Title: METHOD FOR SELECTIVE REMOVAL OF POLYCYCLIC AROMATIC HYDROCARBONS FROM OILS OBTAINED AS A RESULT OF PETROLEUM PROCESSING
Abstract:
The invention relates to a method for selective removal of polycyclic aromatic hydrocarbons from oils obtained as a result of petroleum processing, comprising two separate processes: filtration through a porous carbon-containing bed comprising and filtration through microfiltration membranes. The method is particularly useful for purifying oils selected from unconverted oils obtained in hydrocracking processes, products of further processing of these oils, engine oil and used engine oil.
