Obtención de biocombustible a través de co-pirólisis rápida de biomasa de eucalipto y palma

En la búsqueda de alternativas energéticas sustentables y menos contaminantes, el uso de la biomasa lignocelulósica ha cobrado gran importancia, ya que no sólo es renovable, sino que se encuentra en grandes cantidades; el uso de eucalipto – palma en la obtención de biocombustibles se lleva a cabo a...
