Abstract

The invention discloses a used lubricating oil complete hydrogenation type regenerated catalyst and a preparation method and application thereof. The catalyst comprises catalyst carrier and active components, wherein the active components are WO3, NiO and assistant Si; WO3 accounts for 28-38% of the total weight of the catalyst, NiO accounts for 4-8%, Si accounts for 2-3%, and the balance is Al2O3 carrier; and the specific surface area of the catalyst is 230-265m<2> / g, and the pore volume is 0.47-0.55ml / g. The preparation method of the invention uses the characteristics of used lubricating oil, selects W-Ni metal in a certain proportion as active component, combines with assistant Si and selects various components and reasonable proportioning to prepare the catalyst with higher hydrogenation activity and selectivity. The catalyst has ultrahigh specific surface area, large pore diameter and properties of weak acid, is used to perform hydrogenation to the full-range components of used lubricating oil, has strong ability of removing S, N and O and performing hydrosaturation of unideal components and has extremely high demetalization and metal resistance.

Description

1. Technical field [0001] The invention belongs to the technical field of catalysts, and in particular relates to a waste lubricating oil full-hydrogenation regenerated catalyst and its preparation method and application. 2. Background technology [0002] With the requirements of environmental protection and energy saving, automobiles and industrial machinery processing equipment need high-quality lubricating oil. In order to prepare high-grade lubricating oil products, high-quality lubricating oil base oil must be used. Before the 1990s, my country's lubricating oil production was completely based on the old three sets of processing technologies. Although the speed of refinery transformation has accelerated in recent years, my country's hydrogenation production of Group II and III base oils only accounts for about 20% of the total production capacity. However, the market demand for hydrotreated and isomerized dewaxed base oils has reached about 30%, which is far from meetin...
