Adsorption of 1-propanethiol on Co and Cd modified, synthetic (3A, 4A and 13X) zeolites were studied by FTIR (Fourier Transform Infrared) spectroscopy and SEM-EDX (Scanning Electron Microscope-Energy Dispersive X-Ray) graphics. Amount of metal cations on mentioned zeolites was measured by AAS (Atomic Absorption Spectrometer). Based on divalent cations of zeolites, it was assumed that cations ma...

This paper focuses on the laboratory experiments of low-temperature adsorption CO2 at elevated pressure and validation our mathematical model with data obtained. The numerical approach uses fitting isotherm parameters sensitivity analysis influencing breakthrough curve shape onset time. We first evaluate results for zeolite 13X. Then, we use obtained to design a dynamic predict profile. Experim...

In this work we aimed to optimize the production of extracellular polymeric substances (EPS) by an Arthrobacter viscosus biofilm supported on 13X zeolite to be used in the biosorption of Cr(VI). The optimization parameters were agitation rate, work volume, pH and glucose concentration. Following the optimization of EPS production, the biofilm was used in the biosorption of hexavalent Cr from li...

The research discussed the possibility of adsorption Brilliant Blue Dye (BBD) from wastewater using 13X zeolite adsorbent, which is considered a byproduct production process potassium carbonate Iraqi potash raw materials. adsorbent was prepared and characterized by X-ray diffraction that showed clear match with standard zeolite. crystallinity rate 82.15% crystal size 5.29 nm. surface area pore ...

Sub-nanometer zeolite 13X-supported Ni-ceria catalysts were synthesized for CO2 methanation. XRD and SEM results show the structure morphology of 13X after impregnation calcination. Ce loading affected catalysts’ metal dispersion, reducibility, basicity acidity, thence their activity selectivity. STEM-EDX elemental mappings showed that Ni are predominantly highly dispersed. has a positive effec...
