Abstract

This invention relates to a process for the preparation of hydrolysate of lignocellulosic materials. An admixture of an organic acid and mineral acid is used for the pretreatment of lignocellulosic materials to get fermentable sugars like pentose and hexose sugars from the fibres present in said materials upon hydrolysis at a higher rate of conversion and yield.
