Uncatalyzed and Wall-catalyzed Forward Water-gas Shift Reaction Kinetics
The kinetics of the high-temperature (1070-1134 K), low and high-pressure gasphase forward water-gas shift reaction were evaluated in an empty quartz reactor and a quartz reactor packed with quartz particles. The power law expression for the reaction rate was consistent with the Bradford mechanism and was invariant with respect to pressure. The experimental rate constant was lower than that pub...
متن کاملA theoretical study of metal-metal cooperativity in the homogeneous water gas shift reaction.
The possibility of metal-metal cooperativity in improving the yield of the homogeneous water gas shift reaction (WGSR) has been investigated through full quantum mechanical density functional theory calculations. The calculations indicate that bimetallic catalysts would be likely to be more highly active than mononuclear metal-based catalysts for the WGSR. The results have implications for the ...
متن کاملBioreactor Scale-up for Water-Gas Shift Reaction
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
متن کاملHigh Temperature Water Gas Shift Reaction over Nanocrystalline Copper Codoped-Modified Ferrites
Iron-containing spinels, also known as ferrospinels, are widely used catalysts for the water gas shift (WGS) reaction. The catalytic activity of spinels containing transition metal ions as dopants or modifiers is influenced by the acid base and redox properties of these ions as well as by their site occupancy amongst the octahedral and tetrahedral sites in the spinel structure. It has been esta...
متن کاملBiginelli Reaction Catalyzed by Copper Nanoparticles
We recently reported a novel synthesis of copper nanoparticles from copper sulphate utilizing the charge-compensatory effect of ionic liquid [bmim]BF(4) and ethylene glycol. The nanoparticles were characterized and found to be stable for one year. Here we hypothesize that the stabilized nanoparticles should be able to catalyze one-pot multicomponent organic reactions. We show that the nanoparti...
