Decreasing the anthropogenic impact on the environment during oil production and refining is one of the most complex and diversified problem, requiring considerable resources and continuous monitoring. The resulting considerable amounts of oil sludge are the most dangerous source of pollution in terms of the load on natural environment. Studying physico-chemical properties of hydrocarbon sludge is very important for selecting an efficient method for its recovery. This paper presents the results of studying properties of the various sludge formed during refining, representing a complex system of organics, containing a wide range of hydrocarbons, water and mechanical impurities (sand, clay, silt, etc.), the ratio of which varies widely. As a result of oil sludge heavy residue hydroconversion in the presence of catalyst (MoS2), high degree of conversion of fraction boiling above 520°C (wt.%) and high yield of distillate fractions were achieved. The obtained data are of considerable interest for further research in order to develop technologies of continuous processing of oil sludge of different origin with the use of hydroconversion.
