“…Formation of methane must be involved in it since the equilibrium of reaction (1) is approached from the side of methane and steam. It also seems that the rate of the initial decomposition is greater than those of the equilibrating reactions, especially of reaction (2).…”

Summary:Steam-reforming of n-heptane on rhodium catalysts was investigated under atRhodium supported on silica was found to sinter considerably on reduction in hydrogen flow,The activity per weight of a catalyst increased with the concentration of rhodium supported composition determined by the following two reactions: i) CH4+H2O=CO+3H2, and ii) CO+H2O=CO2+H2.The composition was found to deviate considerably from the equilibrium at earlier stages of the reaction, but to approach it with increasing conversion of n-heptane. It was suggested that the rate of these equilibrating reactions, especially of the reaction ii), was smaller than that of the initial decomposition of the feed hydrocarbon.

“…Так, равновесная степень деметилирования толуола с образованием бензола в присутствии водяного пара и катализаторов на основе никеля может достигать 73 % при 427 ºС [46]. Помимо этого, по механизму НТППР с водой взаимодействуют алифатические [47][48][49] и полиароматические углеводороды [48]. Таким образом, преимуществом облагораживания ТНС в СКВ по срав-нению с акватермолизом в субкритической воде является возможность достижения более существенной глубины превращений ТНС с вовлечением воды в химическое взаимодействие с углеводородами, а не только с соединениями, содержащими гетероатомы, по механизмам гидролиза.…”
