Abstract	A novel energy recycle system of organic waste materials is proposed. In this system, waste materials are converted into gaseous fuel by gasification, and subsequently applied to power generation systems using fuel cells. There are several technological problems that should be solved in order to realize the present system. In particular, an increase in the production of H/sub 2/ and CO gas from gasification and the development of a high efficiency removal system of contaminants in the gas are key factors for attaining high quality energy conversion and maintenance of the fuel cell operation in the long term. In order to understand the behavior of the entrained-flow gasification of organic waste, two types of fuel-coal and polypropylene (PP), were gasified in a 250 mm across and 3.4 m high drop tube furnace (DTF). The study has generated the following conclusions. (1) PP was perfectly analyzed at a temperature of 673 K, where significant weight losses take place. (2) For coal gasification, H/sub 2/ concentration is about 15%, CO concentration is about 25-30%, and CH/sub 4/ concentration is less than 5%. For PP gasification, an H/sub 2/ concentration decreases with an increase in oxygen-carbon molar ratio, and CO concentration is about 30-35%, more than coal gasification. (3) Carbon conversion increased with an increase in oxygen/carbon (O/C) molar ratio for coal and PP, and carbon conversion is about 70% for coal. For PP gasification, carbon conversion is 75%. (4) The cool gas efficiency decreased with increasing O/C for coal and PP. Moreover, for PP gasification, cool gas efficiency is 50% more than cool gas efficiency of coal at 40%.
