As coal is the most abundant fossil fuel, coal should be used for not only power generation but also production of fuel and agriculture chemicals. Staged coal gasifier can increase production of methane by controlling the feed oxidizer ratio between stages. The 50 tons per day pilot plant of the gasifier tested at Chiba prefecture in Japan from 1990 to 1995 by NEDO (The New Energy and Industrial Tcchnology Development Organization). The main objective is production of Hydrogen. The new 150 tons per day pilot plant has started construction from 1998 by Electric Power Development Co., LTD. EAGLE (Coal Energy Application for Gas Liquid and Electricity) project aims to increase efficiency of staged gasifer and to achieve high performance clean up system.
