Abstract

Novi proces koji kombinira dvije konvencionalne tehnike kontroliranja - apsorpciju i adsorpciju te sustav biološkog tretmana za zračne emisije proučavan je radi smanjenja emisije nekih hlapljivihn organskih spojeva(VOC). Kod apsorpcije-adsorpcije eksperimentalni rezultati pokazuju povećanje općeg kapaciteta unosa VOC-a zbog prisustva čestica ugljena u apsorbentima no ipak dolazi o do nedostatka poboljšanja u koji je pripisan neučinkovitom „shuttle“ efektu koji je potaknut premalenim kapacitetom adsorpcije topivog VOC-a na aktivnom ugljenu.

Zagađenje zraka u zatvorenom prostoru je složen problem koji uključuje čestice (poput prašine i dima), biološke tvari (plijesan, spore), radon, azbest, i plinovite zagađivače poput CO, CO2, NOx, SOy, aldehid i VOC-e.Ozonacija adsorbenata NaX, NaY i MCM-41 toluenom te potencijal bioloških metoda je proučavan radi pročišćavanja zraka u zatvorenom okruženju.

Abstract (english)

A new process combining the two conventional control techniques absorption and adsorption and biological treatment system was studied to reduce the emission of some hydrophilic volatile organic compounds (VOCs). At abspsorbtion-adsorption experimental results clearly reveal the increase of the global uptake capacity of VOC due to the presence of carbon particles but also it comes to the lack of enhancement in presence of activated carbon which was attributed moreover to an inefficient shuttle effect caused by a too small adsorption capacity of the soluble VOCs on the activated carbon.

Indoor air contamination is a complex problem involving particles (such as dust and smoke), biological agents (molds, spores), radon, asbestos, and gaseous contaminants such as CO, CO2, NOx, SOx, aldehydes and VOCs in the absorbent. Ozonation of toluene over NaX, NaY and MCM-41 adsorbents and biological treatment were studied targeting for indoor air purification.
