摘要：
In this paper, we present the kinetics of CO2 hydrate formation in presence of additives at different operating conditions that result in the formation of pure sI hydrate, pure sII hydrates and a mixture of sI and sII hydrates. Visual observations of different hydrates formed are presented with the associated CO2 uptake achieved under different experimental conditions. We observe a striking contrast in hydrate formation behavior observed for CH4 hydrate and CO2 hydrate in presence of tetrahydrofuran (THF) under similar diving force and operating conditions. Based on our experiments, it can be inferred that hydrate formation kinetics in presence of the THF is highly influenced by the type of guest gas. (C) 2016 The Authors. Published by Elsevier Ltd.
