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 3):
The process of  claim 1 , further comprising subjecting at least a portion of the remnant water soluble hemicellulose in the at least one pre-hydrolysis vessel to a second hydrolysis step, while pre-hydrolyzing a further portion of the water insoluble hemicellulose.
