A method for producing combustible pellets, comprising the steps of: introducing a lignocellulosic biomass having a moisture content of less than about 30% by weight in a reactor; apply a vacuum to the reactor; inject into the reactor a vapor having a temperature between about 180 ° C and about 235 ° C; keep the biomass in the reactor between about 1 and about 12 minutes; extract the treated biomass from the reactor; and form the treated biomass in a pellet.Un método para producir pellets combustibles, que comprende las etapas de: introducir una biomasa lignocelulósica que tiene un contenido de humedad de menos de aproximadamente 30% en peso en un reactor; aplicar un vacío al reactor; inyectar en el reactor un vapor que tenga una temperatura de entre aproximadamente 180 ºC y aproximadamente 235 ºC; mantener la biomasa en el reactor entre aproximadamente 1 y aproximadamente 12 minutos; extraer la biomasa tratada del reactor; y conformar la biomasa tratada en un pellet.
