Identifikacija PAHova u pepelu poljoprivredne biomase metodom GC/MS

Abstract

Biomass is considered as the source of energy with the highest perspective both in terms of reducing greenhouse gas emission and limited resources of fossil fuels. Therefore, in the last few years, constantly working on developing and improving of combustion technology has been of great significance, and that would enable the use of agricultural biomass beams of different sizes and shapes as a renewable fuel for energy production. In Serbia, biomass has huge potential, many types and forms of biomass are available and can be obtained from various sources. On the other hand, such diversity of biomass makes it very complex fuel for producing energy. In the Agricultural Corporation PKB, the technology of cigarette combustion has been applied for nearly a decade and it is used for greenhouse heating. Considering that the law will regulate the monitoring and control of the content of volatile and semi-volatile organic compounds, such as polycyclic aromatic hydrocarbons, emitted during combustion of biomass, it is necessary to develop a method for their identification. GC/MS method was used for separation and detection of PAHs in fly ash extracts of agricultural biomass. It was found that of the 16 priority PAHs, only the last three (indeno (1,2,3-c, d) pyrene, dibenzo (a, h) anthracene and benzo (g, h, i) perylene) were not detected in cyclone fly ash.
