Abstract
The main aim of this work is to study the physical changes in the gasoline portion of the Sudanese petroleum upon treating with synthetic zeolite. Treating gasoline with zeolites usually performed in order to enhance the octane number of the oil. The octane number measures the degree of the gasoline resist to self-ignition prior to combustion. Gasoline with higher octane number has higher tendency to resist self-ignition. Gasoline containing branched and aromatic hydrocarbons resists self-ignition rather than gasoline containing straight chain hydrocarbons. 2,2,4 trimethyl pentane name disooctane (has octane number 100) and n-heptane (has octane number 0) are used to measure the octane number of the oil under the test. Zeolites are frame work of tetrahedral silicates (TO4), with a net negative charge balanced by a positive cation. Zeolite/Li indicating that the Li cation is used to neutralized the frame work. Zeolite/refinery refers to an industrial zeolite brought from Sudanese Petroleum Company. The gasoline portion used before treatment with any zeolites is considered to be a standard and is called a blank. Physical properties (distillation, density, S.G@15OC, Reid vapor pressure and the degree of corrosion) were carried out for the blank, the mixture of zeolite/Li with the gasoline and the mixture of zeolite/refinery with the gasoline. The density of the gasoline after treatment with zeolite/Li was found to be higher than the density of the blank. The Reid vapor pressure of the gasoline after treatment with zeolite/Li was found to be lower than the Reid vapor pressure of the blank. The distillate properties (the initial boiling point IBP and the final boiling point FBP) for the blank, gasoline after treatment with zeolite/Li and zeolite/refinery were not found to change considerably. The blank and the blank after treatment with zeolite/refinery were found to possess the same degree of corrosion (1b) which is the slightly corrosive whereas the blank after treatment with zeolite/Li has a (2c) degree which is moderate corrosive.
