Abstrakt
Antud lõputöö eesmärgiks oli uurida nii biodiisli tootmise võimalusi mikrovetikatest kui ka biodiisli tootmise olukorda hetkel. Lisaks valmis lõputöö käigus fotobioreaktor, millega on võimalik mõõta mikrovetikate kasvuks vajalikke parameetreid ning neid muuta.
Lõputöö esimeses osas uurib autor biodiisli tootmise olukorda hetkel. Välja on toodud erinevad ettevõtted, kes asjaga tegelevad või tegelesid.
Teises osas süvendutakse mikrovetikate olemusse ning leitakse, miks mikrovetikatest toodetav biodiisel on suure potentsiaaliga alternatiiv fossiilsetele kütustele.
Töö kolmandas pooles keskendutakse mikrovetikate kasvatamisele. Võimalus on kasvatada mikrovetikaid nii avatud tiikides kui suletud fotobioreaktorites. Töös käsitletakse mõlemaid. Lisaks uuritakse toitelahuste valmistamist.
Neljandas ning viiendas pooles uuritakse lühidalt mikrovetikatest õli eraldamise protsesse ning biodiisli valmistamise võimalusi õlist.
Töö viimases, kuuendas, pooles arvutatakse fotobioreaktorile iseloomuslikud parameetrid, mille tulemusena bioreaktor ka valmis. Lisaks on tehtud reaktoriga katsetusi ning neid on analüüsitud.
This thesis has been written in order to study and understand different methods of producing biodiesel from micro-algae. Growing demand of fossil fuels and rapidly growing air pollution show the necessity for alternative sources of energy. There are lots of alternatives, but only few of them could substitute the needing for fossil fuels. One alternative is biodiesel, which can be made from any kind of oil. The most promising source of oil is micro-algae. Micro-algae are unicellular microorganisms, who use carbon-dioxide, light and very little fertilizers to produce oil and oxygen through photosynthesis. They can double their mass in 24 hours or even less. Micro-algae can be grown for usage of oils, as well as for reducing carbon-dioxide level in the atmosphere. Also a photobioreactor, a specially designed growth environment, has been built during this thesis. Different calculations has proved the guality of the environent as an ideal place for microalgal growth.
