摘要： The present invention relates to a method of production of lignin and hemicellulose from a plant lignocellulosic material comprising the steps of:
(a) contacting a plant lignocellulosic material with an extraction solution during more than 2 hours at a temperature between 95°C to 110°C, thereby obtaining a solid fraction and a liquid fraction,
(b) separating the solid fraction and the liquid fraction,
(c) concentrating the liquid fraction so as to obtain a concentrated liquid fraction,
(d) mixing equal parts by weight of water with the concentrated liquid fraction so as to obtain a suspension comprising solid particles in suspension in a liquid medium,,
(e) separating the particles and the medium of said suspension,
(f) recovering the particles of said suspension thereby obtaining a fraction comprising lignin called lignified fraction,
(g) recovering the medium of said suspension thereby obtaining a fraction comprising hemicellulose called hemicellulosic fraction.-

摘要： The invention relates to a process for the simultaneous extraction of lignin and silica from lignocellulosic plant material, characterized in that it comprises the steps of:
a) fractionating the lignocellulosic plant material in the presence of an acid solution, so as to obtain a solid fraction comprising cellulose, residual lignin and silica;
b) extracting simultaneously lignin and silica from the solid fraction obtained in step a) with a basic solution, at a pH between 10 and 13 and at a temperature between 70°C and 90°C, so as to obtain a liquid phase comprising lignin and silica, and a solid phase;
c) separating the liquid phase and of the solid phase obtained in step b),
d) coprecipitating a mixture of lignin and silica comprised in the liquid phase, at a pH between 5 and 6.-

摘要： The invention proposes a lignin-phenol-formaldehyde resin, which is obtained by polycondensation of formaldehyde, phenol and lignin in the presence of a basic or acidic catalyst, characterized in that the lignin is a lignin that is not chemically modified at the available functional groups. This lignin has a low molecular mass and it comprises available functional groups chosen from the group comprising aliphatic hydroxyls and phenolic hydroxyls. The degree of substitution by weight of phenol with the said lignin is between 50% and 60%. The weight proportion of the said lignin and of phenol in the resin is equal to the weight proportion of phenol in a lignin-free phenol-formaldehyde (PF) resin.

摘要： A process for producing bioethanol includes the steps of pretreatment (consisting in destructuring the lignocellulosic vegetable raw material by placing it in the presence of a mixture containing formic acid, acetic acid and water, then in separating cellulose), of enzymatic hydrolysis and of alcoholic fermentation, characterized in that it includes, prior to the enzymatic hydrolysis, a step of partial elimination of the lignins so as to obtain a residual overall level of lignins (T), expressed as percentage by weight, which is non-zero and which is included in a range determined by a lower limit, and an upper limit Bsup, respectively equal to 0.30% and 4%. In order to obtain conditions of acidification before the enzymatic hydrolysis step, the process includes a step for re-acidification of the mixture, which is carried out with an acid, or of a mixture of acids, of determined pKa, and preferably with weak organic.
