The study provided evidence that paramolybdate ions introduced into the alumina surface, during calcination form multilayer patches which cover about half of the alumina surface; and characterized a hydrogen species which adsorbs during reduction, can be removed by evacuation at reduction temperature (approx. 500/sup 0/C), readsorbs very slowly at reduction temperature, and may be involved in hydrodesulfurization under severe conditions but not in ethylene hydrogenation at room temperature.
