【摘要】 以r-Al₂O₃为载体用浸渍法制备了铂铬重整催化剂。在微型反应器上,用正庚烷的重整反应考察了上述催化剂的活性,探讨了催化活性与催化剂各组份配比之间的关系,发现铂铬原子比为1∶1的芳构活性,在较高温度下,优于单铂催化剂,显示出良好的催化重整活性。更多还原

【Abstract】 The Platium-Chromium catalysts support on r-Al₂O₃ were prepared by impregnetion. The aromatization of n-Heptane on the catalysts was investigated with a pules microcatalytic reactor-gas chromatography device. The results showed that the catalyst with atom ratio Pt: Cr=1: 1 had a better aromatization activity than the Pt-catalyst at higher temperature.更多还原
