  Abstract

The NiS4 supported on F23 catalysts were prepared by the impregnation method. No diffraction line of nickel sulfate was observed up to 30 wt %, indicating good dispersion of nickel sulfate on the surface of F23. The addition of nickel sulfate to F23 shifted the phase transition of F23 (from amorphous to hematite) to higher temperatures because of the interaction between nickel sulfate and F23. 20-NiS4/F23 containing 20 wt % of NiS4 and calcined at 500 oC exhibited a maximum catalytic activity for ethylene dimerization. The initial product of ethylene dimerization was found to be 1-butene and the initially produced 1-butene was also isomerized to 2-butene during the reaction. The catalytic activities were correlated with the acidity of catalysts measured by the ammonia chemisorption method.
