Abstract

The invention relates to the technical field of waste gas treatment, in particular to a novel VOCs absorbent and a preparation method thereof. The novel VOCs absorbent is prepared from, by weight, 50-80 parts of biodiesel, 8-30 parts of a non-ionic surfactant, 4-15 parts of a cosurfactant, 0.5-5 parts of camphene, 4-12 parts of 1-butyl-3-methylimidazolium hexafluorophosphate, 3-8 parts of 1-butyl-3-methylimidazolium tetrafluoroborate and an appropriate amount of water. The prepared novel absorbent has high absorption efficiency for low-concentration organic waste gas, and the absorbent after waste gas treatment can be directly used as fuel for combustion, and the environmental and economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a novel VOCs absorbent and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economic level, industries such as petrochemical, printing coatings and electronics have developed rapidly, and the environmental pollution problems brought about have become more and more serious. Among them, the development of industrial industries will produce a large amount of volatile organic compounds (Volatile Organic Compounds, VOCs) emissions, which will not only pose a great threat to human health and the environment, but also VOCs will destroy the ozone layer and carry out pollution in the troposphere and stratosphere. Atmospheric photochemical reactions generate acidic substances, atmospheric particulate matter (PM2.5) and ozone (O 3 ) and other secondary pollutants, while PM2.5 and O 3 It is the main cause of...
