Study on Activated Carbon Adsorption of VOCs

摘要

Toluene, methyl ethyl phthalate amines, methyl ethyl ketone and ethyl acetate are used in China more vinegar several solvents, in the course will emit large amounts of volatile organic gases, serious harm to human health and the environment, it must be recycled or disposed of these gases. In this paper, for several different boiling organic gases: toluene, methyl ethyl phthalate amines, methyl ethyl ketone and ethyl vinegar to study adsorption, desorption and condensation recovery process as well as the law, in order to obtain activated carbon adsorption of pollutants on different boiling points and basic data desorption process, provide a reliable basis for the industrial design of adsorption and desorption processes. Highlights of this paper is to determine the temperature of the adsorption isotherm, domestic normal temperature adsorption studied more, and relatively few of the high temperature adsorption studies, but the adsorption capacity of the activated carbon at high temperature desorption or regeneration of important guiding significance.
