Structure and Morphology of The (Ni, Co) Mo/Indonesian Natural Zeolite

Abstract

The NiMo/Indonesian natural zeolite (NiMo/ZA) and CoMo/ZA catalysts are produced through the impregnation methods. These catalysts were characterized by using X-Ray Fluorescence (XRF), Fourier Transform Infra-Red (FTIR), X-Ray diffraction (XRD), and Scanning Electron Microscope (SEM). The XRF data show that the CoMo/ZA catalyst has a large amount of metal content more than NiMo/ZA. The FTIR spectra of catalyst show a shift of asymmetric stretching of TO4 group to a larger wavenumbers than the FTIR spectra of ZA. Meanwhile, the metal phase in the CoMo/ZA catalyst is CoO and MoO3, and the metal phase in the NiMo/ZA catalyst is NiO and MoO3.

“…In zeolite, this shift occurred due to decreasing of Al atoms in zeolite framework in the dealumination process by HCl; therefore, the distance between the Al atoms will be further away, and Al atoms interaction will decrease, and it can be easier to move. This is similar to Ichsan et al [19] that the shift of asymmetric vibration occurred after the impregnation of Ni into zeolite, and the band at 1045.46 cm -1 shifted to 1092.72 cm -1 for zeolite and NiMO/ZA, respectively.…”

“…In Indonesia, natural zeolite reserves are more than 205.82 million tonnes. The most abundant zeolite deposits in Java are Central Java (Wonosari, Klaten), West Java (Bogor, Tasikmalaya, Sukabumi), and East Java (Bayah) 7) .…”
