Water-gas shift reactions are equilibrium controlled at high temperatures and kinetically limited at lower temperatures; hence the process needs a catalyst for the reactions to be driven forward at lower temperatures. The water-gas shift processes usually involve two catalysts, one working at a high...
The reforming of hydrocarbon with water vapor and the water-gas-shift r eaction (WGSR) are the traditional and economic technologies for the production of hydrogen. Three classes of WGSR catalysts, e.g. Fe 2O 3-Cr 2O 3, CuO-Zn O-Al 2O 3 an d Co-MoO 3-Al 2O 3, have been ...
