Scope

Scope: This standard specifies the terms and definitions, technical principles, technical requirements, detection methods, process design, commissioning and operation and maintenance, etc. of the room-temperature catalytic oxidation technology for controlling volatile organic compounds (VOCs). This standard applies to the room-temperature catalytic oxidation method for controlling VOCs. 3.1 Volatile Organic Compounds (VOCs): Organic compounds that participate in atmospheric photochemical reactions, or organic compounds determined according to relevant regulations. When characterizing the overall emission of VOCs, the total volatile organic compounds (expressed as TVOC) and non-methane hydrocarbons (expressed as NMHC) can be used as pollution control indicators according to industry characteristics and environmental management requirements. 3.2 Normal Temperature Catalytic Oxidation (NTCO): The room-temperature catalytic oxidation technology refers to the process in which VOCs are catalytically oxidized to harmless small molecular substances such as CO2 and H2O under normal temperature (including room temperature but not limited to room temperature), normal pressure (including standard atmospheric pressure but not limited to standard atmospheric pressure) without the need for high-temperature assistance, high-pressure discharge, or UV irradiation. 3.3 Atomic Active Sites: Different from traditional nano- and sub-nano-active sites, atomic active sites refer to clusters of single or several atoms with atomic-level dispersion as reaction active sites. 3.4 Active Oxygen Species (AOS): Active oxygen species refer to highly reactive substances generated during the electron transfer process of oxidants. Common examples include hydroxyl radicals, superoxide radicals, and singlet oxygen, etc. These primary active oxygen species can also react with other molecules to produce secondary active oxygen species, such as carbon-centered radicals. 3.5 Catalyst Poisoning: The ph
