Water effect on the new catalyst of high temperature shift conversion during first reduction

The water–gas shift reaction plays a major ro le in ammonia and hydrogen plant design and operation. Good performance of the shift catalysts, and attainment of a close approach to equilibrium and, hence, minimization of the CO slip from the catalyst system is critical to the efficient and economic operation of the plant and ensures maximum hydrogen production from the hydrocarbon feedstock. Excessive drying out of catalyst during first reduction was studied to identify its influence on the catalyst during normal operation.
