  • Patent number: 12145137
    Abstract: A DLM-1 molecular sieve, a process for preparing the molecular sieve, and use thereof in treating an organic substance are provided. The DLM-1 molecular sieve is an Al-SBA-15 molecular sieve, and has a schematic chemical composition as represented by the formula “first oxide*second oxide”. The first oxide is silica, the second oxide is alumina, and the content by mass percent of alumina in the schematic chemical composition is 2% to 85%. The DLM-1 molecular sieve is suitable for the hydrodenitrogenation reaction of heavy distillate oil, and is favorable for improving the hydrodenitrogenation activity.

  • Patent number: 11779909
    Abstract: Disclosed is a hydrocracking catalyst, a preparation method and an application thereof. The catalyst comprises a carrier, silicon dioxide and active ingredients loaded on the carrier, wherein the carrier comprises Y molecular sieves and SAPO-34 molecular sieves. The preparation method of the hydrocracking catalyst comprises the following steps: (1) mixing materials comprising Y molecular sieves and SAPO-34 molecular sieves, and then subjecting the mixture to molding, drying and calcinating to obtain a carrier; (2) introducing silane and the active ingredients into the carrier prepared in the step (1), subsequently performing the drying and calcinating to prepare the hydrocracking catalyst. The catalyst prepared with the method can be used for hydrocracking reaction, thereby significantly increase yield of jet fuel.
