SažetakU radu je izvršena eksergijska analiza organskog Rankinovog ciklusa za iskorištenje energije biomase sa radnim fluidima m-ksilen, MDM, toluen i mješavinom (toluen/MDM/m-ksilen) u procentualnom omjeru 33/33/33. Analizirani su učinci termodinamičkih osobina radnih fluida i mješavine na performanse ORC sa regeneratorom, te su termodinamičke osobine radnih fluida i mješavine optimizirani pomoću eksergijske efikasnosti ORC kao objektivne funkcije, primjenom genetskog algoritma. Optimalne vrijednosti performansi ORC ciklusa su komparirane i analizirane pod istim uslovima izvora toplote i definisanim graničnim uslovima. Eksergijska analiza ORC pokazuje da su za iskorištenje energije biomase pogodniji m-ksilen i toluen, jer u odnosu na MDM (OMTS) i mješavinu (toluen/-MDM/m-ksilen) imaju više vrijednosti eksergijske efikasnosti, a samim time i manje ukupne eksergijske gubitke.
