  “加氢处理”译为未确定词的双语例句
    The process of selective hydrogenation of C 4 fraction and the catalyst employed was studied. Industrial side-line evaluation test shows that alkyne contents in C 4 fractions can be reduced from the original 0.9%~1.3% to less than 1.5×10 -5 by catalytic selective hydrogenation with multi-metal catalysts. The loss in butadiene is less than 1.5%.

  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.

Hydrocracking is one of the most important processes in modern oil refining industry. Existing hy-drocracking capacity is 9. 85 Mt/a in China and will be further expanded in the future. In recent years,large scale hydrocrackers were designed and installed in China to meet defferent demands of target prod-ucts. New technologies, such as those for MHC, MPHC, MHUG and lube oil hydrotreating, and corre-sponding catalysts have been developed and commercialized by Fushun Research Institute of Petroleumand Petrochemicals...

加氢裂化技术因原料和产品方案灵活性大,产品质量好,尤其是能提供优质的石脑油、航煤、柴油、蒸汽裂解原料和润滑油基础料等,已成为现代炼油和石油化工工业必不可少的加工工艺。我国现有加氢裂化装置加工能力为9.86Mt/a,今后还将进一步发展。近十几年来,我国不仅自行设计、建造了一批大型加氢裂化装置,同时抚顺石油化工研究院还根据需要发展了缓和加氢裂化(MHC)、中压加氢裂化(MPHC)、中压加氢改质(MHUG)和润滑油加氢处理等新工艺,并开发生产出系列配套的加氢处理、加氢裂化催化剂,满足了我国石化工业发展的需要。
