摘　　要：选用宁夏煤业公司煤炭间接液化柴油(间接液化柴油)、中国石油天然气股份有限公司化石柴油(中石油柴油)和中国神华煤制油化工有限公司煤炭直接液化柴油(直接液化柴油)为实验燃料,分别在发动机转速为1 200、1 400、1 700、2 000 r/min条件下对比考察了燃用3种柴油后CO、HC、NO和烟度等的排放特性。结果表明:燃用间接液化柴油时,污染物CO排放量最低;与中石油柴油相比,燃用间接液化柴油NO、HC排放量略低,但在转速为2 000 r/min的中低负荷下,燃用间接液化柴油的HC排放量比中石油柴油略高;在上述4个转速条件下,燃用间接液化柴油CO排放量平均下降率为30%左右;HC排放量平均下降率为24%左右;NO排放量平均下降率为12%左右;烟度平均上升率为4%左右。综上所述,燃用间接液化柴油具有良好的环保性。Using coal indirect liquefied diesel,PetroChina diesel,and coal direct liquefied diesel as experimental fuels,the emission characteristics of CO,HC,NO and smoke after burning these three diesels at speeds of 1,200 r/min,1,400 r/min,1,700 r/min and 2,000 r/min are investigated respectively.The results show that the emission of CO is the lowest when burning coal indirect liquefied diesel;compared with PetroChina diesel,NO and HC emissions of coal indirect liquefied diesel are slightly lower,but indirect liquefied diesel has slightly higher HC emissions than PetroChina diesel at low-medium load at a speed of 2,000 r/min;at these four rotation speeds,the average reduction rate of CO emissions from indirect liquefied diesel is about 30%,the average reduction rate of HC emissions is about 24%,the average reduction rate of NO emissions is about 12%,and the average increase rate of smoke emissions is about 4%.In conclusion,coal indirect liquefied diesel has better environmental friendliness.
