Abstract

A series of experiments for measurement of non-catalytic water-gas shift reaction rate was carried out in supercritical water at 380°-440°C and 10-30 MPa using a flow-type apparatus. At 380°C, the reaction rate gradually decreased to a minimum at around the critical point, and then increased with increasing water density. However, at 400°C, the reaction rate order was zero with respect to water density. The rate constant for the water-gas shift reaction was compared with a global reaction model, which can reproduce the experimental data of CO conversion. Original is an abstract.
