　　在100 mL连续加氢固定床装置上，采用先加氢再降凝的两段工艺对纯焦化柴油生产低凝柴油条件进行了考察。在反应温度为390℃、压力为8 MPa、一反和二反的空速分别为1.5和1.8 h-1氢油比（V/V）为600︰1的条件下，所得低凝柴油的收率为66.3%(m)，凝点为-29℃，石脑油的收率为16.7%，该石脑油适合做乙烯裂解原料。

Production of low setting point diesel from pure coking diesel by the hydrofining process and pour point depression process was investigated in a 100 mL fixed-bed continuous hydrogenation reactor. The results show that when reaction temperature is 390 , pressure℃ is 8 MPa, the first reactor’s space velocity is 1.5 h-1 and the second reactor space’s velocity is 1.8 h-1 , hydrogen-oil ratio is 600:1 (V/V), the yield of low setting point diesel is 66.3%( m), freezing point is-29 , naphtha yield℃ is 16.7%and the naphtha can be used as ethylene cracking raw material.
