Abstract:

        The possibility of use of bioactivated carboneous sorbent (BACS, carbon sorbent based on vegetal resources bioactivated by native complex of oiloxidizing microorganisms) for the degradation of various petroleum products in contaminated soil was investigated, petroleum biodegradation degree reached to 40%~50% during first 10~14 days, and more than 90% after the period above 30~40 days, the residual hydrocarbon content in studied soilground decreased to 2%~3%, obvious decrease of the content of saturates and aromatics components but notable increase of tar components and asphaltenes in the residual oil. In both Ukraine and Russia, the testing of BACS on contaminated natural oilfields at oilrecovery and oilrefinery enterprises was conducted. As a result, the high efficiency of BACS for eliminating petroleum contamination of soil was satisfied.
