20.500.12556/RUL-137603 Modeliranje procesa pirolize biomase s simulacijskim okoljem Coco Biomass pyrolysis modeling with Coco simulator Piroliza je zelo kompleksna termo-kemična razgradnja snovi, ki poteka pri temperaturah, višjih od 300 °C v inertni atmosferi. Uporabnost biomase kot ogljično nevtralnega energenta ali surovine za nadaljnjo predelavo se poveča, če biomaso s pirolizo pretvorimo v tri značilne produkte – bio oglje, bio pirolizno olje in bio plin. Uvodni del magistrskega dela obravnava kemijsko sestavo raznih biomas in tehnološke značilnosti pirolize. Izvedena je analiza vpliva parametrov pirolize kot so temperatura, kemijska sestava, hitrost segrevanja, zadrževalni čas, vrsta reaktorja in velikost delcev na tvorbo produktov. V prosto dostopnem programskem okolju COCO je izdelan model hitre pirolize lignocelulozne biomase. Simulacijski model je enostopenjski z eno stehiometrijsko enačbo, povzeto iz literature. Kakovost simulacijskega modela se je preverila s primerjavo računskih in eksperimentalnih rezultatov, podanih v strokovni literaturi. Temperaturno območje simulacije je bilo v lastnem modelu, izvedenem v okolju MS Excel, razširjeno na interval 400-550 °C. Pyrolysis is a very complex thermo-chemical decomposition of a substance that takes place at temperatures above 300 °C in an inert atmosphere. The usefulness of biomass as a carbon-neutral energy source or raw material for further processing is increased if biomass is converted by pyrolysis into three characteristic products bio-char, bio-oil and bio-gas. The introductory part of the master's thesis deals with the chemical composition of various biomass and technological characteristics of pyrolysis. An analysis of the influence of pyrolysis parameters, such as temperature, chemical composition, heating rate, residence time, reactor type and particle size on product formation was performed. A model of rapid pyrolysis of lignocellulosic biomass has been developed in the freely accessible COCO simulator. The simulation model is one-step with one stoichiometric equation taken from the literature. The quality of the simulation model was verified by comparing the computational and experimental results given in the professional literature. The temperature range of the simulation was extended to an interval of 400-550°C in our own model, performed in the MS Excel. piroliza biomasa lignocelulozna biomasa simulacijsko okolje COCO obnovljivi viri energije pyrolysis biomass lignocellulosic biomass simulation environment COCO renewable energy sources true false false [E.
