The gas hydrate growth/dissociation was monitored by following the pressure (gas intake) – temperature variations in a classical isochoric process. The effect of stirring on the hydrate formation kinetics and yield was clearly evidenced in the case of solid and pure water systems, whereas it did not show any influence in hollow silica; and in fact, the yields remained identical in both stirring and non-stirring experiments. Approximately 3.6 m.mol of methane per gram of water was consumed as MH in the hollow silica matrix and the formation kinetics was extremely fast (~180 min). However, the methane gas conversion into MH in solid silica and pure water systems was ~ 10 times higher in a stirred reactor when compared with a non-stirred system. 6 Oil and Gas Science and Technology 70 ARTICULO Dhanunjana Chari, Vangala 55151 Prasad, Pinnelli S.R. 55152 Murthy, Sarabu Ramana 55153 189446 189446 0 0 0 0 257265 BAAB BAAB 2026-03-06 200061682 0 200061682 2026-03-06 00:19:38 2026-03-06 ARTICULO
