Ni2P/TiO2-Al2O3催化剂的放大制备及其深度加氢脱硫性能
Scale-up of Ni2P/TiO2-Al2O3 Catalyst Preparation and its Performance in Deep Hydrodesulfurization
摘要
Abstract
Reactors with different specifications were used to prepare TiO2-Al2O3 composite supports by a sol-gel method (sol-gel). The scale-up process was followed the criterion of identical stirring power per unit volume. Tube furnaces with different sizes were used to prepare Ni2P/TiO2-Al2O3 catalysts by a temperature-programmed reduction (TPR) method in accordance with the scale-up criterion of identical reducing gas flow rate. The hydrodesulfurization performance of the catalysts was examined using a continuous fixed-bed reactor to investigate the “scale-up effect” in gelation and TPR processes (two key processes in catalyst preparation). The results show that the physical properties of the supports prepared in large scale is close to that prepared in small scale. Hydrodesulfurization at 603K, 2.5MPa, WHSV 2 h−1 and hydrogen/oil volume ratio of 500 for 90 h shows that the catalysts prepared in large scale achieves a conversion rate of 99.4%. The sulfur content in the model oil was reduced to 6 ppm, which was the same as the lab-scale test results. These results show that the preparation processes of the support and the catalyst are reliable and repeatable, and the scale-up of the catalyst is possible.关键词
