Abstract

The invention relates to an adsorbent for adsorption of VOCs and a preparation method of the adsorbent. The preparation method includes the steps that a silicon source, an aluminum source and a template are mixed at a set proportion and self-pressed and crystallized under the set temperature and the set pressure, and a first adsorbent precursor for the VOCs is produced; the first adsorbent precursor for the VOCs is washed, ion-exchanged and then roasted, and a second adsorbent precursor for the VOCs is obtained; and the obtained second adsorbent precursor for the VOCs is mixed with aluminum oxide, the mixture is mixed with water, extruded and dried and roasted, and the adsorption for the VOCs is obtained. The adsorbent for the VOCs synthesized from cheap raw materials has the advantages ofthe good hydrothermal stability, the high crystallinity degree, the large surface area and the moderate pore diameter, and is suitable for adsorption of gas of the VOCs.

Description

technical field

[0001] The disclosure relates to an adsorbent for VOCs adsorption and a preparation method. Background technique

[0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art.

[0003] Volatile organic compounds (VOCs) refer to organic compounds with a saturated vapor pressure greater than 133.32Pa at normal temperature, a boiling point below 50-260°C at a standard atmospheric pressure of 101.3kPa and an initial boiling point equal to 250°C, or any organic compound that can volatilize at normal temperature and pressure. organic solid or liquid.

[0004] A large amount of VOCs emissions will destroy the ozone layer in the atmosphere on the one hand, leading to the generation of photochemical smog....
