Effect of Calcination Temperature on Prepared Γ-Al2O3 as Support Catalyst
Keywords:oxidative desulfurizatio, calcination temperature, composite catalyst, friendly fuel (light gas oil)
The effect of calcination temperature on the surface properties of gamma alumina was investigated in this study, which is used as a support for multiple metal-loaded catalysts. The Sol-gel technique was used to create -Al2O3 support from aluminum nitrate as a precursor at various calcination temperatures (500, 550, 600, and 650°C). Then, for each sample, characterization tests such as X-Ray fluorescence (XRF), X-Ray diffraction (XRD), Thermal gravimetric analysis (TGA), and surface area (BET) are performed to determine the optimal calcination temperature to produce highly active composite catalyst support. It has been discovered that samples calcined at 600 and 650°C have very similar properties in terms of mechanical strength, thermal stability, crystallinity, high purity, and surface properties or morphology. However, the surface area and pore volume of 600°C are thought to be superior to those of 650°C.
