The invention belongs to the field of petrochemical engineering, and relates to a novel method for removing non-alkaline nitrogen-indole in an oil product through ionic liquid. The novel method is characterized in that SO3H-containing functionalized acidic ionic liquid is used as a catalyst and a solvent, and the operation can be carried out at lower temperature (20 to 70 DEG C); and after the reaction, the recovered ionic liquid can be reused by being simply treated. Compared with the conventional method, the novel method provided by the invention has following characteristics that (1) the conventional strong acid nitrogen removal and hydrogenation nitrogen removal in the background technology are not needed, so that the problems due to the corrosion of the equipment, the wastewater drainage, and the high price of equipment, can be greatly reduced; (2) the adopted ionic liquid is the water-soluble ionic liquid which can be layered well respect to a simulated oil product after being dissolved by water in a certain proportion, and thus the convenience is provided for the separation after the nitrogen removal treatment; and (3) the implemented liquid nitrogen removal method is mild in condition, the operation is simple and easy to carry out, the ionic liquid can be reused, and the problem in the background technology that the catalyst cannot be recycled can be avoided.
Description
technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a new method for removing non-basic nitrogen-indole in oil products by using ionic liquid as a catalyst and a solvent. technical background [0002] The existence of nitrogen compounds in the oil will not only affect the color and stability of the oil; after combustion, nitrogen oxides NO X In addition to causing serious air pollution, it will also have a great impact on the reduction of sulfur content in gasoline and diesel. In the production of oil products, a very small amount of organic nitrogen compounds can cause poisoning of precious catalysts in catalytic cracking, hydrofining and other processes, shorten the service life of catalysts, thereby increasing production costs and reducing output. According to statistics, if the nitrogen content in crude oil is reduced by 90%, the output of gasoline can be increased by 20%. Studies have shown that indole, one of the nitrog...
