以辽河石化焦化蜡油对象,对甲酸精制、乙醇-FeCl3络合、白土吸附、硅胶氧化铝吸附、沸石吸附以及糠醛精制等非加氢脱碱氮技术进行了筛选和评价。研究表明,甲酸精制对焦化蜡油中碱氮的脱除效果显著,剂油比在1∶7时就能使碱氮从1766 mg/kg降至800 mg/kg以下,蜡油收率95%以上;FeCl3的络合作用有利于碱氮的脱除,但乙醇-FeCl3的脱氮效果并不明显,白土、硅胶氧化铝、沸石等吸附脱碱氮效果不佳;糠醛萃取也可将辽河石化蜡油中的碱氮脱至800 mg/kg以下,尽管抽余油收率相对较低（70%左右）,但抽出油可作为化工原料使用,在经济成本及技术可行性上由于甲酸精制。

Non-hydrogenation basic nitrogen removal technologies of methanoic acid refining,ethanol-FeCl3 complexation,adsorption by carclazyte,silica gel-aluminum oxide and zeolite,and furfural treatment for coker gas oil were evaluated.During the methanoic acid refining test,the basic nitrogen was decreased from 1766 mg/kg to below 800 mg/kg only at the acid oil ratio of 1：7,and the oil recovery was obtained over 95%.The complexing action of FeCl3 provided a good favor on basic nitrogen removal,but the ethanol-FeCl3 complexation performed poor.Neither of the carclazyte,silica gel-aluminum oxide or zeolite adsorption proved accepted ability on basic nitrogen removal.Furfural treatment also decreased the basic nitrogen content to below 800 mg/kg.Although the oil recovery was relatively not high（about 70%）,the raffinate oil was valuable as chemical raw materials,and the economic cost and the technical feasibility was better than that of methanoic acid refining.
