Przedstawiono wyniki badań usuwania oleju zawartego w karbonizacie pochodzącym z pirolizy opon samochodowych w procesie destylacji z parą wodną. Wykazano dużą skuteczność tego procesu. Przedstawiono wyniki ilości usuniętego oleju w zależności od parametrów procesu: temperatury i czasu przebywania.

Oils were removed from waste tires carbonizates by steam distillation in batch system at 450°C and for 20 min. The final content of the oil in the carbon black was below 0.02%.

Industrial oil was collected using hydrophobic silica powders. Silica nanopowder was modified with octadecyltriethoxysilane (OTS) using spray pyrolysis reactor continuously. Besides nanoparticles, mesoporous silica powder synthesized using Pluronic P104 was adopted as another oil adsorbents. Spherical macroporous or meso-macroporous silica particles were prepared by selfassembly for the removal of oil. The effects of the amount of powder on the oil adsorption were studied and compared with the results of various silica powders. The meso-macroporous silica particles were found to be the most efficient, indicating that both specific surface area and porosity played crucial role.

Evaluation of surfactant and biosurfactant mixture usefulness in oil removal from soil, based on physicochemical studies and flushing experiments

Surface activity and wetting properties of nonionic surfactant Rokanol NL6, biosurfactant JBR 425 and their mixtures were investigated. On the basis of these investigations, the ability of both surfactants to remove the synthetic base oil (PAO 6) from sand was evaluated. Surfactants solutions were applied in soil flushing in column and in batch experiments. Column tests with the solutions of Rokanol NL6 and JBR 425 gave very poor results (25% oil removal), while washing in batch tests was much more efficient and the oil removal reached even 95%. The mixtures of both surfactants gave better results than those obtained for single compounds.
