渣油加氢脱硫催化剂RMS-30的开发及其工业应用

制备了孔分布集中的氧化铝载体，并以饱和浸渍法制备了CoMo/Al2O3催化剂，考察了Co/(Co+Mo)原子比和助剂对催化剂加氢脱硫活性及表面性质的影响。结果表明：当Co/(Co+Mo)原子比为0.3左右时，催化剂的加氢脱硫活性最好；催化剂中引入适量的助剂，可以提高CoMo/Al2O3催化剂的活性。在此基础上研制出具有高加氢脱硫活性的RMS-30催化剂。中型装置评价及工业应用结果表明，与上一代渣油加氢脱硫催化剂相比，RMS-30催化剂具有更好的脱硫和脱残炭性能。

DEVELOPMENT AND COMMERCIAL APPLICATION OF NEW RESIDUE HYDRODESULFURIZATION CATALYST RMS-30

An alumina carrier with more concentrated pore size distribution was fabricated, and CoMo/Al2O3 catalysts were prepared by wet impregnation method base on the carrier. The effect of nCo/n(Co+Mo) atomic ratio and promoter on catalyst activity was evaluated. The HDS test results reveal that the catalyst with nCo/n(Co+Mo) of 0.3 possesses the best hydrodesulfurization activity and that introduction of promoter into the catalyst can improve the activity of CoMo/Al2O3 catalysts. Based on these results, RMS-30 catalyst with high hydrodesulfurization activity was developed. The pilot plant results show that the relative hydrodesulfurization activity of RMS-30 catalyst increases by more than 20% compared with the previous generation of residue hydrodesulfurization catalyst RMS-1B. The commercial results also prove the better performance of RMS-30 in terms of removal of sulfur and carbon residue.
