Abstract: It is an object of the present invention to downsize facility for removing or reducing concentration of hydrogen sulfide and oxygen in gas and reduce facility cost. Syngas g contains hydrogen sulfide and oxygen as target constituents of removal or reduction in concentration. Hydrogen sulfide content and oxygen content in the syngas g are measured in a preceding measurement part 13. Then, the syngas g is contacted with desulfurizing agent 14a including iron oxide. Selection is made whether to further execute deoxidization in a deoxidizing part 16 or omit or simplify the deoxidization according to results of measurements in the preceding measurement part 13.

Abstract: The present invention provides an apparatus and a method which can be used for producing an organic substance effectively from a synthesis gas obtained from a waste incinerator. The apparatus 1 for producing an organic substance from waste, comprises a synthesis gas generation furnace 11, a fermenter 13, and a nutrient feeder. The synthesis gas generation furnace 11 generates a synthesis gas by partial oxidation of waste. The fermenter 13 contains a microorganism which produces an organic substance from the synthesis gas. The nutrient feeder 12 feeds a solid or liquid nutrient to the fermenter 13 when an amount of the synthesis gas supplied to the fermenter 13 is insufficient.
