Problems solved by technology

In order to solve this problem, the existing method generally adopts the method of hydrogenation refining of gasoline and diesel. The existing problems are that the cost of the required catalyst is high, the catalytic efficiency is low, and it is easy to deactivate, and hydrogen of higher purity is required in the refining process. ; In addition, the existing catalysts can only reduce one of sulfur, nitrogen or aromatic compounds in the refining process, but cannot reduce the content of the three substances at the same time

Abstract

The invention relates to a novel load type diesel hydrotreating catalyst and application thereof. According to the technical scheme, a metallic element and nano Fe2P are loaded onto an oxide carrier, wherein the oxide carrier is SiO2-TiO2-Al2O3 ternary oxide carrier, and the metallic element is one or a mixture of at least more than two in Mo, Co, Ni, Pt and Pd. The novel load type diesel hydrotreating catalyst has a mesopore (1-40nm) structure in microscopic view, and not only is high in hydrodesulfurization (HDS) activity and high in hydrodenitrification (HDN) activity in the aspect of diesel hydrofining, but also is high in activity in the aspect of hydrogenation saturation (HDA) of aromatic hydrocarbon. The novel load type diesel hydrotreating catalyst has the advantages that the operation is simple, and the technological conditions needed by the novel load type diesel hydrotreating catalyst are milder than original technological conditions.

Description

technical field [0001] The invention belongs to the field of diesel catalysts, and in particular relates to a novel load-type diesel hydrotreating catalyst and its application in a hydrogenation process. Background technique [0002] In recent years, with the development of diesel engine technology, especially the application of EFI technology, the demand for diesel in countries around the world is increasing. According to statistics, from 1990 to 1999, the annual growth rate of diesel in the world reached 7.9%. Above, but a series of problems have also appeared while the demand for diesel oil is increasing rapidly, the most typical of which is the urban air pollution caused by automobile exhaust. [0003] For this reason, various countries have successively introduced new standards for diesel oil to limit the content of irrational components in diesel oil. The introduction of new standards has made the world's oil refining industry face the severe test of needing to produce...
