Abstract
The composition of motor fuels is the most important factor dictating the kind and quality of vehicle emission. Gasoline vapour pressure, as well as its benzene, aromatic, olefin, oxygen and sulphur content, are important factors impacting the quality of air that we are breathing in. Prohibition of using leaded additives has brought many motor gasoline manufacturers into an unfavourable position due to technological outdatedness. One of the ways of prolonging their survival is to stop the reduction of profit manifested through the use of leaded additives as octane improvers.
Through the introduction of MMT (Methylcyclopentadienyl Manganese Tricarbonyl)-a manganese-based additive, Croatian (INA’s) refineries would even increase their savings with respect to using only leaded additives for motor gasoline production. The plan for the project entitled “MMT – UMG Production” has been elaborated and implemented at the Sisak Oil Refinery. The application of MMT for addition into motor gasoline has been preceded by laboratory tests of the said additive’s impact on the gasoline components and blends accounting for the quality of commercial motor gasoline.
The blending of compounds was made according to the formula obtained on the LP model. Analytical results have confirmed the LP model accuracy. Calculation on the LP model has provided results justifying the construction of an MMT addition plant and its application in motor gasoline production at the Sisak Oil Refinery. The 6-month test operation, started on 18 October, 1999, was successfully completed on 18 April, 2000. The LP model addition effects were compared to those obtained during test operation.
