摘要：

Nanoporous materials can significantly promote the formation process of gas hydrate by reducing the barrier of physical chemistry. In this work, the CO2/H2/H20 hydrates formation with tetra-n-butyl ammonium bromide (TBAB) and nano A1203 or carbon nano tube (CNT) were studied and compared in term of kinetic curves. It was found that both TBAB-A1203 and TBABCNT could promote the CO2/H2/H20 hydrate formation process. Furthermore, compared with TBAB-A1203, TBAB-CNT has the better promotion effect on the CO2/H2/H20 hydrate formation process. It is interesting that the CO2/H2/H20 hydrate formation process with TBAB-A1203 represents reformation phenomenon. It possibly forms sI CO2/H2/H20 hydrate firstly and finally forms semiclathrate CO2/H2/H20 hydrate. (C) 2019 The Authors. Published by Elsevier Ltd.
