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. 本发明提供了不同生物质原料在通过分级氢化和氢解处理回收目标C5和C6糖醇和目标二醇的方法中的用途。特定的目标糖醇包括但不限于木糖醇和山梨糖醇。本发明的各种实施方案协同地改善从混合C5/C6糖料流中的目标糖醇和/或二醇的总体回收率，而无需不必要地提高单独的目标糖醇和/或二醇的总体回收率。结果得到种高效、低复杂性的方法，所述方法相比于常规的糖醇或二醇生产方法具有更高的生产灵活性、更少的浪费和更高的总体收率。
