Promoters like activated carbon, tetrahydrofuran (THF) or surfactants, have emerged as a critical part in making methane hydrates toward realistic applications. They not only compliment the hydrate formation but also play a significant role on the hydrate stability, which, in turn, affects how methane can be released for further use. Although there are a number of reports dealing with different aspects of promoters on methane hydrate formation and dissociation, there is very limited information on their roles on the methane formation kinetics. This work attempted to put this issue into a new perspective by looking at how different promoters, namely activated carbon, THF, and sodium dodecyl sulfate (SDS), affect methane hydrate formation kinetics. The extent of each promoter on the kinetics will be discussed. Investigation on whether there is any synergistic effect among different promoters will also be reported. Results will be beneficial for further development on the use of methane hydrates.
