Journal of the Fuel Society of Japan, 1959 コークス炉の乾留時間の経過に伴う発生ガス成分の変化を実験室炉と工場炉について比較検討した。操業中のニューオットー炉より装炭後時間経過1時間毎に平均ガスを採取しヘンペル法で分析, また同じ装入炭を実験室炉を用い600～900℃の乾留温度でガスを発生させガス量とガス成分を測定した。これらの比較から適当な仮定の下に実験式を求める時は実験室試験の結果から工場炉におけるガス成分を推定しうると考えられる。

The Canadian Journal of Chemical Engineering, Volume 103, Issue 7, Page 3270-3283, July 2025.Abstract Propane dehydrogenation (PDH) has become a significant method for propylene production. However, the systematic effects of catalyst acidity on dehydrogenation performance remain unclear. In this study, Pt‐based dehydrogenation catalysts with different acidities were prepared using n‐nonane modification, and their dehydrogenation performance ...
