Abstract

Procedimiento para pretratar biomasa lignocelulósica mediante oxidación química a alta presión.#Este procedimiento combina en una sola etapa la acción del peróxido de hidrógeno alcalino con una alta presión. Con este procedimiento los sustratos son parcialmente delignificados, mejorando su accesibilidad al ataque enzimático para producir azúcares fermentables, consiguiéndose rendimientos de hidrólisis próximos al 100%.
