Original Abstract

The biomass pyrolysis and gasification techniques are counted among basic technological procedures for their use as sources of energy. By thermal gasification, combustible components are formed as well as many other undesirable compounds mainly polycyclic aromatic hydrocarbons, sulphur compounds and chlorine compounds [1]. This waste product is called the tar. Therefore, the tar is a complex mixture of various organic compounds and it causes the problems during gas application in congeneration units. But it could also lead to potential health risks because many compounds have carcinogenic and toxic effects. Within the scope of this work the analysis of tar samples from different materials, which were acquired with using equipment specified in Tar protocol, was performed [2]. Special attention was paid to samples of sludge from sewage treatment plants. As an appropriate analytical method the gas chromatography combined with flame ionization detection (GC-FID) and timeof- flight mass spectrometry (GC/TOF-MS, GCxGC/TOF-MS) were chosen. The samples (tar solutions in acetone) were refined before the final analysis. In the case of BTEX and n-alkanes, only filtration and dilution were used. In the case of polycyclic aromatic hydrocarbons, samples were filtered and then cleaned-up by column chromatography using silica gel. Gas chromatography with flame ionization detector (GC-FID) was chosen as an appropriate analytical method for the determination of target compounds from selected groups of BTEX and n-alkanes. Target compounds from the group of polycyclic aromatic hydrocarbons and their alkylated derivatives were determined by gas chromatography with mass spectrometric detection (GC-MS). The most represented compounds in the samples were naphthalene, benzene, toluene and phenol (g.m-3). With increasing numbers of aromatic rings decreases the amount of these substances that were detected in the samples.
