Abstract

The invention discloses a novel process of utilizing blast furnace titanium slag for adsorbing and regenerating waste lubricating oil. The process is characterized by comprising the steps of crushing, grinding and screening the blast furnace titanium slag, then adding the blast furnace titanium slag into an adsorption and regeneration reactor filled with the waste lubricating oil, stirring the waste lubricating oil with a stirrer, making the waste lubricating oil be subjected to an adsorption and regeneration reaction at the reaction temperature of 80-120 DEG C filtering the blast furnace titanium slag after the reaction is ended, and obtaining regenerated lubricating oil. The novel process is simple in process condition, little in investment, lower in operation cost and capable of effectively lowering cost of adsorption and regeneration of the waste lubricating oil. Meanwhile, activity of TiO<2> in the blast furnace titanium slag is utilized, blast furnace titanium slag serves as adsorbent, adsorption and regeneration of the waste lubricating oil are conducted, high added-value utilization of the blast furnace titanium slag can be achieved, and social benefits and economic benefits are fairly remarkable.

Description

technical field [0001] This patent belongs to the technical field of comprehensive utilization of vanadium-titanium magnetite, and is a new 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 bla...
