Abstract Nowadays world is suffer from the environmental pollution from several sources. One of the most serious pollution sources is that coming from the petroleum industry such as pollution of sea water by petroleum oil, air pollution, and soil pollution. Egyptian Petroleum companies facing some difficulties in disposal of the residual heavy crude oil (Heavy Naphtha) that found in the refinery stage, these residuals has a serious impact on the environment if it treated in a wrong way. This master aims to protection of the ecosystem from petroleum contamination resulting from the residual crude oil (Heavy Naphtha) in the refinery stage. This can be carried out by conversion of oil residue into its light components. Heavy Naphtha plays an important role in our lives. Most transportation vehicles are powered by refined products such as gasoline and fuel oil as the same as cause contamination resulting from the residual heavy naphtha in the refinery stage. The study solve the environmental problem of the presence of heavy naphtha by using catalyst such as mica in chemical catalytic cracking process which is one of the safest ways to overcome this problem producing light component which is economic source for fuel and prevent it’s negative impact on the environment by protection of the ecosystem from heavy naphtha contamination resulting from the residual heavy naphtha in the refinery stage. In additions, using the commercial mica has been used as support of catalyst which considerable lower cost and more available by comparison another catalyst. The fresh mica was oxidized using concentrated nitric acid. 80 Catalyst preparation from the produced mica materials as oxidized mica (NM) and sulfonated oxidized mica (MNSO3H). Physicochemical characterizations for the obtained mica materials and catalysts as BET, XRD, FTIR, TGA, SEM and TPD analysis. Propping efficiency of mica and catalyst (MNSO3H) towards cracking of heavy naphtha |
