Present work deals with natural and artificial methane hydrate dissociation. The heating of the powder produced due to the temperature difference between the external air and the powder. The dissociation rate was determined by gravimetric method. The range of the partial self-preservation for the natural hydrate is significantly longer than for the artificial one and moved to higher temperatures. The destruction of the natural sample is slower than the artificial one. The time-averaged dissociation rate for the artificial sample is equal to 1,25 %/s and for the natural hydrate corresponds to 0,59 %/s.
