    Continuous and stable operation of a membrane reactor for 1054 h to dehydrogenate methylcyclohexane for the purpose of producing high-purity H<inf>2</inf>, using a dimethoxydiphenylsilane (DMDPS)-derived silica membrane, is successfully demonstrated. The silica membrane used was prepared via a chemical vapor deposition method, using DMDPS as a precursor, and Pt/Al<inf>2</inf>O<inf>3</inf> catalysts were employed and loaded inside the tubular membrane. During the 1054 h of continuous operation, an equilibrium shift was stably demonstrated, because of the stable extraction of the produced H<inf>2</inf> from the reaction side to the permeate side, and, accordingly, the purity of H<inf>2</inf> in the permeate gas was stably high. Although the DMDPS-derived membrane showed a slight decrease in performance after 1054 h of operation, followed by regeneration under an H<inf>2</inf> atmosphere, this first successful demonstration of the long-term stable operation of a membrane reactor using silica membranes is of significance to its practical and industrial use.
