Abstract:
It is disclosed a process to produce a bio-product starting from a ligno-cellulosic feedstock, comprising a pre-hydrolysis step of the ligno-cellulosic feedstock in one or more pre-hydrolysis vessels to produce a liquid pre-hydrolyzate comprising water and water soluble hemicellulose, followed by a multi-step hydrolysis of the water soluble hemicellulose. The hydrolysis steps are conducted in separated vessel. The liquid pre-hydrolyzate is subjected to a partial hydrolysis step in a first hydrolysis vessel, to produce a first hydrolyzate. A portion of the first hydrolyzate, comprising remnant water soluble hemicellulose, is recirculated in at least one pre-hydrolysis vessel and subjected to a second hydrolysis step. Another portion of the first hydrolyzate comprising monomeric sugars is removed and converted to the bio-product, preferably after a refining hydrolysis step. The process also produces a hemicellulose-depleted feedstock which is preferably treated to produce a cellulosic pulp. The bio-product comprises any chemical from the groups of polyols, diols, alcohols, and carboxylic acids, or lactic acid or the group consisting of ethylene glycol, propylene glycol, or a mixture thereof.

Claim (Index 5):
The process of  claim 1 , wherein at least one liquid composition selected from the group consisting of the liquid pre-hydrolysate and the first hydrolysate is subjected to one or more separation steps obtaining at least a hemicellulose enriched fraction and a monomers enriched fraction, wherein the concentration of water soluble hemicellulose in the hemicellulose enriched fraction is greater than the concentration of water soluble hemicellulose in the liquid composition, and wherein the concentration of water soluble monomeric sugars in the monomers enriched fraction is greater than the concentration of water soluble monomeric sugars in the liquid composition.
