Research of Oil Sorption by Natural Clinoptylolite

Abstract

The sorption capacity of natural clinoptilolite of the Transcarpathian field in relation to the Boryslav field oil has been studied. It is shown that the sorption of oil occurs almost immediately after its contact with clinoptilolite. This forms the absorption front, which moves up the zeolite layer. Based on the analysis of the sorption process, it was concluded that lighter fractions of oil are sorbed faster and play the role of "solvent" for heavier fractions. It is shown that the sorption capacity of initial clinoptilolite is slightly higher than that of thermally activated. It was found that with increasing dispersion of clinoptilolite the mass of sorbed oil increases significantly, but the sorption capacity of different fractions, taking into account the height of the working layer differs slightly.
