Abstract:
Fuels, including gasoline, diesel, and kerosene (jet fuel), are the most valuable products from petroleum. To enhance the quantity of these fuels produced from a single barrel of crude, heavier streams are cracked, or broken down into smaller molecules. Fluid catalytic cracking (FCC) typically utilizes a solid acid zeolite catalyst, often promoted with rare earth metals in a fluidized bed. Large molecules are broken down to create additional material in the naphtha range in order to produce more gasoline, a valuable product. The “cracked naphtha” stream often contains larger amounts of sulfur than virgin naphtha, since much of the sulfur in crude is in the form of heavy polynuclear aromatic molecules present in the FCC feed stream. The aim of this work was to evaluate and investigate a new component for contemporary gasoline such as low octane component and its effect under exploration properties of the mixture.
INTRODUCTION
A modern refinery is a highly integrated industrial plant, the main task of which is to efficiently produce high yields of valuable products from a crude oil feed of variable composition. Employing different physical and chemical processes such as distillation, extraction, reforming, hydrogenation, cracking and blending the refinery converts crude oil to higher value products. The main products are liquid petroleum gas, gasoline, jet and diesel fuels, wax, lubricants, bitumen and petrochemicals. Energy and hydrogen for internal and external use are also produced in a refinery. Currently, refineries meet changing societal needs concerning product specifications and quality by upgrading existing technologies and continuously developing advanced technologies [1].
