400℃までの温度に耐えうるオ-ブンに、3つの独立した反応器系が取り付けられた。これらの反応器は、5インチ(”)(12.7センチメートル(cm))長さのロッド形状の、0.25”(6.35mm)ODを有するパイレックス(登録商標)ガラス管からなっていた。この反応器管は、空であるか(対照のために用いられる)、または触媒密度および用いられた触媒の重量に応じて、重さ0.25グラム(g)〜0.5g、長さ30〜75mmの範囲の床を有する触媒が充填された。この触媒および触媒担体系は通常は、より大きいペレットから選択された。これらは、商業的に入手可能であり、かつ粉砕されて、スクリーンを用いて直径1〜2mmのサイズにされた。これらの反応器までの(および反応器からの)加熱された供給(および出口)ラインは通常は、ニッケルもしくはインコネル(Inconel)600からできており、その中での反応体および生成物の凝縮または劣化を避けるために、当分野において周知の温度に維持された。
