Coal gasification is a key technology for converting coal into substitute natural gas (SNG), the common feedstock for synthesis of chemicals and electricity generation. Now, the development of coal gasification technologies is conducted for commercialization all over the world. Nippon Steel & Sumikin Engineering Co., Ltd. developed the innovative coal gasification technology using the highly efficient two-stage entrained flow gasifier (ECOPRO®). The development of this process is now under the pilot plant stage with 20t/d coal gasification capacity. As a result, it was found that this process had the stability of this process and applicability of verification of low-rank coals including high ash brown coal. This paper reports on the results from operating the pilot plant using high ash brown coal as feedstock.
