Abstract

En 中文
• For TBAF, hydrate promotion weakens at concentration higher than 0.586 mol.%, while induction time values continue to improve. • Optimal thermodynamic promotion of TBANO₃ is observed at 1.172 mol.%, but increased inhibition occurs at temperatures above 286.15 K. • The system exhibits coexistence of gas hydrates and semi-clathrates, indicating the potential for selective propane separation. • A subcooling of 4 K was insufficient for co-formation of both structure types, whereas 7 K enabled it.
