Assistant absorption agent for removing foreign matter from petroleum product and method of producing the same

Abstract

The present invention relates to an absorbing aid for removing impurities of oil products and the preparation method thereof belonging to the chemical products technical field, which aims to provide an absorbing aid with higher decolorizing capacity, higher adsorption capacity as well as lower residual oil ratio and the preparation method thereof. The technical points lie in the raw material components of absorbing aid and the weight percentage, i.e. the content of attapulgite is 20-50 percent of attapulgite raw ore 28-40, bentonite raw ore 60-70 and activated carbon 1-2. The powder obtained by activating, heating, stirring, squeezing, roasting and grinding the attapulgite raw or is mixed and stirred together with the powder obtained by catalyzing, squeezing, rinsing, pressing, calcining and grinding the bentonite raw ore and the activated carbon; absorbing aid product is obtained via extrusion, dehydration and granulation. The absorbing aid is relatively large in specific surface area, strong in absorbing capacity, stable in performance, low in residual oil ratio, low in free acid, fast in filtering rate, strong in decolorizing capacity and high in activity degree, which can improve oil productivity as well as yield and reduces the production cost of users.

Description

Technical field: [0001] The invention belongs to the technical field of chemical products. In particular, it is widely used in the purification of aromatics in the petrochemical industry, the refining of aviation kerosene, the refining of diesel oil, lubricating oil, base oil and other products, and the removal of residual olefins, colloids, asphalt, basic nitrides, and metal complexes in oil products. Adsorption aid for impurities such as compound and preparation method thereof. Background technique: [0002] At present, it is used at home and abroad for the purification of aromatics in the petrochemical industry, the refining of aviation kerosene, the refining of diesel oil, lubricating oil, base oil and other products, and the removal of residual olefins, colloids, asphalt, basic nitrides, and metal complexes in oil products. Granular white clay with other impurities is basically obtained by catalytic treatment of bentonite. [0003] Bentonite is a rock with montmorillo...

AI Technical Summary

Problems solved by technology

However, due to the low grade of bentonite raw ore in our country, coupled with the low level of development and processing technology and relatively backward equipment, the product quality is not high, the decolorization power is low, the adsorption capacity is weak, the filtration speed is slow, the oil carrying rate is high, and the market competitiveness is poor.
