Abstract

Nickel sulfide catalysts obtained by homogeneous precipitation were prepared by varying the homogenization time and the sulfiding temperature. The surface area with respect to preparation conditions was studied by the BET method. Structure characterization studies by X-ray diffraction showed the formation of two main crystalline phases (NiS1.03 and NiS-millerite). Their appearance depends on preparation conditions. Formation of millerite or NiS1.03 occurs at the constant sulfiding temperature, when time of homogenization of precursors increases. (C) 1999 Elsevier Science B.V. All rights reserved.
