It is shown that in the initial period of catalyst operation at 210 to 220/sup 0/C the rate of methanol formation is independent of the granule size. With an increase in temperature, the effect of internal diffusion retardation becomes stronger and the rate of methanol formation decreases with an increase in the granule size. For catalyst samples which have partially lost activity, the rate of methanol formation at low temperatures is higher on large tablets than on fine granules. At temperatures above 240/sup 0/C the relationship of the rates changes: the rate of methanol formation on large tablets is less than on fine ones. It is suggested that it is expedient to replace tablets with larger granules at certain points in the reaction zone of an adiabatic shaft reactor. 4 references, 4 figures.
