According to data from the Tianyancha app, Sinopec (600028) has newly obtained an invention patent grant. The title of the patent is “Method, Device, Apparatus, and Storage Medium for Characterizing the Pore Size Distribution of Solid Materials”; the patent application number is CN202111251650.X, and the grant date is August 1, 2025. Patent Abstract: The present invention discloses a method, apparatus, device, and storage medium for characterizing the pore size distribution of solid materials, which includes the step of obtaining raw data generated by physical nitrogen adsorption tests on the solid materials ； Identify the target data from the raw data and generate valid data ； Using the X-axis and Y-axis data of each element as the point coordinates, an aperture distribution diagram is generated based on the valid data ； Generate auxiliary data by adding auxiliary elements to the valid data ； Generate characterization data corresponding to the pore size distribution diagram, including: determining each target peak based on the peak height values obtained from the valid data ； Determine the left and right boundaries of each target peak based on the auxiliary data respectively ； Calculate the proportion of each target peak among all target peaks based on the valid data ； This invention enables the rapid generation of characteristic data such as the proportion of each peak among all peaks while plotting the pore size distribution diagram of solid materials, thereby improving the efficiency and effectiveness of producing information data on pore size distribution.
