Abstract The dissociation behavior of methane hydrate was experimentally investigated in the presence of a laminar air flow in a channel of constant height. The dissociation rate ( J ) increases with increasing air velocity ( U a ) in the range of velocity values 0.5–0.7 m/s and decreases with increasing velocity. When simulating the combustion of methane hydrate, it is necessary to take into account the strong temperature irregularities on the surface of the powder layer. The area of maximum temperature and maximum rate of dissociation is located near the side walls of the tank.
