A systematic study of methane hydrate formation and dissociation was carried out in the suspensions of silica (diameter 50, 150 and 200 mu m) and natural bentonite-clay (collected from similar to 40 mbsf) from Krishna-Godavari (KG) basin. All the experiments were carried out in a stirred reactor using 10 wt% of silica and natural sediment samples. Presence of silica or bentonite-clay did not show any noticeable shift in methane hydrate dissociation corroborating the literature, however, nucleation and growth of hydrates were quicker in the presence of silica or bentonite system compared to pure hydrate system. The silica grains have also shown considerable effect on release of methane during the dissociation. (c) 2012 Elsevier B.V. All rights reserved.
