The present invention is directed to a method for producing products, such as fuel pellets, from lignocellulosic biomass. Lignocellulosic biomass having a moisture content of less than about 30% by weight is introduced into a reactor. A vacuum of less than about 500 torr is applied to the reactor. Steam having a temperature of between about 180°C and about 235°C is injected into the reactor. The biomass is maintained in the reactor between about 1 and about 12 minutes. The treated biomass having a moisture content less than about 30% by weight is removed from the reactor. Treated biomass is formed into a pellet.La presente invención está dirigida a un método para la producción de productos, tales como pelotillas de combustible, a partir de biomasa lignocelulósica. Biomasa lignocelulósica que tiene un contenido de humedad de menos de aproximadamente 30% en peso se introduce en un reactor. Un vacío de menos de aproximadamente 66661.1 pa se aplica al reactor. Vapor que tiene una temperatura de entre aproximadamente 180°C y aproximadamente 235°C se inyecta en el reactor. La biomasa se mantiene en el reactor durante entre aproximadamente 1 y aproximadamente 12 minutos. Biomasa tratada que tiene un contenido de humedad menor que aproximadamente 30% en peso se retira del reactor. La biomasa tratada se forma en una pastilla.
