Definitions

  • the hydrolysis of biomass is increasingly becoming a focus of economic interest as fossil fuels become scarcer.
  • the aim is to unravel all carbohydrates that can be used in plant biomass in an economically technical process.
  • the totality of all carbohydrates of a plant is called green sugar for the sake of simplicity, since the targeted carbohydrates are not only cellulose, but also hemicelluloses, starch, sucrose, pectins and the like. is.
  • the hydrolysis can be carried out in principle by the biological / enzymatic and chemical routes.
  • the latter variant exploits the hydrolytic action of acids of different concentrations.
  • we distinguish between two approaches One uses diluted acids at elevated pressure (eg 5bar) and elevated temperature (eg 150 0 C).
  • Saccharification with highly concentrated acids had economic importance in Germany until the end of the 1950s and until the late 1980s in the former Soviet Union. Saccharified wood in the form of wood chips or sawdust. Other substrates were agricultural waste products, such as grain husks. All have in common a high degree of dryness. This was ensured, inter alia, that the hydrolysis apparatus was preceded by drying. The reason for this is the strong heat development that results from supplying the highly concentrated acid. This can lead to the charring of the biomass. Of the Green sugar can be obtained only with losses and by taking along degradation products such as furan derivatives, which in turn can interfere in the further process (eg in the fermentation of ethanol). A variety of patent solutions attest to the economic importance. To meet the warming process, various efforts have been made.
  • the degree of dryness will be of particular importance in the future in the technical process, since in a bio-based economy it will not only depend on the utilization of wood, but on the utilization of all vegetable biomass. This has economic significance, in particular, since many biomass, such as green waste or sea algae, are moist and must be taken into account with the water content as quickly as possible. Conversely, it is economically advantageous if an operator of a hydrolysis plant can utilize biomass regardless of the degree of drying.
  • This invention describes a procedure that allows the economical use of different degrees of drying biomass for acid hydrolysis with highly concentrated acids, primarily hydrochloric acid. Description of the invention
  • the invention is based on the idea that highly concentrated acids are water-attracting. Therefore, all vegetable biomasses are subjected to pretreatment with a 15-25% hydrochloric acid solution. In this concentration range, the hydrochloric acid has a sufficient dehydrating effect with a moderate heat development. This pretreatment has many different consequences and advantages.
  • the dehydration can be carried out in the existing hydrolysis reactors.
  • the removal of the water takes place during the workup of the Grünzuckerhydrolysate by evaporation of hydrochloric acid and water.
  • the energy required for downstream water removal corresponds to the energy that is generated when the biomass is dried, e.g. in drum dryers, is needed. Net results by eliminating the drying equipment, a reduction in investment costs for the installation of a hydrochloric acid hydrolysis system.
  • hydrochloric acid is already used for gentle prehydrolysis, with C5 sugars (eg xylose), proteins and salts being dissolved.
  • C5 sugars eg xylose
  • proteins and salts being dissolved.
  • sugar solutions containing almost no crystallization-inhibiting substances are obtained.
  • inexpensive plastics such as PVC-C, for the construction of hydrolysis reactors, which would otherwise not withstand exposure to heat and aggressive media such as highly concentrated acids.
  • step A 1 kg of miscanthus straw with a dry matter content of 75% is treated successively in an extraction apparatus with 2 kg of 20% (A), 1.5 kg of 32% (B) and 1 kg of 41% (C) hydrochloric acid.
  • step A all proteins, salts and part of the hemicelluloses are solubilized.
  • the proportion of water in the biomass contributes to the dilution of the hydrolysis acid.
  • the temperature in the reactor rises from 2O 0 C to 26 ° C.
  • step B all portions of the hemicellulose and a portion of the cellulose are solubilized. This gives 1.5 kg of 32% hydrochloric acid, in which 156 g of C5 sugar (especially xylose), 81 g of glucose and 14 g of acetic acid are dissolved (by deacetylation of lignin).
  • step C the remaining carbohydrates are split hydrolytically. One obtains lkg of 41% hydrochloric acid in which 255 g of glucose, 8 g of Cellotetrose, 7 g of cellodiose and 18 g of acetic acid are dissolved. 150 g of hydrochloric acid-free lignin remain in the reactor.

Abstract

L'invention concerne un procédé pour l'hydrolyse de biomasses végétales indépendamment du type et de la provenance à l'aide d'acides hautement concentrés, principalement d'acide chlorhydrique. Ce procédé est caractérisé en ce que l'hydrolyse proprement dite est précédée d'un traitement préliminaire de la biomasse par de l'acide chlorhydrique dans une plage de concentration de 15 à 25%, ce qui rend un séchage de la biomasse inutile.
