【摘要】 研制出一种新型的Cr-Mo-Al₂O₃粗苯加氢精制催化剂,可在较低的反应温度（550℃）条件下制出高纯度苯。其纯度≥99.9%,凝固点>5.4℃,噻吩含量<0.5ppm。此催化剂在30立升反应器中的放大试验表明,活性及稳定性良好。更多还原

【Abstract】 A catalyst （Cr-Mo-Al₂O₃） for catalytic hydrofing to produce high purity benzene from cokeoven crude benzene is developed.The catalyst can be used in comparatively lower temperature （550℃） producing high purity benzene. The purity of product benzene is 99.9%, freezing point 5.4℃ or higher and thiophene content less than 0.5 ppm.After over 1040 hours long running test in pilot plant, the experimental results indicate that both activity and stability of the catalyst are satisfactory.更多还原
