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 CN106187690A, 2016.12.7 discloses a fusel oil odor remover, the fusel oil odor remover is composed of alum, zinc sulfate, calcium hypochlorite, sodium aluminate , sodium sulfate, zinc oxide, sodium trifluoromethanesulfonate and bentonite are prepared according to a certain ratio. The above two technical solutions both use chemical oxidation and physical adsorption to remove the odor in fusel oil. When it comes to oxidizing agents with strong oxidizing properties, 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

【Technical Field】 [0001] The invention belongs to the field of chemical production, and specifically relates to a fusel oil odor adsorbent and a preparation method and application thereof. 【Background technique】 [0002] Methanol is a basic chemical raw material, and it has a wide range of uses in the chemical, pharmaceutical, textile and other fields. Methanol can be used to directly synthesize products containing oxidants, mainly for the manufacture of a series of organic chemical products such as formaldehyde, methylamine, dimethyl ether, etc. It can also be blended with gasoline or replaced by gasoline as power fuel and used to synthesize methanol protein. Among the basic organic chemical raw materials in the world, methanol consumption is second only to C 2 H 4 , C 3 H 6 And C 6 H 6 , In the 4th place. Coal-to-methanol is an important part of coal chemical projects. Coal-to-methanol can minimize the contradiction between the development of China's chemical industry and the...
