Có những phương pháp nào khác để sản xuất olefin từ nguồn nguyên liệu khác ngoài ankan không?

Cracking of small alkanes catalyzed by solid acids such as the zeolite HZSM-5 proceeds by two mechanisms: (1) The unimolecular (protolytic cracking) mechanism, ... ... alkanes at very low reaction temperatures. The results of IL catalyzed isomerization and cracking reactions of pure n-octane are presented. Influence of IL ... By contrast, the dehydrogenation, terminal, and central cracking of n-C4H10 are catalyzed exclusively by [GaH]2+ cations in Ga/H-MFI at turnover frequencies ... May 14, 2010 ... The apparent rate coefficient for alkane cracking was described as the product of the number of alkane molecules per unit mass of zeolite that ... Catalytic cracking of n-alkanes and n-alkylbenzenes over H-ZSM-5 zeolite. Author(s). Smith, Gordon Christopher. Thumbnail. DownloadFull printable version (10.32 ... Catalytic cracking proceeds through the formation of ionic species on catalyst surfaces, and produces shorter, but branched-chain (not straight-chain) alkanes. Dans cette thèse, nous avons étudié le craquage monomoléculaire d'alcanes légers (C3-C7) par des zéolithes de structure différentes par spectroscopie IR ... Cracking alkanes worksheet ... Subject: Chemistry ... Age range: 14-16 ... Resource type: Worksheet/Activity. Cracking is the process of converting alkanes into alkenes and shorter alkanes. We crack alkanes because the shorter chain alkanes are more valuable (they ... Cracking is the breakdown of large hydrocarbons into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking ...
