多孔ZSM-5沸石与γ-Al2O3复合材料的合成及制备加氢脱硫催化剂
Abstract:
本发明公开了多孔ZSM-5沸石与γ-Al2O3复合材料的合成及制备加氢脱硫催化剂，涉及复合材料技术领域以及加氢脱硫催化剂领域。该复合材料经450~600度，焙烧3~8 h。所得性质如下：多孔ZSM-5沸石含量为5~95 wt.%，γ-Al2O3含量为5~95wt.%，比表面积为400~600 m2·g-1，介孔孔容为0.40~0.85 cm3·g-1，微孔孔容为0.06~0.15 cm3·g-1。该复合材料具有多级孔道结构、良好的水热稳定性、较高的机械强度以及其与负载的金属物种之间具有较弱的相互作用，改变了金属物种的存在状态，有利于金属物种的还原与硫化，易于在复合材料上形成高活性的多层的硫化钼或者是硫化钨活性相，提高了金属硫化物催化剂的加氢脱硫性能。
Abstract(English):

The invention discloses synthesis of a porous ZSM-5 zeolite and gamma-Al2O3 composite material and preparation of a hydrodesulfurization catalyst and relates to the technical field of composite materials and the field of hydrodesulfurization catalysts. The composite material is roasted for 3-8 h at the temperature of 450-600 DEG C, and has the following properties that the content of porous ZSM-5 zeolite is 5-95 wt.%, the content of gamma-Al2O3 is 5-95 wt.%, the specific surface area is 400-600 m<2>.g1, the mesopore volume is 0.40-0.85 cm<3>.g1, and the micropore volume is 0.06-0.15 cm<3>. g1. The composite material has multiple stages of porous structures, good hydrothermal stability, high mechanical strength and weak interaction with loaded metal species, changes the existence state of the metal species and promotes reducing and vulcanizing of the metal species, multiple layers of high-activity molybdenum sulfide or tungsten sulfide active phases are easily formed on the composite material, and the hydrodesulfurization performance of the metal sulfide catalyst is improved.
