Abstract
Isomerization of (Cs&Ce) is a process that involves the transformation of on molecular structure into another (isomer). The LSR is characterized by a low octan number. Historically this fraction has been blended directly into gasoline witho additional processing. This will give loss in octane rating of gasoline pool, so ti conversion of (Cs&Ce) paraffins to the corresponding branched isomers which ha a higher antiknock quality than the linear paraffins is needed to produce high oct£ blending component. The main purpose of the study is to discuss the effect operating parameters such as (temperature, liquid hourly space velocity, hydroger hydrocarbon mole ratio and pressure) on the isomerization of (C5&C6) fraction production of high octane gasoline .The temperature range was between (14( 260°C), liquid hourly space velocity was between (O.Shr -1hr-1), hydroger hydrocarbon mole ratio was between (0.5-6) finally pressure rang was between (10Kg/cm2-40Kg/cm2).The experimental work was carried out in a twin re system located in the laboratory of (APC). The study involves, the different me applied for production of high octane gasoline, with environmental study showing the effect of gasoline emissions on air quality and how to control it. A summ typical commercial isomerization unit yields, product properties, capital cost, requirements, overall investment and operating cost is presented in the study. The economic issues including prices, production and consumpt gasoline, was also presented. Also study showing that the reactor temperatun main parameter affecting the isomerization reactions. By increasing temperal rate of reaction increases to give maximum iso ratio. At excessive temperatures the value of iso ratio decreased. On the other hand both LHSV. mole ratio can determine the residence time of feed over the catalyst, and this on the iso ratio and catalyst activity. Finally pressure has no big effei ratio or octane number.
