Abstract

The study encompasses an investigation of a local natural mineral material found in the Nimrud region/Ibrahim Al-Khalil village (40 km southeast of Mosul city). This is achieved through chemical analysis and X-ray fluorescence (XRF) to identify its various elemental components. Subsequently, X-ray diffraction (XRD) is employed to determine the percentage ratios of clay minerals (natural zeolites) and nonclay minerals comprising the natural mineral ore. The natural zeolite is then selectively concentrated by removing carbonates, iron, and reactive silica (amorphous silica) followed by impregnation with nickel using the compound Ni(NO₃)₂.6H₂O. The properties and characteristics of the prepared zeolites (impregnated and nonimpregnated) are investigated using XRF, XRD, Brunauer–Emmett–Teller (BET) surface area analysis, scanning electron microscopy (SEM), as well as thermogravimetric analysis (TGA). The analysis reveals its compliance with both chemical and crystalline specifications of zeolites, in addition to good surface area, selective porous channels, and thermal stability.

用本地矿石制备接镍沸石及其催化性能研究

该研究包括对在Nimrud地区/Ibrahim Al-Khalil村（摩苏尔市东南40公里）发现的当地天然矿物材料的调查。这是通过化学分析和x射线荧光（XRF）来识别其各种元素成分来实现的。随后，利用x射线衍射（XRD）测定天然矿物矿石中粘土矿物（天然沸石）和非粘土矿物的百分比，然后通过去除碳酸盐、铁和活性二氧化硅（无定形二氧化硅），然后用Ni(NO3)2.6H2O化合物浸渍镍，选择性地浓缩天然沸石。采用XRF、XRD、BET （brunauer - emmet - teller）比表面积分析、扫描电镜（SEM）和热重分析（TGA）对所制备的沸石（浸渍和未浸渍）的性质和特征进行了研究。分析表明，它符合沸石的化学和晶体规格，除了良好的表面积，选择性多孔通道和热稳定性。
