Abstract

Uz iscrpljivanje resursa neobnovljivih izvora i zabrinutost za zaštitu okoliša, povećao se interes za nove tehnologije stvaranja energenata. Od naftnih kriza početkom i kasnih 1970-ih uloženo je mnogo truda u razvoj procesa dobivanja tekućeg goriva iz biomase. Piroliza je jedna od najprihvatljivijih metoda takve pretvorbe. Tijekom pirolize, biomasa se brzo (1000 °C/s) zagrijava na oko 500 °C s vrlo kratkim vremenom zadržavanja pare (manje od 2 s), a pare zatim kondenziraju davajući tekućinu tamno smeđe boje koja se naziva biogorivo ili pirolizno gorivo. Zbog rastuće potrebe za vodom koja je uzrokovana povećanjem ljudskog stanovništva i industrije, veće su količine obrađene vode te time otpadnog mulja koji treba biti zbrinut. Taj mulj proizvedem obradom otpadnih voda se može pirolitički obraditi pri čemu se ujedinjuju energetske potrebe za gorivom te ljudske i industrijske potrebe za vodom.

Abstract (english)

With depletion of non-renewable resources and environmental concerns, interest in new energy generation technologies has increased. Since the oil crisis in the early and late 1970s, much effort has been put into developing the process of producing liquid fuel from biomass. Pyrolysis is one of the most accepted methods of such conversion. During pyrolysis, the biomass is rapidly (1000 °C/s) heated to about 500 °C with a very short vapor retention time (less than 2 s), and then the vapors condense to give a dark brown liquid called bio-oil or pyrolysis oil. Because of greater water demand caused by the growth of the human population and industry, there are larger quantities of treated water and thus the waste sludge to be disposed of. This sludge produced by wastewater treatment can be pyrolytically treated, combining energy needs for fuel and human and industrial water needs.
