Abstract
The aim of this research was studying the hydro treatment of extracted used oil from clay by phase transfer catalyst. The used oil was pretreated with local clay and then treated with isopropanol, butanol and potassium hydroxide solution. The treated oil was distilled and fractionated to obtain 400–550°C fraction. The fraction was hydro-treated using commercial clay supported by an adsorbed phase-transfer catalyst. The effects of the reaction temperature, liquid hour space velocity and total hydrogen pressure on the oil fraction properties were investigated. The basic properties of oil such as colour and viscosity index improved. Thus, it can be suggested the addition of a polymeric sulfonate with a catalyst described occurs viahere, here is a novel mechanism. The results were compared with those obtained using catalyst without any additive.
