摘要：
Results are given for a study of the thermobaric conditions and kinetics of the methane hydrate formation in bulk solutions with 0.5 mass % soy lecithin obtained in distilled water and aqueous salt solutions (containing 1 and 3 mass % NaCl) at 273.2 K and driving force 4 MPa without stirring. The addition of soy lecithin was found not to lead to a shift in the water-hydrate-methane phase equilibrium diagram. The presence of NaCl was found to lead to a 50% decrease in the absorption of methane into the hydrate in comparison with the soy lecithin solutions without NaCl. This finding can be attributed to precipitation of the soy lecithin in the salt solutions.
