| Summary: | Title screen To date, there are no reliable and simple calculation models that simulate the kinetics of dissociation at negative temperatures. One of the important problems is to reduce the cost of storage and transportation of natural gas hydrates. The paper presents experimental data on the effect of layer thickness and temperature on the dissociation kinetics, as well as the effect of the external air velocity. The model enables effective modeling of the dissociation kinetics both outside the self-preservation region and in the annealing temperature window. The experiments were carried out in the presence of non-stationary and non-isothermal dissociation. The thickness of the gas hydrate layer significantly affects the dissociation rate. The effect of thickness persists over a wide range of air velocities. The inhomogeneity of the temperature field inside the powder layer increases with increasing layer thickness, resulting in the appearance of two self-preservation sites on the dissociation curve.
