Gasoline is important strategic product, Octane Number is the most specification for indicate gasoline grade quality, vehicles specified gasoline like (gasoline 92, 80) which produced by schedule blending higher octane number (gasoline 95) and lower octane number (Naphtha), increase octane number of gasolines: Petroleum process, Blending addition, Chemical additives.
In this work serval petroleum waste extracts got from AMOC`s refinery plan had been investigated for wasted higher octane number components, Two extracts (light condensate hydrocarbon “Skim oil” and extracted aromatic) evaluated by S.A.R.A analysis (Saturates, Aromatics, Resin, Asphaltene), viscosity, color, detailed hydrocarbon analyzer for (Paraffins, Olefins, Naphthene, Aromatics) P.O.N.A, Research Octane Number RON, Finally confirmed by performance Cooperative Fuel Research CRF motor test as ASTM D-2699 for gasolines specifications.
Results showed that two extracts could replace 5% of premium gasoline 95 during blend with heavy naphtha for gasoline 80 productions, this high value considered as maximization mass production, production reduction without environment damage also and cost saving of wastes treatments.
