摘　　要：针对焦炉气作车用燃料苯、萘含量超标的问题,对焦炉气进行了深度脱苯脱萘处理。在焦化企业对焦炉气初步净化处理的基础上,采用轻柴油洗萘工艺对焦炉气进行进一步的脱萘处理。处理后的焦炉气中,萘的质量浓度降低至50 mg/m3以下;苯也部分溶解于轻柴油,质量浓度进一步降低到2 g/m3以下。净化后的焦炉气可满足焦炉气汽车的使用要求。Coke oven gas as an alternative fuel for motor vehicles can improve vehicle＇s impact on environment and can solve the problem of waste of fuel resources. Carbon deposition is of common occurrence due to poor combustion of benzene. On top of that, the automotive intake manifold and the gas removal of benzene and naphthalene from coke oven gas is a critical the coke oven gas from coking enterprises, light diesel oil washing nozzle are likely clogged by naphthalene. Therefore, process. In addition to the preliminary purification of has to be adopted to further remove the naphthalene and bring it down to less than 30 mg/m3-50 mg/m3, in the mean time, benzene is also partially dissolved in the light diesel oil, and the content of which is brought down to less than 2 g/m3. The engine bench test that coke oven gas, after such treatment, can meet the relevant requirements and can be used as tor vehicles. and the trial run indicated an alternative fuel for mo-
