A continuous and modular process converts lignocellulosic materials for the production of ethanol principally and / or chemicals such as methanol, butanediol, propanediol, hydrocarbon fuel, etc. Renewable lignocellulosic biomass such as but not all inclusive hardwoods (gum, beech, oak, sweet gum, poplar, eucalyptus, etc.), soft woods (pines, firs, spruce, etc.), corn stovers, straws, grasses, recycled papers, waste products from pulp and paper mills, etc can be used as feedstock. The process is designed to be modular and the feed entry point can be selected to adapt to different biomass feedstock.

The separated carbohydrates are further subjected to washing, cleaning, neutralization, and / or mild hydrolysis and subsequently fermented to produce ethanol. Residual lignin and extractives remained with the cellulose are removed by chemical treatment steps to enhance the fermentations of cellulose. Pre-hydrolysate after neutralization to neutralize and remove toxic components such as acetic acid, furfural, phenolics, etc. containing (xylose, arabinose, galactose) and hexoses (glucose) can be either separately or together with the purified cellulosic fraction fermented to produce ethanol.
