Enhancement of water–gas shift reaction efficiency: catalysts and the catalyst bed arrangement

The results of studies devoted to the search for catalysts of water–gas shift (WGS) reaction that are highly active in a wide temperature interval are generalized. New compositions based on traditional and alternative, as regards the chemical composition, catalysts of high- and low-temperature WGS reaction are considered in detail. The single-stage arrangement of WGS reaction ensuring small temperature gradients in the radial direction of the catalyst bed are discussed.
