Preparation of Ruthenium chloride-grafted Zeolite from a Clay Mineral Ore and Studying Their Catalytic Properties

Abstract

This research work include studying one of the natural mineral ores available in Al-Hawy area (Mosul city – Northern Iraq) by chemical analysis and X-ray fluorescence (XRF) to identify its components of the elements as oxides, X-ray diffraction was carried out to determine the percentages of clay minerals (natural zeolites) and non-clay minerals in the natural ore. The natural zeolites were concentrated by removing carbonate, iron and separating the convertible silica into sodium silicate, the prepared zeolite was converted into (H-form) by treated with ammonium nitrite solution (1M) ,then grafted with ruthenium chloride (RuCl3.6H2O) .The properties and specifications of the prepared zeolite (grafted and non-grafted) were studied using techniques of (XRF) ,(XRD),(BET) , (SEM) and (differential& thermo gravimetric analysis(DTA)&(TGA) ) ,it was found that have a chemical and crystalline composition within the specifications of zeolites, as well as a good surface area , thermal stability and selective porous channels.
