Abstract

LCO having different aromatic contents, distillation ranges, and nitrogen contents were hydrodesulfurized by using sulfide catalysts supported on alumina and silica-alumina-zeolite as an effort to find a better way to hydrodesulfurize LCO to meet the future regulations on sulfur content of diesel fuel. Although total sulfur contents were almost same for each other, BLCO and CLCO had much higher nitrogen content. The reactivity order of HDS was ALCO ≫ CLCO > BLCO for all catalysts. Remained sulfur content in ALCO was around 14-25%. However, BLCO and CLCO resulted in the total sulfur content of 26-47% after reaction at 340°C. While the reaction at higher temperature of 360°C gave less sulfur contents, the lowest sulfur content was 953 ppm S by NiMo-A from CLCO. CoMo catalyst showed higher activity in the HDS of all LCO samples. In contrast, HDS of 4,6-DMDBT was higher over NiMo catalyst than CoMo catalyst. Catalytic function of zeolite components for the HDS of LCO was blocked by large content of aromatic species. LCO showed very limited activity for HDS when compared to that of SRGO. LCO having larger aromatic content showed much lower activity. Nitrogen content in LCO had relatively small effects on HDS. CoMo and alumina showed better performance than NiMo silica-alumina-zeolite for HDS.
