Application status and trends in hydrodesulfurization (HDS) and olefine hydrogenation catalysts are reviewed. 综述了国内外加氢转化催化剂的开发应用现状和发展趋势。
This complex uses high-sulfur residuum as raw material with processes of delayed coking, and hydrodesulfurization. 该联合装置采用高含硫渣油为原料，并由延迟焦化、加氢脱硫等工艺生产精制油品。
The mechanism of hydrodesulfurization of coal with coke-oven gas has beenexplained in the paper,too. 此外，对高硫煤与焦炉净煤气共热解脱硫的机理也给予了解释。
Fixed bed resid hydrodesulfurization technologies have been patented by chevron,Unocal, IFP, UOP and SIPM. 关于固定床式渣油加氢脱硫技术，目前世界上雪夫隆、联合油、IFP、UOP和壳牌等5家公司有专利技术。
