HT series activated clay is made of bentonite as raw material and refined by acidification process. It has a larger specific surface area and more activated acid centers, so it has strong adsorption and catalytic ability.Industrially, it is often used in the decolorization and refining of various vegetable oils, animal oils and cosmetic raw material greases, the refining of mineral oils and the recycling of waste oils. It can be used for sewage treatment and toxic gas filtration catalytic cracking in the petroleum industry when it is made into granules.

KH series granular clay is made of activated clay as the main raw material and is scientifically formulated and chemically treated. It has a higher effective specific surface area and adsorption capacity. It is widely used in the purification of aromatics in the petrochemical industry, aviation kerosene refining, and also used in lubricants. Base oil, diesel oil and other oil products, to remove residual olefins, gums, asphalt, basic nitrogen compounds and other impurities in the oil products.

At present, the domestic petrochemical industry generally has two methods to remove olefins in aromatics. One is hydrorefining. This method is more effective for a single narrow fraction. However, for the broad fraction of aromatic products from benzene to xylene, the depth of the hydrogenation reaction is difficult to take into account, and it will cause the loss of aromatics. Another method to remove olefins with clay. However, in the process of white soil treatment, there is a short use period of white soil, and frequent replacement increases the loss of aromatics; a large amount of waste white soil needs to be incinerated or landfilled, which has a large impact on the environment and high costs.
