Abstract

This research was conducted for photodegradation of gas oil using nano clays (bentonite) by 30% of TiO2 loaded on the clay , for the purpose of fragmentation chains hydrocarbon long polluting the environment and converted to short chains and gas, and carried out operations cracking through the design of a photocell according to the specifications laboratory, using xenon lamp wave length (200-800 nm) and by passing the air for a specific time periods (4,6,10) hours, after which the components of the models were measured by a gas chromatography (GC), as well as the use of a radiation infrared (FT-IR) to identify groups effective of gas oil before and after degradation , The results obtained from the analysis (GC) that there is a change in the percentage of some compounds hydrocarbon paraffin such as(Nonan, Dodecane, Hexadecane) that is to know the time of Retention solutions( standard compounds), as was observed decrease ratio compound Hexadecane and increasing the percentage Alnonan gradually in the gas oil over time of irradiation and this shows the transformation of long chains in gas oil into shorter chains ,As for analysis by (FT-IR) the appearance of the carbonyl group (C=O) which indicates the occurrence of oxidation process of some organic compounds during degradation .
