He(単原子分子径:0.26nm)
H2(分子径:0.289nm)
CO2(分子径:0.33nm)

トルエン(分子径:0.585nm)
[第一工程]
白金を担持したアルミナ(脱水素触媒層)3.6mlを、流通式の脱水素反応器内に設置した。メチルシクロヘキサン(分子径:0.56nm)及び水素ガスを、脱水素反応器内に供給し、脱水素触媒層に接触させ、メチルシクロヘキサンを脱水素化した。脱水素反応では、脱水素反応器内の気圧を0.19MPaに調整した。脱水素反応器では、脱水素反応器に付属の外部加熱装置を用いて、脱水素触媒層の中心部の温度を350℃に調整した。脱水素反応では、脱水素触媒に接触させるメチルシクロヘキサン(気体)の流量を0.18ml/分に調整した。脱水素反応では、脱水素触媒に接触させる水素ガスの流量を8.0ml/分に調整した。
上記の脱水素化反応の生成物を、脱水素反応器から気液分離器内へ供給した。気液分離器内の温度を15℃に調整することにより、脱水素化反応の生成物を、気体(水素ガス)と、液体(トルエン、及び脱水素化されずに残存したメチルシクロヘキサン)と、に分離した。液体中の水素分子の含有率を溶存水素計で測定した。液体の水素分子の含有率は5.9mg/Lであった。
