  hydrotreating
It is a promising support for cracking and hydrotreating catalysts.
      
The mechanism of thiophene hydrodesulfurization over sulfide catalysts for hydrotreating and the effect of the catalyst composition and feed on the number, distribution, and performance of active sites were studied using 35S and 3H isotopes.
      
Based on the results of radioisotopic study, a method for systematic testing-monitoring of sulfide Co(Ni)Mo catalysts for hydrotreating is developed.
      
The hydrotreating activity of the catalysts was proportional to the amount of hydrogen consumed in the range 20-500°C during TPR.
      
Hydrotreating Ni heteropolytungstate catalysts have been prepared by impregnation of γ-Al2O3-alumina with solutions of H3PW12O40 acid and its Ni salt.

Course of construction and startup of the Chinese first large-scale combined hydrocracking unit together with the development over the 30 years were reviewed. Commercial tests and applications of hydro-upgrading of FCC LCO as well as hydrotreating of gas oils at mid-pressure in the hydrocracking unit of Daqing Petrochemical Works were also expounded.

回顾了我国第一套大型加氢裂化联合装置建成投产的过程以及30年来的发展.对在大庆石化总厂加氢裂化装置上进行的劣质油中压加氢改质和蜡油中压加氢处理的工业试验及其应用作了阐述.

At the beginning of the 21 st century, the oil product consumption will be increased continuously with the annual average increasing rate as high as 4.7% approximately, so that the corresponding technological strategies must be adopted, such as for taking the way of deep conversion; development of the clean fuel production technologies; development of the hydrotreating process; control of the pollution in refineries; and using the substitutive fuels, etc. In recent years, rapid development of the world...

At the beginning of the 21 st century, the oil product consumption will be increased continuously with the annual average increasing rate as high as 4.7% approximately, so that the corresponding technological strategies must be adopted, such as for taking the way of deep conversion; development of the clean fuel production technologies; development of the hydrotreating process; control of the pollution in refineries; and using the substitutive fuels, etc. In recent years, rapid development of the world petroleum refining industry has been impelled by the progress of the new technologies, such as clean fuels production, hydrocracking, hydrotreating/resid catalytic cracking, delayed coking/CFB, fuel cells, and synthetic fuels, etc. Discussion and some suggestions are put forward for further development of China's petroleum refining industry.

21世纪初 ,油品消费量继续增长 ,我国“十五”计划期间油品消费量年均增长率约为4.7% ,为此需采取继续走深度加工的道路、发展清洁燃料生产技术、发展加氢技术、治理炼油厂环境污染、发展替代燃料等相应的技术政策。近年来 ,清洁燃料生产技术、加氢裂化、加氢处理 /重油催化裂化、延迟焦化 /循环流化床锅炉、燃料电池和合成燃料生产技术等重点新技术创新发展很快 ,促进了炼油工业的发展 ,本文作了评述并提出了建议

Iranian atmospheric residuum was processed with normal scheme of hydrodesulfurization/RFCC,the recovery ratio of light oil was 73.61%,the total recovery ratio of LPG and light oil could reach to 83.60%,but because of higher investment and operation costs of the scheme,its profit investment ratio was not high.When Iranian atmospheric residuum was processed with scheme of Residual Oil Pretreating(ROP)/hydro treating/RFCC,although LPG and light oil was lower for 2.03% than the former scheme,because the process...

Iranian atmospheric residuum was processed with normal scheme of hydrodesulfurization/RFCC,the recovery ratio of light oil was 73.61%,the total recovery ratio of LPG and light oil could reach to 83.60%,but because of higher investment and operation costs of the scheme,its profit investment ratio was not high.When Iranian atmospheric residuum was processed with scheme of Residual Oil Pretreating(ROP)/hydro treating/RFCC,although LPG and light oil was lower for 2.03% than the former scheme,because the process of ROP greatly reduced the investment and operation costs of hydro treating,therefore the total investment cost was reduced for 610 millions Yuan(RMB),and the total operation cost was reduced for 66.21 millions yuan(RMB) per year,thus the profit investment ratio was higher for 9% and the investment payment time was shorter for 10 months than the former scheme.

采用通常的渣油加氢脱硫 重油催化裂化 (ARDS/RFCC)方案加工伊朗常渣 ,轻油收率为 73 6 1% ,LPG和轻油总收率达 83 6 0 % ,但由于ARDS投资和操作费用较高 ,使得该方案投资利润率并不高 ;采用渣油预处理 加氢处理 重油催化裂化 (ROP/RHT/RFCC)方案加工伊朗常渣 ,尽管LPG和轻油总收率比ARDS/RFCC方案低 2 0 3个百分点 ,但由于采用ROP工艺大大减少了RHT的投资和操作费用 ,使总投资降低 6 1亿元 ,总操作费降低 6 6 2 1万元 /a ,因而使得该方案投资利税率比ARDS/RFCC方案高 2 5 % ,投资利润率比ARDS/RFCC方案高 9% ,投资回收期比ARDS/RFCC方案短 10个月
