本発明の触媒の担体は、全体にわたって有効量のビスマスおよびリンが本質的に均一に分散した主にγ−アルミナであるアルミナを含んでいる。
本発明の完成触媒を形成するためには、触媒活性量の白金および塩素と、場合によってはレニウムを、当業者に知られている含浸技術によって担体に沈積させる。完成触媒に基づいて0.1重量%〜1.0重量%の白金が有効であることが分かっており、その結果0.15重量%〜0.6重量%が好ましく、0.20重量%〜0.30重量%が特に好ましい。完成触媒に基づいて0.05重量%〜2.0重量%の塩素が有効であることが分かっており、その結果0.8重量%〜1.2重量%が好ましく、0.9重量%〜1.1重量%が特に好ましい。レニウムが存在する場合は、完成触媒に基づいて0.01重量%〜1.0重量%のレニウムが有効であることが分かっており、その結果0.1重量%〜0.5重量%が好ましく、0.2重量%〜0.45重量%が特に好ましい。
水素処理したナフサ原料の改質は、高温高圧で水素の存在下に、そのような原料を本発明の触媒と接触させることによって達成することができる。操作条件は、0.5時間−1〜6時間−1、好ましくは1時間−1〜3時間−1の空間速度、約0.1MPa〜約3.5MPa、好ましくは1MPa〜3MPaの圧力、約315℃〜約550℃、好ましくは480℃〜540℃の温度、約1mol/mol〜10mol/mol、好ましくは約1.5mol/mol〜8mol/mol、より好ましくは約2mol/mol〜6mol/molの水素再循環ガスと炭化水素原料の比である。
この実施例では、3つの従来の触媒担体の調製を記述しており、担体Fは実施例1の担体Dと同じ濃度、すなわち、0.06重量%のビスマスを含有するアルミナを含んでおり、担体Gは実施例1の全ての担体と同じ濃度、すなわち、0.3重量%のリンを含有するアルミナを含んでおり、担体Hは純粋なアルミナを含んでいる。
この実施例では、3つの従来の触媒の調製を記述する。
この実施例では、実施例2の従来の担体F、GおよびHにPtおよびReを含む触媒のサンプルの調製を記述する。
この実施例では、本発明のPtおよびReを含有する触媒(実施例6からの触媒I)の性能を、従来のPtおよびReを含有する触媒(実施例7からの触媒J、KおよびL)と比較する。
