Abstract

The invention provides a purification agent applied to treatment of automobile exhaust and a preparation method thereof. The purification agent comprises a carrier and a coating coated on the carrier, wherein the coating is prepared from the following raw materials: calcium aluminate, hafnium hydroxide, praseodymium oxide, tin-doped zinc oxide, 2,2,4-trimethyl-1,3-pentanediol isobutyrate, potassium gadolinium tungstate, selenourea, graphene oxide, silver loaded zeolite powder, pseudo-boehmite, carboxyl modified silicon dioxide, methylcellulose, shell powder, tourmaline powder, ferric phosphate, cerium molybdate, titanium cyanide, carbon molecular sieve-220 and additives. The purification agent is excellent in purification effect on the automobile exhaust; the treated automobile exhaust is obviously lower than the state-specified emission limit standard; in addition, the purification agent applied to treatment of the automobile exhaust is simple in preparation process and low in cost, and is extremely suitable for large-scale production and application.

Description

technical field [0001] The invention belongs to the technical field of automobile tail gas treatment, and in particular relates to a purifying agent for automobile tail gas treatment and a preparation method thereof. Background technique [0002] The tail gas emitted by automobiles is a major source of air pollution and one of the important causes of the greenhouse effect, the hole in the ozone layer, acid rain and black rain. Exhaust gas from automobiles contains thousands of chemical substances, all of which are harmful except nitrogen, oxygen and water vapor. These harmful substances generally include carbon monoxide, soot, hydrocarbons, nitrogen oxides, etc. At the same time, methyl lead or tetraethyl lead anti-knock agents are added to the popular fuel oil, so the substances produced after combustion also contain lead and other substances. Compounds pose a serious threat to human health. [0003] In order to solve the pollution problem of automobile exhaust exhaust, t...
