摘要/Abstract

摘要： 煤-油共炼微纳米复合催化剂于2021年4月在延长石油集团油煤新技术开发公司450 kt/a煤油共炼工业装置上成功应用。标定结果表明，以减压渣油和榆林魏墙煤为原料，在煤浆含量（w）为26.87%、压力为20 MPa、温度为466 ℃、氢/油煤浆比为1 500 m³/t、催化剂加入量（w）为0.66%的工况下，装置运行平稳，煤转化率为90.16%，轻油收率为68.51%，总油（小于360 ℃馏分）收率为76.86%，石脑油、柴油产品的硫、氮质量分数远低于10 μg/g，各项指标均达预期目标，表明该催化剂性能优异。

Abstract: The micro-nano composite catalyst for coal-oil co-processing was successfully applied in the world's first set of coal-oil co-processing unit with a capacity of 450 kt/a in Oil and Coal New Technology Development Company of Yanchang Petroleum Group Co., Ltd. in April 2021. The results of calibration showed that the vacuum residue and Weiqiang coal in Yulin were used as raw materials, under the working conditions of coal slurry content of 26.87%(w), reaction pressure of 20 MPa, reaction temperature of 466 ℃, hydrogen-to-slurry ratio of 1 500 m³/t and catalyst dosage of 0.66%(w), the unit operated smoothly, and coal conversion was 90.16% with the light oil yield of 68.51% and total oil yield (<360 ℃ fraction)of 76.86%, respectively. In addition, the contents of sulfur and nitrogen in naphtha and diesel products were lower than 10 μg/g, and all results could meet or exceed the expected targets, which demonstrated that the catalyst had excellent reaction performance.
