The invention discloses a moderate temperature pressure swing adsorption method for CO2, H2S and H2 mixed gas separation, and belongs to the technical field of clean energy. The method of the invention conducts raw material gas separation under a moderate temperature without cooling and can recover raw material gas sensible heat, raise integral system heat efficiency, reduce system heat exchange equipment and lower system costs. Moderate temperature operation of the invention can effectively enhance adsorbent kinetics characteristics of adsorption and desorption and increase gas processing capability of the PSA system; meanwhile, simultaneous removal of CO2 and H2S components in the raw material gas is realized to reduce system equipment and system complexity; when the raw material gas only contains CO2 or H2S, individual removal of the CO2 or H2S from the raw material gas can be realized.
