Summary:Use of diverse biomass feedstock in a process for the recovery of target C5 and C6 alditols and target glycols via staged hydrogenation and hydrogenolysis processes is disclosed. Particular alditols of interst include, but are not limited to, xylitol and sorbitol. Various embodiments of the present invention synergistically improve overall recovery of target alditols and/or glycols from a mixed C5/C6 sugar stream without needlessly driving total recovery of the individual target alditols and/or glycols. The result is a highly efficient, low complexity process having enhanced production flexibility, reduced waste and greater overall yield than conventional processes directed to alditol or glycol production. Se describe el uso de carga de alimentación de biomasa diversa en un proceso para la recuperación de alditoles C5 y C6 objetivo y glicoles objetivo a través de procesos por etapas de hidrogenación e hidrogenólisis; los alditoles particulares de interés incluyen, pero no se limitan a, xilitol y sorbitol; diversas modalidades de la presente invención mejoran sinérgicamente la recuperación general de alditoles y/o glicoles objetivo a partir de un flujo de azúcar C5/C6 mixto sin la necesidad de impulsar la recuperación total de los alditoles y/o glicoles objetivo individuales; el resultado es un proceso altamente eficaz de baja complejidad que tiene una flexibilidad de producción mejorada, residuos reducidos y un mayor rendimiento general que los procesos convencionales dirigidos a la producción de alditol o glicol.
