20.500.12556/DKUM-11879 Možnost uporabe Jatropha (Jatropha curcas L.) rastlinskega olja v proizvodnji biodizla Possibility of use Jatropha (Jatropha curcas L.) vegetable oil in biodiesel production Globalni svet se je zavezal k zmanjševanju emisij, zato je uvajanje biogoriv, predvsem biodizla, ki ga dobivamo s procesom zaestrenja iz rastlinskih olj, zelo aktualno. Izmed številnih rastlin, primernih za proizvodnjo rastlinskega olja, je Jatropha curcas dokaj neznana rastlina, ki ima številne prednosti, raste hitro in povsod po svetu, je nezahtevna, primerna je za zaščito pred erozijo, vsebnost olja v semenih rastline je zelo visoka, ima tudi velik donos na hektar, hkrati pa lahko nudi tudi možnost zaposlitve milijonom ljudi, ki živijo pod pragom revščine, zato je še posebej zanimiva predvsem za države v razvoju. Kljub vsem lastnostim in možnostim, ki jih nudi Jatropha in jih že poznamo, pa je ta še zmeraj relativno neraziskana. Zato sem v laboratoriju raziskovala njeno olje kot potencialni alternativni vir za proizvodnjo biodizla. Prišla sem do ugotovitev, da je Jatrophino olje skupaj z degumiranim sojinim oljem sicer povsem primerno biogorivo, čeprav analize naših vzorcev niso dale pričakovanega rezultata, saj sta po raziskavi najbolj ustrezala le dva vzorca iz sintez, in sicer vzorec, kjer smo Jatropha olje mešali s sojinim degumiranim oljem v razmerju 1:1 ter vzorec Jatropha olja in sojinega degumiranega v razmerju 2:1 z 20% prebitkom katalizatorja natrijevega metilata. Vsebnosti metilnih estrov in ostalih merjenih parametrov v teh vzorcih biodizla so ustrezale standardu SIST EN 14214. The global world has decided to decrease the exhaust fumes, so they initiated bio- fuel, which is produced from plant's oil. Among numerious plants suitable for the production of the plant's oil Jatropha curcas is relatively unknown. It has many advantages, grows rapidely all over the world, it is very undemanding, it is used to prevent erosion. The substance of its oil is very high, it enables great yield on hectare, offers possibility of employment to millions of people who live at the edge of poverty. Therefore, is extremly interesting for developing countries. Because of insufficiency in researching of Jatropha curcas in country, I did laboratory work in Pinus factory to analyse its oil as potential alternative source in biodiesel production. I came to the conclusion that Jatropha oil and soya oil are both perfectly suitable for bio-fuel eventhough analyses of our samples did not give the expected results. This research gave only two samples from syntheses, namely the sample in which Jatropha oil was mixed with soya ungummy oil in proportion 1:1 and the sample of Jatropha oil with soya ungummy oil in proportion 2:1 with 20% excess of catalyzer sodium methylat. The contents of esters and other measured parameters in these samples of biodiesel corresponded to the standard SIST EN 14214. biodizel jatropha emisije zaestrenje biodiesel Jatropha emission estrification true true false Slovenski jezik Angleški jezik Diplomsko delo 2009-09-22 12:07:07 2009-10-16 13:51:25 2022-04-12 00:17:53 2022-04-18 03:31:39 2009 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:1RCKBZ4B VS_Logar_Sanja_2009.pdf VS_Logar_Sanja_2009.pdf 1 F101C885497CA248AB69D3843F1046CD 73f28d7a88b2d3a7f6c514e3d7aaddac5cf97159e86bc28685e82e0f9e327cf9 403a3acb-7c03-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e589d1d3-1938-41cb-b683-25e3c6c918a0 https://dk.um.si/Dokument.php?lang=slv&id=10862 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
