摘要:
使用板式金属基体整体式阳极Al2O3催化剂载体γ-Al2O3/Fe-Cr-Ni合金/γ-Al2O3(MPAA),通过溶液浸渍法制备 一系列负载Ru的催化剂,研究催化剂在煤油水蒸气重整(SRK)反应中的性能。结果表明:与Ru浸渍负载后500 ℃空气中焙烧的多孔阳极Al2O3 载体的催化剂Ru/MPAA-C相比,120 ℃烘干的催化剂Ru/MPAA-D显示了更高的Ru分散度和更好的催化剂活性及耐久性; 高温N2预处理可以完全分解Ru/MPAA-D催化剂上的前驱体; H2预还原不是Ru/MPAA-D上煤油水蒸气重整反应的必要步骤; Ce的添加明显改善了煤油水蒸气重整反应中催化剂的抗积炭性能,从而提高了催化剂SRK耐久性。在高液时空速(40 mL/(g·h))下,添加1.25%Ce的Ru/1.25Ce/MPAA-D催化剂表现出了优于商业催化剂的耐久性,显示了其产业化的可能性。
Abstract:
Plate-type metal-monolithic alumina supported γ-Al2O3/Fe-Cr-Ni alloy/γ-Al2O3(MPAA)was used to prepare a series of Ru catalysts.The performance of these catalysts was investigated in the steam reforming of kerosene(SRK).The catalyst prepared by solution impregnation and dried at 120 ℃(Ru/MPAA-D)had a higher metal dispersion and more favorable activity and durability than that prepared by solution impregnation and high temperature(500 ℃)calcination in air(Ru/MPAA-C).The shrinking of ruthenium dispersion caused by the oxidation of ruthenium chloride species at high temperatures was the main reason.High temperature N2 treatment could decompose the reducible ruthenium species on the Ru/MPAA-D completely.It indicated that H2 pre-reduction was not an essential procedure for the SRK reactions over the catalyst.Ce addition was found to enhance significantly the catalyst tolerance to carbon deposition and to improve the SRK durability of Ru/MPAA-D.The Ru/1.25Ce/MPAA-D catalyst with 1.25% Ce additive exhibited better durability than commercial catalysts under high liquid hourly space velocity(LHSV,40 mL/(g·h)),and demonstrated its industrialization possibility.
