Abstract
Description
technical field
[0001] The invention relates to a catalyst, in particular to an optimized diesel hydrocracking catalyst and a preparation method thereof. Background technique
[0002] Hydrocracking is a very important technology for the efficient conversion of heavy oil and the production of clean oil products in the oil refining industry. It can process heavy crude oil with high sulfur and high metals. It has a wide source of raw materials, high production flexibility, good product quality and middle distillate Features such as high oil yield. Hydrocracking technology can directly produce low-aromatic, low-sulfur and low-nitrogen high-quality middle distillate products from vacuum diesel oil (VGO), which can meet increasingly stringent environmental protection requirements, and the catalyst plays a central role in the hydrocracking reaction. The key to hydrocracking technology lies in the development and improvement of catalysts.
