CHARACTERIZATION OF CHEMICAL STRUCTURE FOR BASE ACTIVE METAL (NaOH) ON PALM OIL INDUSTRIAL WASTE

The development of solid catalyst has been investigated by considering the development of the chemical structure. In this study, solid catalyst was produced by using potassium hydroxide (NaOH) as an active metal on three types of support, Magnesium Oxide (MgO), Oil Palm Kernel Shell (OPKS) and Oil Palm Ash (OPA). Catalysts was study at different temperature (300 °C, 400 °C, 500 °C) and time (4 and 5hr) calcination via impregnation process. The catalysts were subjected to the characterization analysis using Chemisorption, Thermogravimetric analysis (TGA) and X-Ray Diffractometer (XRD) . C hemisorption results showed weaker active site developed at higher calcination temperature while TGA results showed higher thermal stability at longer calcination time. In addition, the intensity of the XRD peaks also increased with increasing calcination temperature. The result showed that agricultural waste from oil palm industry could be tune as a potential support to produce active catalyst and can be applied in related chemical reaction.
