To screen a preferable kinetics promoter, the effects of sodium dodecyl sulfate (SDS) and sodium dodecyl benzene sulfonate (SDBS) within tetrahydrofuran (THF) solution on recovering methane (CH4) from simulated coal-bed methane (CBM) were investigated at 279.15 K and 1.50-4.50 MPa. The results show the addition of surfactants can remarkably enhance the hydrate formation rate. However, gas uptake, CH4 split fraction and split factor in THF-SDS solution are superior to those in THF-SDBS solution. Therefore, THF-SDS solution is an appropriately integrated additive for recovering CH4 from coal-bed methane gas mixture.
