand for diesel and high gasoline inventory.

At present, in order to solve the problem of easy scaling of key equipment in the process of oil processing, domestic researchers have conducted a lot of research on scale inhibitors and developed scale inhibitors with strong target and obvious scale inhibition effect; according to their use, they can be classified into FCC slurry scale inhibitor and hydrocracking scale inhibitor.

In response to some problems in the refining process and the addition of one or more fine chemical products as supplementary additives, this type of refining additives have the characteristics of targeted, convenient and flexible, can play a role in improving the catalyst as well as the refining process and equipment.

Zinc oxide desulfurizer is widely used in the fine desulfurization of various petrochemical raw materials gas and industrial gas, with the advantages of high desulfurization precision and large sulfur capacity. Zinc oxide desulfurization agent is divided into normal temperature zinc oxide desulfurization agent and medium temperature (high temperature) zinc oxide desulfurization agent, the former's use temperature 10 ~ 120 ℃, the latter is 220 ~ 450 ℃, clover appearance, 30% increase in external surface area.
