Synthesis and characterization activated carbon using a mix (asphalt- sulfur Waste) supported nickel Catalyst for hydrogenation process

Abstract

 In this work, the preparation of activated carbon using low-cost materials ( asphalt : sulfur waste) through thermal fusion carbonization and the activation by microwave technique. Carbonization was carried out at temperatures ranging from 240 ± 5°C, followed by hot steam and microwave activation to improve porosity and surface structure. The synthesized  of activated  carbon exhibit the presence of pores on the surface with various diameter ranges (from 2.2 to 2.3 μm).  an active surface area of 203.42m² g⁻¹, pore volume 0.03-0.08 cm³/g and shows a high adsorption capacity for dye. Evaluations included the adsorption of methylene blue and iodine dyes as key indicators of surface activity and pore size. Sample C6 demonstrated excellent adsorption performance, surpassing, in some cases, commercial carbon.
