Abstract

Kroz ovaj rad obrađena je tehnologija uplinjavanja organskih tvari te je na konkretnom primjeru reaktora predložena ideja automatske regulacije. Uplinjavanje je proces kojemu su ulazni materijali organske tvari u čvrstom, tekućem ili plinovitom stanju, dok je produkt sintezni plin koji se najvećim dijelom sastoji od vodika, metana, ugljikovog monoksida te ugljikovog dioksida. Iako još nedovoljno prisutno u komercijalnoj upotrebi, uplinjavanje može biti ekološki prihvatljivo rješenje za zbrinjavanje, to jest smanjenje otpada, kao i smanjenje stakleničkih plinova kada se kao ulazni materijal koriste obnovljivi materijali poput drvne biomase i drugih poljoprivrednih sirovina i ostataka. Uzimajući u obzir da se posljednjih godina intenzivno traže alternativna goriva, ovakvi reaktori mogu biti od iznimne koristi i u te svrhe, imajući na umu da je izlazni produkt plin vodik koji se nerijetko navodi kao gorivo budućnosti. Kako ovakvi reaktori nisu dovoljno istraženi i zastupljeni, teško je u potpunosti automatizirati cijeli proces. No, u ovom radu je dan pregled dodatne opreme kojom taj proces postaje znatno elegantniji, kvalitetniji i efikasniji.

Abstract (english)

The technology of gasification of organic substances is addressed in this paper and a concrete example of a reactor is used to propose the idea of automatic regulation. Gasification is a process in which the input materials are organic substances in solid, liquid, or gaseous states, while the product is a synthetic gas (syngas) consisted mainly of hydrogen, carbon monoxide, and carbon dioxide. Although still not widely used commercially, gasification can be an environmentally acceptable solution for waste disposal, i.e., waste reduction, as well as a reduction of greenhouse gases when renewable materials such as wood biomass and other agricultural residues are being used as input materials. Considering the recent intensive search for alternative fuels, such reactors can be extremely beneficial for these purposes, given that the output product is hydrogen gas, often referred to as the fuel of the future. As these reactors are not yet sufficiently researched and widespread, fully automating the entire process is challenging. However, this paper provides an overview of additional equipment that makes the process significantly more elegant, high-quality and efficient.
