Core Viewpoint - China Petroleum & Chemical Corporation (Sinopec) and Sinopec Petroleum Chemical Research Institute have applied for a patent related to a method for preparing phosphorus-containing Beta zeolite, indicating a focus on innovation in chemical processes and materials [1][2]. Group 1: Patent Application Details - The patent application, titled "A Method for Preparing Phosphorus-Containing Beta Zeolite and the Prepared Zeolite," was published under CN119898795A with an application date of October 2023 [1]. - The method involves several steps: mixing phosphorus source, template agent, aluminum source, water, and optional alkali source to create a first mixture; contacting a silicon source with the first mixture to form a second mixture; and subjecting the second mixture to hydrothermal crystallization followed by thermal treatment [1]. - This method allows for the production of phosphorus-containing Beta zeolite without using fluorinated compounds, achieving a wide range of silicon-aluminum ratios and larger crystal sizes [1]. Group 2: Company Background - China Petroleum & Chemical Corporation was established in 2000, located in Beijing, and primarily engages in the petroleum, coal, and other fuel processing industries, with a registered capital of approximately 12.17 billion RMB [1]. - The company has invested in 256 enterprises, participated in 5,000 bidding projects, and holds 5000 patent records along with 45 trademark records [1]. - Sinopec Petroleum Chemical Research Institute, founded in 2022 and also based in Beijing, focuses on research and experimental development with a registered capital of 300 million RMB [2]. - The research institute has invested in 2 enterprises, participated in 994 bidding projects, and holds 1194 patent records [2].
