Definitions

  • the object of the present invention is to provide a method for producing a C 2 -4 glycol and a polyol from the aqueous phase of sorbitol, in particular to produce sorbitol from cereals such as corn, and then cleavage of sorbitol to produce a glycol.
  • the present invention relates to a process for the production of a C2-4 diol and a polyol from the aqueous phase of sorbitol, which comprises sorbitol in an aqueous solution in the presence of sodium hydroxide and a nickel/ruthenium cracking catalyst.
  • Sorbitol is hydrogenated from sorbitol to give the corresponding alcohol.
  • the present invention can produce hydrogen by methanol cracking, and the production method thereof is as follows:
  • the methanol and the desalted water are mixed in a predetermined ratio, superheated by pressurization, preheating, vaporization to a reaction temperature of 220-280 ° C, and the reaction pressure is about 0.9 Mpa, and in the presence of a catalyst, a conversion reaction is carried out to obtain a reformed gas.
  • the hydrogen content is 73-74.5%.
  • the high-temperature reformed gas is cooled and condensed to below 40 ,, and refined by a conventional method to obtain 99.5% of hydrogen hydrogen to be used.

Abstract

L'invention concerne un procédé de fabrication d'alcool dihydroxy C2-4 et de polyol par craquage de sorbitol dans une phase aqueuse, en particulier un procédé de fabrication d'alcool dihydroxy C2-4 et de polyol en utilisant du blé comme matière première pour obtenir du sorbitol, avant hydrocraquage du sorbitol. Le processus englobe l'hydrocraquage du sorbitol pour obtenir un mélange d'alcool dihydroxy C2-4 et de polyol en présence d'hydroxyde de sodium et de catalyseur de craquage Ni/Ru à haute température et à une pression élevée, et l'élaboration des produits individuels par séparation et raffinage. Le processus de l'invention a de nombreux avantages: le déroulement de la production est novateur, les conditions de traitement sont uniques, plusieurs types d'alcool peuvent être obtenus simultanément et la qualité des produits est meilleure que celle obtenue avec les autres processus. Un autre avantage majeur de l'invention réside dans le fait que le processus peut utiliser du grain comme le blé en tant que matière première, c'est-à-dire une ressource renouvelable au lieu d'une ressource non renouvelable.
