On April 4, 2025, according to information from the National Intellectual Property Administration, China Petrochemical Corporation has applied for a patent titled “Catalyst Protector with Synergistic Effects, and Methods for Its Preparation and Applications,” with publication number CN 119746943 A and an application date of September 2023.

　　The patent abstract indicates that the present invention relates to a catalyst protector with synergistic effects, as well as a method for preparing this catalyst protector and its application in exhaust gas treatment. The invention produces an integral honeycomb catalyst protector by kneading, mud‑rolling, extruding, drying, and calcining a carrier component containing Si, Al, and optionally Mg, along with lubricants, foaming agents, binders, metal oxides, and water. This preparation method is simple, results in a more cost‑effective product with superior stability, and enables synergistic interaction with the catalyst, thereby preventing catalyst deactivation, extending catalyst life, enhancing purification efficiency, and broadening the scope of catalyst applications. It addresses the current market challenges posed by expensive catalyst protectors, short service lives, susceptibility to leakage, and limited functionality.

　　According to data from Tianyancha, China Petrochemical Corporation was founded in 2000 and is headquartered in Beijing. The company primarily engages in the processing of petroleum, coal, and other fuels.
