Abstract
Cilj ovog diplomskog rada je istražiti primjenu viših alkohola (pentan-1-ola, oktan-1-ola, nonan-1-ola i oleil alkohola) kao ekstraktivnih otapala s visokim vrelištem za izdvajanje etanola iz fermentirane podloge u integriranom bioreaktorskom sustavu. Ekstrakcija etanola je istraživana u svrhu dobivanja ekološki, energetski i financijski učinkovitijeg procesa od uobičajeno primijenjene višestupanjske destilacije. Istraženo je toksično djelovanje ekstraktanta na kulturu kvasca Saccharomyces cerevisiae i ponašanje dvokomponentnih (ekstraktant–voda) odnosno trokomponentnih smjesa (ekstraktant-voda-etanol) te učinkovitost razdvajanja organske faze od podloge. Izrađeni su binodalni trokomponentni dijagrami za sustave pentan-1-ol/voda/etanol, oktan-1-ol/voda/etanol, nonan-1-ol/voda/etanol i oleil alkohol/voda/etanol. Na temelju binodalnih dijagrama izvršen je proračun potrebnih količina otapala za trostupanjski ekstrakcijski sustav i predložen je sustav tehnološke linije za izdvajanje etanola iz fermentirane podloge.
Abstract (english)
The aim of this work was to investigate the application of higher alcohols characterized by high boiling points (i.e. pentan-1-ol, octan-1-ol, nonan-1-ol and oleyl alcohol) as extraction solvents for the ethanol extraction from broth, fermented in the integrated bioreactor system. The goal was the development of the ecologically, energetically and financially more efficient process than conventional multi-stage distillation. Applied extractants were tested for its toxicity on the Saccharomyces cerevisiae yeast culture. The behaviors of two-component systems (extractant-water) and three-component mixtures (extractant-water-ethanol) were investigated toward the efficiency of separation of organic phase (extract) and the water phase (rafinate). Binodal curves were constructed for systems: pentan-1-ol / water / ethanol, octan-1-ol / water / ethanol, nonan-1-ol / water / ethanol and oleyl alcohol / water / ethanol. Binodal diagrams were used for the calculations of required solvent amounts for the ethanol extraction in the three-stage extraction system. The plants for ethanol production based on extractions with higher alcohols were proposed.
