This is just a starting point; more participation will make things more lively. The forum becomes even better with your presence; we welcome everyone to engage more in discussions here. It’s hot in July, so be careful to prevent fires. —— Reported by China Chemical Industry News. Recently, the \"non-precious metal catalyst for the catalytic combustion of volatile organic compounds (VOCs) and carbon monoxide (CO)\", developed by Sinopec Research Institute of Petroleum Processing Co., Ltd. (hereinafter referred to as the Research Institute), passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. 　　The evaluation committee believes that the integrated catalyst RCO-1, developed based on doped transition metal oxide catalytic materials, offers advantages such as low cost, high activity, and good stability in the fields of VOCs and CO catalytic combustion. It can serve as an effective alternative to precious metal catalysts, providing technical support for enterprises to reduce costs and improve efficiency. 　　The project team’s lead researcher explained that there are three innovative aspects to the technical achievements. First, the redox capacity of transition metal oxide catalytic materials was improved through doping modification. Second, a hydrophobic and sulfur-resistant modification technique was developed to enhance the water and sulfur resistance of the catalysts. Third, a new slurry formula was invented, which reduced the shedding rate of the catalytic material and improved the structural stability of the integral catalyst. 　　The team collaborated with a catalyst company to complete the pilot-scale production of the RCO-1 catalyst, and carried out 1,000 hours of industrial pilot tests for the catalytic combustion of VOCs and CO. Test data show that the RCO-1 catalyst achieves a conversion rate of over 98% for VOCs and CO; after purification, the CO level is below 200 milligrams per cubic meter, and the VOCs level at the outlet is below 1.0 milligrams per cubic meter – all of which meet the requirements of **emission regulations. To date, the project has filed 12 Chinese invention patents, of which 8 have been granted, granting it independent intellectual property rights. 　　Currently, the main challenges in the field of catalytic combustion of industrial exhaust gases are reducing the cost of catalysts and improving their catalytic efficiency. The non-precious metal catalysts developed by the Institute of Rock Mechanics are suitable for recovering VOCs of low value from the exhaust gases of petrochemical enterprises, as well as for treating high-concentration CO waste gases from sintering processes. Compared with precious metal catalysts, they offer excellent cost efficiency and high treatment efficiency. (Peng Yan)
