Sinopec has applied for a patent for a method of purifying gases containing organic pollutants, which helps to prevent the issue where such adsorbed organic pollutants remain unconverted due to reasons such as desorption. According to information from the Intellectual Property Office dated August 4, 2025, Sinopec Corporation and Sinopec (Dalian) Petrochemical Research Institute Co., Ltd. have filed a patent application titled “A Method for Purifying Gases Containing Organic Pollutants”, with the publication number CN120393692A; the application was submitted in January 2024. The patent abstract indicates that this invention discloses a method for purifying gases containing organic pollutants. The purification method includes two operating modes: the first mode is the adsorption purification mode, while the second mode is the in-situ catalytic oxidation mode. In the second mode, the oxygen concentration inside the reactor is controlled, and the bed temperature control system is activated to heat both the adsorption oxidant bed and the catalytic oxidation catalyst bed until the reaction start temperature is reached. Thereafter, by gradually heating and controlling the temperatures of these beds, the purified gas resulting from the reaction is continuously removed from the reactor, after which the bed temperature is adjusted to switch back to the first operating mode. When the method of the present invention is used to treat gases containing organic pollutants, it enables effective control of the temperature in the reaction zone through efficient heat exchange, thereby ensuring the intrinsically safe operation of the reactor and facilitating in-situ adsorption and oxidation reactions. This approach effectively prevents the issue of the adsorbed organic pollutants not being converted due to desorption or other reasons, resulting in good purification effects.
