Problems solved by technology

In the current waste lubricating oil regeneration process, the hydrogenation catalyst used is an ordinary oil hydrogenation catalyst. Due to the particularity of the waste lubricating oil components, it is difficult to achieve the ideal hydrogenation catalyst when the existing ordinary hydrogenation catalyst is used to recycle waste lubricating oil. Hydrogen refining effect

Abstract

The invention relates to a used lube oil hydrogenation catalyst and the preparing method. The catalyst is formed as the alumina is used as the carrier to carry active components W, Ni and assistant agent component P. The catalyst comprises 25%-35% of WO3 by wt, 2.0-7.0% of NiO by wt, 2.0%-5.5% of P by wt and other is alumina carrier. The catalyst is provided with high pore capacity and high surface area. Under the softer medium-pressure condition, impurities such as S, N, O and heavy metal so on in used lube oil is eliminated in large space velocity.

Description

technical field [0001] The invention relates to a hydrogenation catalyst and a preparation method thereof, in particular to a catalyst which can be used for hydrogenation reaction in the regeneration treatment process of waste lubricating oil and a preparation method thereof. Background technique [0002] With the continuous rapid growth of China's economy, the consumption of lubricating oil products is also increasing year by year. In 2006, the apparent consumption of lubricating oil in my country was about 6.8 million tons, and correspondingly, about 4 million tons of waste lubricating oil will be produced. And the recovery rate of waste lubricating oil can reach more than 90%, and most of them are used as fire oil, which not only pollutes the environment, but also wastes energy. [0003] With the continuous rise of crude oil prices and the dwindling of petroleum resources, the regeneration of waste oil has attracted increasing attention, especially the recycling and reuse...
