AB  - According to scientific community and professional specialists, urging necessity to increase capacity of sources of energy can be partially achieved by using biomass as a raw material. This approach is justified by both economic and ecological reasons. In this paper the results of chemical study of the biomass Miscanthus × giganteus Greef et Deu. cultivated in the Republic of Serbia in the experimental field of the Institute for Application of Nuclear Energy in Zemun were presented. Study of an amount of ashes, elemental analysis of the biomass, and calorific value of the biomass (both higher and lower), which are critical parameters when estimating the quality of a biofuel, points out the possibility of utilization of the miscantus biomass as a fuel. Samples of the plant material for this study were collected during two harvesting periods: in the fall, when the biological yield is the highest, and at the end of the winter, when a highest quality biomass with respect to the combustion is obtained do to a decrease in moisture content and remobilization of the macro- and micronutrients from the above-ground parts of the plants to the rhizomes. Values of the studied parameters indicate that biomass meets the 'green' energy requirements because the amounts of oxides of nitrogen and sulphur in the combustion products would not threaten current quality of the environment and the amount of carbon dioxide produced would be consumed in the process of photosynthesis. Results of the chemical analyses strongly suggest to a high potential of utilization of the miscantus biomass as a biofuel (renewable source of energy) to generate thermal energy.
AB  - Delimičan odgovor stručne i naučne javnosti na pitanje kako povećati kapacitete energetskih izvora je upotreba biomase kao sirovine, kako iz ekonomskih, tako i iz ekoloških razloga. U ovom radu su prikazani rezultati fizičko-hemijskih ispitivanja biomase miskantusa (Miscanthus × giganteus Greef et Deu.), gajenog na teritoriji Republike Srbije, oglednom polju Instituta za primenu nuklearne energije, Zemun. Ispitivanjem količine pepela, elementarnog sastava biomase i kalorične vrednosti biomase (donje i gornje), koji su presudni za procenu kvaliteta biogoriva, ukazano je na mogućnost eksploatacije biomase miskantusa kao biogoriva. Prikupljanje uzoraka biljnog materijala za ovo istraživanje izvršeno je u dva žetvena roka: u jesen - vreme maksimuma biološkog prinosa i krajem zime, kada se dobija kvalitetnija biomasa za sagorevanje usled smanjenja sadržaja vlage i remobilizacije makro- i mikrohraniva iz nadzemnih delova rizoma. Vrednosti ispitivanih parametara pokazuju da biomasa ispunjava zahteve 'zelene' energije, jer produkti sagorevanja biomase svojom količinom (oksidi N i S) ne bi ugrožavali postojeći kvalitet životne sredine, a količina nastalog ugljenik (IV) - oksida ne bi predstavljala ekološki problem, jer bi se dalje uključila u proces fotosinteze. Rezultati hemijskih analiza argumentovano ukazuju na veliki potencijal upotrebe biomase miskantusa kao biogoriva (obnovljivog izvora energije) u proizvodnji toplotne energije.

AB  - Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups sediments of pretertiary age and sediments of tertiary age. Bulk and specific organic geochemical parameters were determined for their methylene chloride-methanol extracts, aimed at controling the relationship between the age of the sediment and the maturity of its organic substance. In this sense a general direct proportionality was observed. However, a better linear dependence of the bulk parameters was observed in the case of younger, tertiary sediments. That is to say, with samples of pretertiary age the organic matter maturity was approaching a definite limiting value contributing to an inferior linear dependence of their bulk maturation parameters. Nevertheless, the dependence was found to be preserved with specific maturation parameters (e.g., CPI; Fit/n-C18), the changes of which are generally more intensive at higher maturity degrees.
AB  - U ovom radu ispitivani su uzorci površinskih sedimenata sa različitih lokaliteta Srbije i sadržajem od preko 0,5% organske supstance, koji su se prema starosti mogli svrstati u dve grupe: sedimentne stene pretercijarne i sedimentne stene tercijarne starosti. U njihovim metilen-hlorid metanolskim ekstraktima određeni su grupni i specifični organsko-geohemijski maturacioni parametri da bi se proučilo da li postoji veza između starosti sedimenata i maturisanosti njihove organske supstance. U tom smislu, utvrđeno je da postoji opšta direktna propordonalnost. Međutim, nađeno je da grupni maturacioni parametri pokazuju bolju linearnu zavisnost kod mlađih, tercijarnih sedimenata. Naime, kod uzoraka pretercijarne starosti maturisanost organske supstance u većoj meri se približavala određenoj graničnoj vrednosti što je doprinosilo smanjenju očekivane linearne zavisnosti njihovih grupnih maturacionih parametara. Ipak, ta zavisnost je sačuvana kod specifičnih maturacionih parametara (na primer: CPI; Fit/n-C18) koji se izrazitije menjaju na višim stepenima maturisanosti.
