The Effect of Compositions (PIONA) on the Octane Numbers of Environmental Gasolines of Reformate, Isomerate and Hydrocracked Naphtha Blends by Using GC

Abstract

This paper will discuss the effect of compositions (PIONA) on the octane numbers of environmental gasolines of reformate, isomerate, and hydrocracked naphtha blends by using gas chromatography analyses. Six blends have been studied to produce environmental gasolines according to the European standard specifications of Euro 3, 4, 5, and 6. Moreover, the observation and evaluation of blends depend on how to reduce the aromatic content which causes many harms to the environment and thus other components must be taken into study. In addition, all blends have shown that iso-paraffins are with composition of more than 36 vol.% and these contribute to the production of high quality environmental gasolines. The results represent that blends 1 and 2 have 39.051 vol.% and 37.503 vol.% of aromatics respectively which allow the samples to lie within the specifications of Euro 3. Furthermore, blends 3 and 4 have 37.717 vol.% and 33.947 vol.% of aromatics respectively which allow the samples to lie within the specifications of Euro 4. In addition, the environmental gasoline blends 5 and 6 have 31.450 vol.% and 28.746 vol.% respectively of aromatics which match within the specifications of Euro 5 and 6 that represent the present specifications until 2020. Finally, all these blends are ready to be used in our country instead of the regular gasoline with Euro 2 specifications.
