Abstract
Auto Oil Programme presented in the middle of 1996 by the European Union Commission determined the allowed emissions from motor vehcles and consequently influenced the future quality of motor fuels. On the basis of comprehensive tests performed within the Programme, there have been defined critical parameters of fuel quality included in the EU Specifications to be applied since 2000 and 2005. The novelty of these Specifications lies in the fact that they determine also the structural group composition of fuels with extremely strict requirements regarding the sulphur content restrictions (limitations).
Due to these limitations, achievement of the main applicational properties of fuels (octane number or cetane number) will require from refineries a careful formulation of fuels, i.e. optimization of composition for the purpose of meeting the strictly prescribed limits of emissions from engines. Limitation of the sulphur content in motor fuels represents an additional factor essentially determining the fuel quality and directing the technological development of refineries. Optimization of motor fuel blending therefore represents an extremely important factor in the fuel production, particularly in case of restricted resources taking into consideration the availability of individual blending components. The objective of optimization is in achieving the quality parameters with an acceptable cost-effectiveness.
This work has dealt with the example of optimal formulation of unleaded motor gasoline. Mathematical model of blending has been formed by the method of linear programming with limitations prescribed by the "Auto Oil Programme".
