Mohammed Hajji Ali* and Omar Mosa Ramadhan

ABSTRACT

A zeolite catalyst was prepared from mineral clay after using both X-ray diffraction analysis and X-ray fluorescence technology to verify the minerals and the proportion of elements constituting the crude clay. The ore contains a percentage of silica (48.13%), which is a good percentage to be used in the preparation of zeolite. It was also found that the raw clay contains a percentage of alumina estimated at (10.08%) and this amount will be added to the amount of alumina extracted from bauxit ore, which contains an estimated percentage of alumina (54.02). %). After preparing the zeolites, XRD technology was used to identify a diffraction patterns and compare them with the standard diffraction patterns of different type of zeolites. XRF was also used to verify the ratio of the elements composing the catalyst. After preparing the catalyst, it was used to qualitatively improve the properties of Kirkuk crude oil naphtha, as the catalytic reforming reaction of naphtha was applied after choosing the initial conditions of time, temperature and proportion of the catalyst, the optimum conditions were confirmed by conducting many experiments The prepared catalyst proved that it has the ability to improve the properties of naphtha, this was confirmed by several measurements, including Octane number and API degree calculation, infrared spectroscopy, nuclear magnetic resonance spectroscopy.
