Abstract (Croatian)

U ovome radu prikazana je tehnologija proizvodnje sintetskih goriva na bazi ugljena kao polazne sirovine, tzv. CTL (eng. Coal to Liquid, odnosno „ugljen u kapljevinu“) tehnologija. Poseban naglasak stavljen je na proces indirektnog ukapljivanja ugljena, stoga su detaljno opisana dva osnovna postupka : Fischer-Tropsch sinteza i sinteza metanola. Uz sintezu metanola prikazan je postupak pretvorbe metanola u sintezni benzin, tzv. MTG (eng. Methanol-to-gasoline, odnosno „metanol u benzin“) proces, kojeg je razvila tvrtka Mobil, 70-tih godina prošlog stoljeća. U prvom dijelu rada prikazan je proces proizvodnje sinteznog plina te njegova pretvorba u sintezna motorna goriva. U drugom dijelu rada prikazana je ekonomska analiza CTL proizvodnje, te usporedba troškova CTL proizvodnje sa troškovima proizvodnje kapljevitih pogonskih goriva iz nafte. Nadalje, prikazana je strategija razvoja CTL industrije u budućnosti i rizici koji prate njen razvoj.

Abstract

In this work a production technology of synthetic fuels from coal, i.e. CTL (Coal to Liquid) technology was presented. Especially an indirect liquefaction process was analysed, hence two main procedures are decribed: Fischer-Tropsch synthesis and Methanol synthesis. Alongside Methanol synthesis it was also decribed a transformation of methanol into gasoline, i.e. MTG (Methanol to Gasoline) process, which was developed in 70s by company Mobil. In first section a production of synthetic gas and its transformation into synthetic motor fuels was described. In second section an economic analysis of CTL production and comparing costs of CTL fuel production and production of synthetic fuels from crude oil in refineries was presented. Furthermore CTL developing strategy in future and its risks was presented.
