In this research, the semicompletion time (t(95%)) of gas uptake in the process of methane hydrate formation in the presence and absence of sodium dodecyl sulfate (SDS) and silver nanoparticles (SNPs) is investigated. The experiments were carried out in a 460cm(3) stirred batch reactor at temperatures of 273.65 and 275.65K and initial pressures of 5, 5.7, and 7MPa. The results showed that the addition of both additives at all tested conditions, noticeably, decreases the semicompletion time of methane uptake, compared to pure water. The semicompletion time of methane uptake in the presence of 500ppm SDS, 45M SNPs, and 500ppm SDS + 45M SNPs is 75.6, 546.3, and 129.9min, respectively, while that for pure water it is 8729.0min at 273.65K and 7MPa.
