...-preservation effect. Original laboratory tests on the kinetics of phase transitions revealed considerable differences in thermal responses of hydrate-bearing sediments under different pressures and temperatures close to in situ permafrost conditions. According to the experimental results, stable pore gas...

... experiments. The Freundlich isotherm (R² = 0.983, n = 0.575, K_f = 0.04 mg/g) was the best fitting among different user models. In the kinetic study, the pseudo-second-order model (q_e = 1.297 mg/g, K₂ = 0.182 g/(mg min...
