Dry syngas purification process is capable to realize co-production of power and valuable chemical at low emission of carbon dioxide. Sulfur removal with regenerable sorbent is key technology to configure the process. The sorbent is used in desulfurization cycle which repeatedly conduct removal and release of sulfur compounds. It is essential to adjust operation time for removal and release to operate the process continuously. Multicycle test of zinc ferrite sorbent was performed to investigate effect of gas supplying condition to the sulfur release characteristic. Both gas flow rate and oxygen concentration can control duration for the sulfur release trend. This finding can be used to provide potential procedure to adjust schedule of sulfur removal and release during the cyclic operation of the sulfur removal process.
