Abstract: PROBLEM TO BE SOLVED: To provide a method of equalizing heat distribution in a reactor tube housing a catalyst. SOLUTION: When a catalyst monolith is used, reaction heat can be dispersed as desired and consequently a heat gradient is lowered and efficiently and catalyst performance are improved. The method of equalizing the heat distribution on the catalyst of the tubular reactor is provided and this method comprises packing >=1 catalytic monolith into the respective tubes of the tubular reactor.
