Coal gasification is a key technological process to convert coal into synthetic gas, which can easily be used for chemical synthesis and power generation. Since the technology enables to utilize unexploited and globally distributed coal feedstock, it has become more important. The technology has been gradually put into commercialization in Japan and around the world. Nippon Steel Engineering Co., Ltd integrated conventional coal gasification technology with pyrolysis technology and is developing an efficient two stage entrained flow gasifier (ECOPRO gasifier) composed of a pyrolyzer and a partial oxidizer. 20t/d pilot plant operational tests were successfully completed. Major outcome include achievement of the world's highest cold gas efficiency, which is equivalent to 85% at a commercial scale plant, confirmation of the process stability and applicability verification of low rank coal including brown coal. We report the results of the coal gasification technology development as well as future development towards realization of commercial plant.
