Abstract

The invention discloses a process for using blast furnace titanium slag to absorb and regenerate waste lubricating oil. The adsorption and regeneration reaction of the waste lubricating oil is carried out under the reaction temperature of 120° C. to 120° C. under the agitation of the stirrer. After the reaction is completed, the blast furnace titanium slag is filtered to obtain the regenerated lubricating oil. The invention has simple process conditions, less investment and lower operating cost, and can effectively reduce the cost of adsorption and regeneration of waste lubricating oil. At the same time, using the activity of TiO2 in blast furnace titanium slag and using blast furnace titanium slag as an adsorbent to carry out adsorption and regeneration of waste lubricating oil can realize high value-added utilization of blast furnace titanium slag, and the social and economic benefits are very obvious.

Description

technical field [0001] This patent belongs to the technical field of comprehensive utilization of vanadium-titanium magnetite, and is a process for comprehensive utilization of blast furnace titanium slag produced by blast furnace smelting vanadium-titanium magnetite. Background technique [0002] my country is rich in vanadium-titanium magnetite resources, with proven reserves of 9.83 billion tons and prospective reserves of more than 30 billion tons. Among them, Panzhihua titanium reserves account for more than 90% of domestic proven reserves and 40% of world reserves. The smelting of vanadium-titanium magnetite and the comprehensive utilization of vanadium, titanium, especially titanium resources are of great significance to my country's reduction of foreign dependence on iron ore and the utilization of strategic precious metal resources. At present, the smelting of vanadium-titanium magnetite is mainly carried out in blast furnaces. Restricted by the fluidity of blast f...
