摘　　要：为了验证专利商Axens公司推荐的加氢精制催化剂A能否满足神华煤直接液化示范工程的操作要求,在小型加氢精制装置上进行了加工煤液化油品的研究,在中型加氢稳定装置上进行了利用蒽油和洗油混合原料制备煤直接液化单元首次开车所需开工溶剂和加工煤液化油品的研究。试验结果表明,A催化剂具有良好的初活性、低温活性、及适当的脱芳碳活性,加氢精制催化剂的性能,能够满足利用蒽油和洗油制备煤直接液化单元开工用溶剂和加工煤液化油品,为煤液化生产循环供氢溶剂油的要求。In order to test whether the hydrofining catalyst A, recommended by patent holder Axens company, can meet the need of Shenhua direct coal liquefaction demonstration plant, the hydrotreatment of the liquefied products was studied in a pilot-scale hydrotreatment unit. The hydrotreatment of anthracene oil and wash oil mixture and that of liquefied products were also studied using process development unit （PDU）. The mixture of anthracene oil and wash oil after hydrotreatment was served as the starting solvent for the direct coal liquefaction process. The results showed that the catalyst A had good initial activity, low temperature activity, and proper activity of aromatic carbon removal. The catalyst A could meet the requirement of hydrotreatment of anthracene oil and wash oil mixture for starting solvent and of liquefied products, and could produce cycle solvent for direct coal liquefaction process.
