<P>PROBLEM TO BE SOLVED: To ensure a feedstock gas to be fed to a vapor-phase catalytic reaction vessel in such a condition that the moisture content of the feedstock gas come close to its target value. <P>SOLUTION: A method for feeding a feedstock gas G as a mixture of an oxygen-containing gas A and a gas G1 containing a liquid feedstock W including a fluid W1 containing components to be used for the reaction and feedstock water W2 to a vapor-phase catalytic reaction vessel 3, is provided, the method comprising: the step of measuring the moisture content of the oxygen-containing gas A in the feedstock gas G; and the adjustment step of comparing the thus measured moisture content with a preset reference moisture content, and adjusting the feedstock water W2's level based on the result to vary the proportion of the feedstock water W2 in the liquid feedstock W, thereby maintaining the total moisture content of the feedstock gas G at a given level. <P>COPYRIGHT: (C)2013,JPO&INPIT |
