Abstract
The present invention relates to a sequentially fed process for enzymatic hydrolysis in which, under agitation, a pre-treated lignocellulosic substrate is brought into contact with water and with enzymes in a reactor, said process being characterised in that the sequential addition to the reactor of the pre-treated lignocellulosic substrate is carried out increasingly spread out over time, in order to obtain a predetermined final content of dry matter.
Claims17
A process for enzymatic hydrolysis of pre-treated lignocellulosic substrate, comprising bringing into contact, under agitation, at least one pre-treated lignocellulosic substrate, which comes from raw or treated wood, marine biomass or a by-product of agriculture, with water and with enzymes in a reactor, comprising adding the at least one pre-treated lignocellulosic substrate to the reactor in a sequential batch-wise manner such that intervals between additions of batches are longer over time within the same process, and obtaining a predetermined final content of dry matter that is higher than 12% by weight.
A process for enzymatic hydrolysis of pre-treated lignocellulosic substrate, comprising bringing into contact, under agitation, at least one pre-treated lignocellulosic substrate with water and with enzymes in a reactor, comprising adding the at least one pre-treated lignocellulosic substrate to the reactor in a sequential batch-wise manner such that intervals between additions of batches are longer over time within the same process, and obtaining a predetermined final content of dry matter that is higher than 12% by weight, wherein the at least one pre-treated lignocellulosic substrate comes from raw or treated wood, or a by-product of agriculture.
A process for enzymatic hydrolysis of pre-treated lignocellulosic substrate, comprising bringing into contact, under agitation, at least one pre-treated lignocellulosic substrate, which is not from paper industry, with water and with enzymes in a reactor, comprising adding the at least one pre-treated lignocellulosic substrate to the reactor in a sequential batch-wise manner such that intervals between additions of batches are longer over time within the same process, and obtaining a predetermined final content of dry matter that is higher than 12% by weight.
