Case study of VOC catalyst in chemical industry waste gas treatment

Chemical industry in the production process will produce a lot of industrial waste gas, which contains volatile organic compounds (VOC), such as benzene, formaldehyde, toluene and so on. These substances are not only harmful to human health, long-term exposure may cause respiratory diseases and even cancer, but also pollute the atmospheric environment, form ozone and haze, and aggravate global warming. Therefore, how to efficiently deal with VOC in the exhaust gas of the chemical industry has become an important topic in the field of environmental protection.
A VOC catalyst is a material capable of converting harmful VOCs into harmless substances such as carbon dioxide and water. It achieves exhaust gas purification by accelerating chemical reactions and decomposing VOC at lower temperatures. Here is an analysis of a practical case:
A chemical plant emits a lot of waste gas containing benzene in the production process. Benzene is a strong carcinogen, which is harmful to the environment and human body. In order to solve this problem, the plant adopts VOC catalytic oxidation technology, and the core equipment is a reactor equipped with VOC catalyst. The waste gas enters the reactor after preheating, and under the action of the catalyst, benzene is oxidized to carbon dioxide and water at a temperature of about 300℃, and the purification efficiency reaches more than 95%.
The VOC catalyst used in this case is mainly composed of precious metals (such as platinum, palladium) and transition metal oxides (such as manganese, copper), and has the following advantages:
High efficiency: The catalyst can quickly decompose VOC at lower temperatures, saving energy.
Stability: It can still maintain high activity and long service life in complex industrial exhaust gas environment.
Environmental protection: the VOC is converted into harmless substances, no secondary pollution.
In the future, with the continuous progress of catalyst technology, VOC treatment efficiency will be further improved, providing stronger support for the green development and environmental protection of the chemical industry.
