LV12131B - Process for producing of furfural and acetic acid - Google Patents

Abstract

Invention applies to the industrial obtainment of furfural and acetic acid from raw materials containing pentosanes, for instance, deciduous wood-pulp. Raw material is reduced to pieces of the size of technologic chips, dampened with salt or salt mixture, which by dissociation forms cations with a charge of at least two. Then the solution is treated under overheated water steam flow at the increased pressure. Steam that comes from the reactor and contains furfural, is condensed, thus acquiring secondary steam, which is used for extracting and purification of furfural and acetic acid with the rectification method, as well as for other purposes. The raw material being left over after treatment with water steam is unloaded from the reactor with the decompression method, in case of necessity - dehydrated by pressing and/or drying and used as fuel for obtaining technological steam and/or other purposes.

Method of Invention for the Production of Acute Furfural and Acetic Acid 1 A process for the production of furfural and acetic acid from pentosan-containing feedstocks by treating them with water vapor at a pressure of at least two, dissociating cations, in the presence of solutions, then dispensing end products with known methods, by dissolving end products with known methods, characterized in that, in order to reduce catalyst consumption and to obtain concomitant acetic acid, a solution of salt or salt mixture with a degree of saturation of 20 to 90%, not exceeding 15% by weight of the dry starting material, is applied and the pentosan-containing feedstock is treated to over 200 to 250%. ° C in a water vapor stream at a pressure of 0.7 -1.4 MPa. 2. A method according to claim 1, wherein zinc and / or aluminum sulfate is used as a salt or a mixture of salts. 3. A method according to claim 1, characterized in that the pentosan-containing feedstock is partially dewatered by pressing and / or drying prior to wetting the catalyst. 4. A method according to claim 1, characterized in that the catalyst solution is sprayed through the dies on a mechanically stirred and transported, or freely falling in a closed space, or on the surface of the particles of the raw material transferred in the air or gas stream. 5. A method according to claim 1, characterized in that the pressure is increased gradually or periodically during the process. 6. A method according to claim 1, characterized in that the steam supply is coordinated with the dynamics of furfural formation at the set other process parameters. 7. A method according to claim 1, characterized in that the acetic acid is released from the reactor outlet by extraction with furfural and subsequently separated by rectification or by other known methods. A method according to claim 1, wherein the condensation of the furfurol-containing vapor results in a secondary vapor used for the separation and purification of furfural and acetic acid from the chemical impurities by rectification or other purposes. Method according to claims 1 and 8, characterized in that the furfural-containing vapor is pre-condensed from mechanical impurities by filtration and / or rinsing with furfural-containing condensed or other known methods. Method according to claim 1, characterized in that the residue of the raw material after treatment with the water vapor is discharged from the reactor by the decompression method, but the steam generated during the unloading is condensed in a closed water cycle with continuous or periodic discharge of the circulating fluid to the chemical. and / or biological treatment. Method according to claim 1, characterized in that the raw material residue after treatment with the water vapor is partially dewatered by pressing and / or drying and used as fuel for the production of technological steam and / or for other purposes.
