摘 要：Alternative solid biofuels like Miscanthus are experiencing a growing interest for energy related use. In particular Miscanthus pellets have a high potential to accomplish the requirements of small scale combustion units – a homogenous fuel with constant properties. The production of Miscanthus pellets is comparable to the production of wood pellets. Due to the similar technical requirements pellet plants used for the production of wood pellets can be modified for the production of high quality Miscanthus pellets. Nevertheless, several technical details and process parameters need to be modified to meet the required quality standards of the DIN EN 14961-6. In the present work, pelletization experiments have been carried out with a ring die press in pilot plant scale to investigate the influence of different process and material parameters. Varied parameters are the die speed, the gap between the rollers and the die, i.e. the pressure gap as well as the press channel length and geometry. The produced Miscanthus pellets were evaluated according to their physical- mechanical properties and according to the energy demand of the pelletization process.
