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.

DLM-1 molecular sieve, process for preparing the same, and use thereof

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.

Hydrocracking catalyst, preparation method therefor and application thereof

This invention relates to a hydrotreating catalyst suitable for heavy distillate oil hydrodesulfurization, production and use thereof. The present hydrotreating catalyst exhibits significantly improved heavy distillate oil (deep) hydrodesulfurization activity.
