Abstract

The invention discloses a catalyst for a hydrogenation regeneration process of waste mineral oil. The catalyst is characterized in that the catalyst is prepared from active components W and Ni and auxiliary components P and Si which are supported by aluminum oxide carriers, and specifically, the catalyst is prepared from, by total mass, 20%-28% of WO3, 7.0%-13.0% of NiO, 4.0%-10.5% of P, 3.0%-6.0% of Si and the balance of the aluminum oxide carriers; the catalyst has the specific surface area of 220-230 m<2> / g and the pore volume of 0.52-0.56 ml / g. According to the catalyst for the hydrogenation regeneration process of the waste mineral oil, the W and Ni double-component metal combination in a specific proportion is taken as the active component and matched with the auxiliary components including Si and P, and higher hydrogenation catalytic activity and selectivity are acquired through selection and reasonable proportioning of the components. Particularly, with the introduction of the auxiliaries Si and P, the specific surface area and the acidity of the carriers are increased, the dispersity of active metal is improved, the catalyst has super-high specific surface area, large pore diameter, weak acidity and can be used for hydrogenation of whole fraction of non-mineral oil.

Description

technical field [0001] The invention relates to a catalyst used in the process of hydrogenation regeneration of waste mineral oil, and also relates to a production method of the catalyst used in the process of hydrogenation regeneration of waste mineral oil, which belongs to the field of lubricating oil preparation. 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. The recovery rate of waste lubricating oil can reach more than 90%, most of which 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, ...
