Hydrogenation Ability of ZSM-5 Zeolite.
Journal of The Japan Petroleum Institute, 1992 プロトン交換したZSM-5 (HZSM-5) およびアルカリ土類金属含有ZSM-5型ゼオライト (M-HZSM-5, M:アルカリ土類金属) 上でエチレンおよびプロピレンの水素化を行った。重合, 異性化, クラッキング, 水素化等の反応が併発するため, 生成物は低分子量のものから高分子量のものまで生成した。HZSM-5上で生成する低分子量のものは主にパラフィンであった。低級オレフィンの収率は用いるゼオライトの種類に依存し, 次の順に増加した。HZSM-5≈Mg-HZSM ...

Nonlinear Active Site Dynamic Behavior Over In Situ Generated Working Zeolites
Chemie Ingenieur Technik, EarlyView.The methoxymethyl mechanism over α, β, and γ site ensembles and the dynamic site‐interconversion mechanism reduce the induction period of propylene formation. The methoxymethyl mechanism acts on site ensemble α generating surface methoxy species (SMS), which, through the dynamic site‐interconversion mechanism, lead to SMS on site ensembles β and γ that

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
