VOC purification treatment - noble metal catalysts - environmental catalysts
随着社会高速发展的经济建设和城市化建设，环境污染与防治问题越来越受到人们的关注，环境污染问题日益严重，人们面临最基本的问题：大气污染和水污染。对于这样的现象人们也在不断研究着治理方法和措施，而催化剂在全球环境问题上起着至关重要的作用：
Shaanxi Kaida Chemical Co., Ltd. has been specializing in the research and development of precious metal catalysts for 20 years. The catalysts are used in various industries such as chemical industry, medicine, environmental protection, military, papermaking, food, etc. Recently, Shaanxi Kaida precious metal catalysts are mostly used in environmental protection industries, including VOC waste gas treatment in paint, enameled wire, coating, oven and other industries, and removal of flammable gases.
Palladium Pd, platinum Pt and other catalysts from Kaida, Shaanxi are all used for the oxidation removal of VOCs. VOCs undergo complete oxidation reaction and finally are completely oxidized to harmless CO2And H2O. Oxygen is adsorbed on the surface of the catalyst in free chemical form and reacts with non-oxides of organic compounds. After contacting with non-oxides of CO or organic compounds, the reaction forms a gaseous stateCO2And gaseous H2O. In the absence of a catalyst, a high temperature of 600-700 degrees Celsius is required and a sufficient contact time is guaranteed to carry out the reaction, while in the presence of a catalyst, 100-350 degrees Celsius, the 0.1-0 reaction can be carried out, because it is a low temperature reaction, almost no nitrogen oxides are generated, precious metal catalysts have long life and high activity, and can completely oxidize and purify the exhaust gas generated by the large use of organic solvents in paint factories, printing plants, etc.
