The synthesis of 19 carefully selected Pt/γ‐Al2O3−Cl formulations was followed by high‐throughput catalytic testing in order to unravel the effect of an active phase formulation change on n‐heptane reforming performances. Pt/γ‐Al2O3−Cl catalysts were prepared with different Pt (0.3–1 %wt) and Cl (0.1–1.4 %wt) contents and using two γ‐Al2O3 supports so that both sites concentrations and sites locations at the crystallite surface vary among the catalyst pool. Catalytic tests were conducted in mild conditions for a comparison of catalysts in kinetic regime. Results show that Pt and Cl concentrations control the competition between hydroisomerisation, hydrogenolysis and hydrocracking pathways. Aromatisation, on the contrary, is poorly affected by formulation changes. Non‐monotonous trends linking Pt/Cl ratio to isomerisation selectivity are found for both γ‐Al2O3 supports. This study provides new insights for the description of bi‐functional transformations in catalytic naphtha reforming.

19合成精心挑选的Pt /γ-Al系2 ö 3 -Cl制剂以解开上的有源相制剂变化的影响随后的高通量催化测试Ñ庚烷重整性能。的Pt /γ-Al系2种ö 3 -Cl催化剂具有不同的Pt（0.3-1％制备重量）和Cl（0.1-1.4％重量）的内容和使用两个的γ-Al 2 ö 3载体，使得位点浓度和微晶表面上的位点位置在催化剂池之间变化。在温和条件下进行了催化测试，以比较催化剂在动力学条件下的性能。结果表明，Pt和Cl的浓度控制着加氢异构化，氢解和加氢裂化途径之间的竞争。相反，芳香化几乎不受配方变化的影响。联的Pt / Cl的比例到异构化选择性非单调的趋势被发现两者的γ-Al 2个ö 3载体。这项研究为描述催化石脑油重整中的双功能转化提供了新的见解。
