Description

technical field [0001] The invention relates to a gas adsorption and desorption evaluation technology in the field of energy and chemical industry, in particular to a multi-component low-carbon hydrocarbon adsorption and desorption evaluation device and method. Background technique [0002] Volatile organic compounds (VOCs) refer to the general term for organic compounds with a boiling point of less than 260°C under a standard atmospheric pressure of 101.3kPa (20), including aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, oxygen-containing hydrocarbons, nitrogen-containing hydrocarbons and sulfur-containing hydrocarbons. Hydrocarbons etc. In many chemical production, the emission of VOC-containing waste gas has always been a very prominent problem. Its emission will not only cause serious air pollution, but also greatly waste resources and increase production costs. [0003] In the energy and chemical industry, there are light hydrocarbon volatile o...
