College of Education for Pure Sciences, University of Mosul discussed a master dissertation on the preparation of zeolite from clay mineral ore and its inoculation with ruthenium chloride and its use in the structural reform of naphtha by the postgraduate student, Mr. Diaa Mahmoud Fathi Al-Hadidi. The dissertation reviewed the chemical composition and mineral components of the clay mineral ore under study and its selection for the preparation of zeolite, and the inoculation of the prepared zeolite with ruthenium chloride. The dissertation demonstrated the possibility of performing the structural reform process of naphtha components by using both doped and ungrafted zeolites as catalysts for this process. The dissertation highlighted the chemical composition of the ore, and it was found that it contains a high percentage of silicon and a good percentage of aluminum, which are major components of clay minerals.
