The mechanical strength of pellets of MoO3-CoO-Al2O3 catalyst was measured and the results obtained are as follows: (1) The mechanical strength of pellets depends on the MoO3 content, CoO content and the calcination temperature. (2) The MoO3 content shows little influence on the mechanical strength. (3) The CoO content up to 2% increases the strength, this being almost constant in further addition of Coo. (4) The calcination temperature has a large effect upon the mechanical strength. The pellets, whose calcination temperature is 450°Cor 600°C, have maximum strength, unless they contain MoO3 above 20%. The effect of the calcination temperature on the mechanical strength can be explained by the solid state reactions which occur between three oxides during calcination.
