Реферат: A series of MoO3/Al2O3 catalysts with a molybdenum oxide loading from 2 till 10 wt.% was prepared by incipient wetness impregnation of the support with a solution of molybdenum citrate complex. The use of citric acid in the impregnation solution during the preparation of MoO3/Al2O3 catalysts favoured the formation of highly dispersed molybdenum species. The degree of aggregation of molybdenum species in catalysts depended both on the molybdenum oxide loading and on the activation conditions. Samples containing mainly tetrahedrally coordinated molybdenum species in the form of surface monomolybdates according to UV-DRS data were active in the propylene metathesis. The catalyst loaded 7 wt.% MoO3 was the most active in the propylene metathesis reaction. It exhibited propylene conversion of 30% and a metathesis product selectivity of 96% at a temperature of 200 °C.
