CL-03柴油深度加氢脱硫催化剂开发

Preparation of CL-03 Catalyst for Deep HDS

以Y改性载体Z-1、Z-2、Z-3担载钼镍钨活性组分,制备了深度加氢脱硫催化剂CL-01、CL-02和CL-03,并进行了相关评价对比试验。结果表明:以Z-3制备的催化剂CL-03活性最佳;与工业剂R-1相比,催化剂CL-03具有更高的脱硫氮活性,其在反应温度360℃,体积空速3 h-1,氢油比250∶1,压力4 MPa条件下的相对脱硫活性为136.9%,相对脱氮活性为147.2%。在考察范围内,催化剂CL-03脱硫率最高达99.87%,产品硫含量7.6μg·g-1,满足柴油国V的硫含量标准。

Three high performance hydrodesulphurization （HDS）catalysts CL-01, CL-02 and CL-03 were prepared by depositing Mo-Ni-W active components on Y modified cartier Z-1, Z-2 and Z-3, and a research was made about the activity of the catalysts. Results showed that catalyst CL-03 has the highest activity. Compared to the industrial catalyst R-1, the relative activities of desulfurization and denitrification of CL-03 can reached 136.9 % and 147.2 % in the condition of he reaction temperature of 360 ℃, liquid hourly space velocity of 3 h-1, hydrogen/oil volume ratio of 250, hydrogen pressure of 4.0 MPa. In the range of investigation, the desulfurization rate of CL-03 can reach 99.25 %, and the sulfur contents in the products less than 10 μg.g-1.
