Gasification of Miscanthus x giganteus pellets in a fixed bed pilot-scale unit

Popis výsledku v původním jazyce

Gasification of Miscanthus x giganteus (Mxgig), is highly promising due to the high efficiency of the process and the many advantageous properties of this crop. Pilot-scale, fixed bed gasification studies were performed utilizing this fuel at three temperatures (750, 850, and 950oC) to determine the process effects of temperature on gas quality and tar yields. Simple thermodynamic equilibrium modeling was successfully applied to the pilot-scale gasification process. The Mxgig crop performed well, with best process stability reached at temperatures of 800oC or higher. Average calorific values of the product gases were highest at around 850oC at 5.2 MJ.m-3. Tar yields gradually increased with increasing temperature and dropped after 900oC. The presented thermodynamic equilibrium model conformed well with experimental results, deviating little in terms of O2, CO2, H2, and CH4 and no more than 8.1% in the case of CO. This indicates that simple modeling methods can be utilized to predict gas compositions for the pilot-scale.
