Chinese invention patent CN103708995A, 2014.4.9 discloses a coal-to-methanol fusel oil desulfurization and deodorization method, by passing a certain amount of ozone into the fusel oil and stirring, then adding diatomaceous earth to stir, and filtering to obtain Fusel oil for removing peculiar smell; Chinese invention patent CN 106187690A, 2016.12.7 discloses a kind of fusel oil odor remover, this fusel oil odor remover is made of alum, zinc sulfate, calcium hypochlorite, aluminous acid Sodium, sodium sulfate, zinc oxide, sodium trifluoromethanesulfonate and bentonite are formulated according to a certain ratio. The above two technical solutions both use chemical oxidation and physical adsorption to remove the odor in fusel oil. A strong oxidizing oxidizing agent is used. Due to the complex composition of fusel oil, some components in fusel oil may be oxidized and other side reactions may occur, which will affect the deodorization effect of fusel oil

Abstract

The invention discloses an odor adsorbent, and a preparation method and a use thereof. The odor adsorbent can be used as a coal-to-methanol fusel oil odor adsorbent. Bentonite, diatomaceous earth, sodium humate, anthracite and walnut shells are combined to form the odor adsorbent, play respective characteristics and complement each other. The odor adsorbent has the advantages of uniform particles, large specific surface area, prosperous micro-pore structure, reasonable aperture, richness in capillary tubes, and high adsorption capacity, and has a good fusel oil odor removal effect when applied to coal-to-methanol; and the preparation method has the advantages of simplicity in operation, low production cost, good treatment effect, no environmental pollution and repeated use.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of chemical production, and in particular relates to an odor adsorbent and a preparation method and application thereof. [0003] 【Background technique】 [0004] Methanol is a basic chemical raw material and has a wide range of uses in chemical, pharmaceutical, light textile and other fields. Methanol can be used to directly synthesize oxygen-containing chemical products, mainly used to manufacture a series of organic chemical products such as formaldehyde, methylamine, dimethyl ether, etc., and can also be added to gasoline for blending or replacing gasoline as power fuel and used to synthesize methanol protein. Among the world's basic organic chemical raw materials, methanol consumption is second only to C 2 H 4 , C 3 H 6 and C 6 H 6 , ranked 4th. Coal-to-methanol is an important part of coal chemical projects. The contradiction between the development of China's chemical industry and the shortage of...
