The Effect of PIONA Compositions on Octane Number

PIONA (Paraffins Isomerate Olefins Naphthenes and Aromatics) analysis is a method to analyze petroleum naphtha and gasoline to determine their compositions and ratios. PIONA analysis has been observed to be the key to select the high quality samples of gasoline the deep in refining processes contribute to produce more useful refinery products (Reformate Isomerate and Hydrocracked Naphtha) that aid in upgrading the gasoline samples by blending the obtained refinery products along with gasoline to enhance their octane numbers. The European Standard Specifications contribute to the selection of environmental gasoline to reduce the exhaust that causes air pollution.
