  • Silicon-and germanium-based SCM-25 molecular sieve, preparation process and use thereof
    Patent number: 11952283
    Abstract: A silicon-and germanium-based molecular sieve has a framework chemical composition as represented by the formula “SiO2.1/nGeO2”. The silicon/germanium molar ratio is 0.1n30. The molecular sieve has a unique X-ray diffraction pattern. It can be used in adsorptive separation, ion exchange, and catalytic conversion of organic compounds.

  • PREPARATION METHOD OF REPRESENTATIVE DEGASSED OIL WITH EQUIVALENT MINIMUM MISCIBLE PRESSURE
    Publication number: 20230366869
    Abstract: A Hydrophilic-Lipophilic Deviation theory-based method is provided to prepare representative degassed oil with equivalent minimum miscible pressure to live oil. The method can reduce the number of trial and error type experiments during the representative degassed oil preparation process by measuring the MMP and EACN for dead and live oil. The representative degassed oil formulation could be easily predicted after determining the required MMP and EACN values. The prepared oil can reflect the key mechanism of multiple contact miscible mechanism in the process of gas flooding more accurately. It allows experiments that are inconvenient to use live oil to consider the mechanism of multiple contact miscibility easily.
