Power generation with a gas turbine using a gasified fuel of inferior quality is accomplished with high efficiency by a method which comprises bleeding part of highly compressed air emanating from an air compressor driven by a gas turbine and introducing the part of highly compressed air into an oxygen adsorbing tower containing an oxygen adsorbent thereby causing the oxygen from the highly compressed air to be adsorbed by the oxygen adsorbent and, at the same time, allowing the nitrogen gas from the highly compressed air to flow in a highly compressed state through the oxygen adsorbing tower, desorbing the adsorbed oxygen from the oxygen adsorbent under a vacuum, compressing the oxygen gas resulting from the desorption and gasifying a fuel of inferior quality with the compressed oxygen gas as an oxidizing agent, effecting combustion of the gasified fuel of inferior quality with the remainder of the compressed air produced by air compressor, mixing the gas arising from the combustion with the highly compressed nitrogen gas having flowed through the adsorbing tower, and introducing the resultant mixture into the gas turbine thereby driving the gas turbine and inducing power generation.

A gas mixture separating apparatus comprises an adsorption column packed with an adsorbent; a gas mixture column-end feeding device for feeding a gas mixture to one of two ends of the adsorption column; an unadsorbed-gas column-end discharge device for discharging unadsorbed gas from the other end of the adsorption column; a pressurizing device for pressurizing the gas mixture to be fed to the end of the adsorption column; and an adsorber depressurizing device connected to the end of the adsorption column on the gas mixture feed side. It comprises further a gas mixture side-injection device for feeding the gas mixture to the adsorbent in the adsorption column from the shell side thereof. Further, the gas mixture side-injection device is branched from the gas mixture column-end feeding device. Further, the apparatus comprises concentration sensors for detecting the concentration of the same sorts of components in gas flow as are adsorbed by the adsorbent in the adsorption column in the vicinity of the locations at which a plurality of gas mixture side injection devices are installed.
