Method and system for the torrefaction of lignocellulosic material |
摘要 |
<p>Systems and methods for producing torrefied lignocellulosic material in a commercially suitable process. The system comprises
a dryer for drying lignocellulosic material adapted to remove at least of a portion of moisture contained within the lignocellulosic material;
a torrefaction reactor adapted to operate at a pressure between 1 and 50 bar and at a temperature between 100 and 1000°C, wherein the torrefaction reactor generates torrefied biomass from the lignocellulosic material and generates torrefaction gas;
a first recycle loop adapted to recycle torrefaction gas back to the torrefaction reactor;
a cooler adapted to cool torrefied biomass, wherein the cooler is adapted to operate in a substantially oxygen-free environment;
a second recycle loop adapted to recycle inert gas to the cooler and to provide inert gas to the torrefaction reactor; and
a supply line adapted to supply inert gas for addition to the cooler;
wherein the system is adapted to use the inert gas as at least a partial medium for transferring heat among the torrefaction reactor and the cooler.</p> |
