摘要：

The effect of the reaction medium on non-promoted and potassium-promoted NiMo-sulfide catalysts for the water-gas shift (WGS) reaction has been investigated. Water vapor induces hydrolysis of the sulfide phase to oxysulfides which also exhibit catalytic activity. Nickel hydroxide, formed as a result of hydrolysis, manifests a high catalytic activity in the water-gas shift. (C) 1999 Elsevier Science B.V. All rights reserved.
