Reverse water-gas shift reaction over Pt/MoO_x/TiO₂: reverse Mars–van Krevelen mechanism <i>via</i> redox of supported MoO_x

Spectrokinetic investigation of reverse water-gas-shift reaction intermediates over a Pt/CeO2 catalyst

Kinetics of the Homogeneous Reverse Water-gas Shift Reaction at High Temperature

The high-temperature rate of reaction of the homogeneous, reverse water-gas shift reaction, rWGSR, has been evaluated in quartz reactors with rapid feed pre-heating at low-pressure and high-pressure conditions. The form of the powerlaw rate expression was consistent with the Bradford mechanism. The Arrhenius expressions for the reaction rate constant corresponding to the empty reactor were in v...

Kinetic Study of the Reverse Water Gas Shift Reaction in High-temperature, High- Pressure Homogeneous Systems

Introduction The Water Gas Shift Reaction (WGSR), an important industrial reaction for the production of chemicals and/or hydrogen, is expected to play a key role in the integration of gasification technologies with a H2 production/recovery unit. The effluent stream of the gasifier, mainly H2, CO and CO2 at high pressure (up to 30 atm) and temperature (up to 1000C), will be directed to the wate...

Effect of MgAl2O4 catalyst support synthesis method on the catalytic activity of nickel Nano catalyst in reverse water gas shift reaction

In this research effect of synthesis method of magnesium aluminate as support of Ni catalysts at the reverse water gas shift (RWGS) reaction was evaluated. The RWGS reaction is applied in Carbon Dioxide Hydrogenation to Form Methanol via a Reverse Water-Gas Shift Reaction (CAMERE) process for the transformation of CO2 into methanol. The MgAl2O4 supports were prepared by sol-gel (M1), surfactant...

Water-gas Shift Reaction over Ceria-promoted Pt catalysts

Introduction The fuel processor in which hydrocarbon fuels can be converted into hydrogen has recently attracted much attention as a result of the advancement in the fuel cell technology. In a fuel processor, the water-gas shift (WGS) reaction plays a crucial role in the transformation of CO, a well-known poisonous gas to electrode of fuel cell, into hydrogen through reaction with steam. In WGS...
