Special activated carbon for VOCs treatment
VOCs is the abbreviation of Volatile Organic Compounds, derived from the acronym of Volatile Organic Compounds 3 words, s means a variety of mixtures, it is a type of organic matter that exists in the air in the form of steam.
Different organizations have slightly different definitions of VOCs. For example, VOCs defined by the U.S. Environmental Protection Agency (EPA) refer to any carbon-containing organic matter that participates in atmospheric photochemical reactions except for CO, CO2, H2CO3, metal carbides, metal carbonates and ammonium carbonate. . The World Health Organization (WHO) defines VOCs as organic compounds with a boiling point of 50-250°C, a saturated vapor pressure of more than 133.2 Pa at room temperature, and a type of organic matter that exists in the air in the form of vapor at room temperature. From the above definition, EPA does not limit the initial boiling point. It emphasizes the type of VOCs that participate in photochemical reactions, that is, the type of VOCs that will cause harm. For those that do not participate in atmospheric photochemical reactions, they are called exempt solvents, such as acetone and tetrachloroethane. It is mainly defined from the perspective of environmental protection; and the WHO defines the starting point from VOCs under what conditions, and specifies the boiling point, regardless of whether it participates in atmospheric photochemical reactions.
