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.
