The paper deals with the methods of preparation of crude oil samples and chromatographic analysis of petroleum hydrocarbons (alkanes, monoaromatic compounds, policyclic aromatic compounds), as well as the results of the analysis (chromatograms of the samples and concentrates of hydrocarbons). The analysis have been carried out on Shimadzu GC 2010-plus and PEGASUS 4D GCxGC TOF-MS chromatographs. In the analysis of alkanes, monoaromatic and policyclic aromatic compounds the column temperature comprised 60−330 оС, 40−120 оС and 70−300 оС correspondingly. Silicagel of 100−200 mehs size was used as a sorbent. Developed methods may be applied for the analytical purposes in petrochemistry and corresponding scientific research surveys as well.

Novel strains of hydrocarbons degrading microorganisms were isolated from oil contaminated soil and bottom sediments and identified. Isolates oxidize components of crude oil in presence of oxygen and can be used as a part of commercial biological products for oil destruction.

Before And After

The aim of the present work was to evaluate the biodegradation of petroleum hydrocarbons in clay soil a 45-days experiment. The experiment was conducted using an aerobic fixed bed reactor, containing 300g of contaminated soil at room temperature with an air rate of 6 L/h. The growth medium was supplemented with 2.5% (w/w) (NH4)2SO4 and 0.035% (w/w) KH2PO4. Biodegradation of the crude oil in the contaminated clay soil was monitored by measuring CO2 production and removal of organic matter (OM), oil and grease (OandG), and total petroleum hydrocarbons (TPH), measured before and after the 45-days experiment, together with total heterotrophic and hydrocarbon-degrading bacterial count. The best removals of OM (50%), OandG (37%) and TPH (45%) were obtained in the bioreactors in which the highest CO2 production was achieved.
