废塑料油加氢精制的研究

Research on Hydrogenation Refining of Waste Plastic Oil

实验以废塑料油为原料,在Zr/γ-Al2O3-HY催化剂的作用下进行加氢精制反应,探究了反应温度、压力、空速以及氢油比等因素对加氢精制效果的影响。实验表明,加氢精制效果最佳条件为:反应温度为210℃、反应压力为6.0 MPa、空速0.5 h-1以及氢油比为800:1。柴油收率为83.0%。加氢后得到的柴油凝点为-12℃,色度为1.0,闪点为54.2,十六烷值为53.7。

Waste plastic oil was hydrogenated in the presence of Zr/y-Al2O3-HY catalyst.Effect of reaction temperature, pressure, space velocity and hydrogen to oil ratio on hydrotreating effect was investigated. Experimental results show that the optimal reaction conditions are as follows： refining temperature 210 ℃, pressure 6.0 MPa, space velocity 0.5 h-1 and hydrogen to oil ratio 800：1. Under above conditions, the diesel yield can reach to 83.0%. After hydrogenated, the solidifying point of diesel is -12 ℃, the chroma is 1.0, the flash point is 54.2 and the cetane number is 53.7.
