Core Viewpoint - China Petroleum & Chemical Corporation (Sinopec) and its subsidiaries have applied for a patent related to a method for pre-treatment of molecular sieve products, indicating ongoing innovation in the molecular sieve technology sector [1][2]. Company Overview - China Petroleum & Chemical Corporation (Sinopec) was established in 2000, located in Beijing, primarily engaged in petroleum, coal, and other fuel processing industries. The company has a registered capital of approximately 12.17 billion RMB and has invested in 254 enterprises, participated in 5,000 bidding projects, and holds 5000 patent records [1]. - Sinopec Catalyst Co., Ltd. was founded in 2013, based in Beijing, focusing on wholesale activities with a registered capital of 150 million RMB. The company has invested in 12 enterprises, participated in 2,175 bidding projects, and holds 855 patent records [2]. - Sinopec Nanjing Catalyst Co., Ltd. was also established in 2013, located in Nanjing, primarily engaged in the manufacturing of chemical raw materials and products, with a registered capital of 25 million RMB. The company has participated in 450 bidding projects and holds 60 patent records [2]. Patent Details - The patent application titled "A Method for Pre-Treatment of Molecular Sieve Products" was filed on November 2023, focusing on a method that involves pre-treating a mixture of molecular sieve raw powder and gel solvent to obtain a precursor. The process is conducted in high-speed mixing equipment with a rotor and inner cylinder speed difference of ≥5 m/s, resulting in a homogeneous and dense precursor, leading to a stable molecular sieve product with good crushing strength [1].
