摘要: 新型多孔粘结剂通过酸处理高岭土制得,具有丰富的中/大孔、良好的水热稳定性和抗重金属性能。采用其制备的催化剂具有低磨损指数和大孔容。固定流化床评价表明,与基准催化剂相比,转化率增加了3.50%,重油收率降低2.86%,总液体收率和轻油收率分别增加2.82%和0.79%。新型多孔粘结剂优异的孔结构、良好的水热稳定性和抗重金属性能决定着良好的反应性能。

Abstract: A novel porous binder was obtained from acid-treated kaolin. This new binder possessed abundant meso/macropores, good hydrothermal stability and heavy metal resistance. The prepared catalyst using new binder featured low attrition index and large pore volume. The catalysts were tested in a fixed-fluidized bed reactor unit. In comparison with the reference sample, the oil conversion achieved by the CAT-new-1 catalyst increased by 3.50%, and heavy oil yield decreased by 2.86%, while the total liquid yield and light oil yield increased by 2.82% and 0.79%, respectively. The perfect pore structure, good hydrothermal stability and heavy metal resistant performance of new binder were the possible causes leading to its outstanding performance.
