Definitions
- the invention relates to a method for producing pulp paper, lignins, sugars and acetic acid from matter lignocellulosic plant constituting most of the plants annuals and perennials.
- the lignocellulosic materials of the invention are the whole plants or parts of these plants (stems, bark, %) or industrial co-products of food production (wheat straw, rice, barley) .; bagasse of sugar cane, bagasse of sorghum sugar .
- Pulp produced from plants perennials can be classified according to the technology used, their paper quality and the yield mass of obtaining relative to the initial plant material.
- the pulp quality of a paste is defined in relation to process of separating cellulosic fibers or defibration and compared to a series of physicochemical parameters the most important are the break length that translates the tensile strength, tear index and index burst. The higher these characteristics are, the better the quality of the dough produced.
- Processes for the production of quality paper pulp are essentially chemical in which the cellulosic fibers of the lignocellulosic plant material are cleared of cement plant, which binds them in plants, consisting of hemicelluloses (polymers of sugars with 5 or 6 carbons) and lignins (polymers of substituted allylic phenols) with a chemical action of hydrolysis in a basic aqueous or acidic medium concentrated, often in the presence of sulfur at different states oxidation.
- Formic acid B. BUCHOLZ and RK JORDAN Pulp and Paper, pp.102-104, 1983; MN. ERISMANN et al., Bioresource Technology, Vol. 47, p. 247 - 256, 1994
- MN. ERISMANN et al. Bioresource Technology, Vol. 47, p. 247 - 256, 1994
- This technology makes it possible to conserve silica contained in the plant in pulp, which is a important advantage when using annuals as raw material because the silica disrupts considerably, in the current industrial processes in the middle basic, recovery of mineral reagents.
- a variant of the process as under the name of process MILOX proceeds by cooking with formic acid in several stages in the presence of hydrogen peroxide which improves the delignification (K.POPPIUS - LEVLIN et al., Tappi Journal, Vol. 80, No. 9, p.215-221, 1997).
- Acetic acid can be used for the same purpose under pressure at higher temperatures (160 to 180 ° C) at concentrations in water of 50 to 90% (R. A. YOUNG and J.L. DAVIS, Holzforshung, Vol. 40, p. 99-108, 1986).
- the delignification is correct but the process requires a washing the paste with acetone to remove lignins precipitated on the dough.
- a variant of this process allows, with oxygen under pressure, reduce cooking times and improve the delignification (C. P. NETO and A. ROBERT, Holzforshung, Vol.46, p. 233-240, 1993), but it is at the origin of a partial depolymerization of cellulose by joint action pH and oxygen.
- bleaching technologies without chlorine of these pasta uses hydrogen peroxide in a basic medium, which leads to the adjustment of the silica in the form of silicate sodium causing significant problems when draining of pasta and recycling of reagents.
- the present invention aims to propose a new process for making pulp from plants annuals or perennials that lead to chemical pulps of good quality preserving in their structure the endogenous silica at atmospheric pressure.
- EP-A-0.584.675 it is taught a cellulose extraction process from lignocelluloces, by heating for 2 hours at high temperatures (170 ° C or 180 ° C) and under pressure in the presence of aqueous acetic acid and addition of formic acid.
- WO-A-95/21960 discloses a method of cooking of lignocellulosic materials, in particular of plants annuals) with a mixture of carboxylic acids, a compulsory step of pyrolysis.
- the invention is directed to a method which makes it possible to obtain these performance whatever the nature of the plants used and which is therefore particularly interesting in the case of annual plants to pave the way for new valuations, particularly in the case of cereal straw and bagasse of sugar cane, or sugar sorghum.
- the process according to the invention results from the observation surprising following: the addition of acetic acid to the acid formic can significantly increase the power solvating of the liquid organic phase thus defined vis-à-vis hemicelluloses and lignins without affecting the capacity acid hydrolysis of these biopolymers with formic acid. Of this way we avoid the degradation of cellulosic fibers which appears with concentrated formic acid alone in usual conditions of use, and therefore the paper quality of the pulp obtained.
- This property is particularly important since it is the main limiting factor in the use of chemical straw pasta, especially in fast paper whose speed they slow down.
- acetic acid preferably in molecular form, solubilizes lignins more easily thus released. This effect limits the reaction time and the possible formylations of the free hydroxyl groups of cellulose which degrade the paper qualities of the dough.
- the process allows a particularly valorization interesting annual plants, especially straws and bags, which are considered in the processes of manufacture of traditional chemical pasta as second-class products without much interest.

- the liquid / solid mass ratio will preferably be between 4 and 11.
- the separation of the pulp from the organic phase at the end of cooking is preferably carried out by pressing.
- Another preferred embodiment provides for the washing the dough thus separated by an acid mixture formic acid and acetic acid or pure acetic acid. Dough rid of most of the lignin and sugar residues is then washed with hot water.
- Another preferred embodiment proceeds by cooking in at least two stages to improve the delignification, and thus the quality of the pasta.
- the first step is carried out in the presence of the mixture formic acid / acetic acid.
- the second step is performed after having separated the pulp produced at the first stage into presence of anhydrous acetic acid.
- the washes of the dough are made with acetic acid.
- a preferred embodiment provides for the control pH during washing in organic acid medium so that the paper pulp at ideal pH for ozone bleaching in 1 or 2 sequences, to a dryness of the dough of the order of 40 to 60%.
- Another preferred embodiment provides for the separation of formic acid and acetic acid by evaporation under vacuum, the separation of the entrained water, the recycling of formic and acetic acids in the proportions required, and the recovery of acetic acid and water in excess.
