Utilization of biomass (Rice straw) to produce activated charcoal through single stage pyrolysis process.

Abstract

The average cost generation of activated carbon from biomaterials is relatively low as compare to the cost of industrial prepared activated carbon, recent experimental work mainly focuses on the low cost and efficient substitutes to the pre-existing commercial methods and finding economical process that can subsidize the sustainability to environment and provide benefits for further commercial use. In this research Raw material (Rice Straw) was used to produce activated carbon, process was initially started with washing of raw material to eliminate dirt impurities with distilled water and de-moisturized it in an oven for 24 hours at 105 ⁰C. Then dried mass (DM) was impregnated with the activating agent MgCl₂ with 1:1 and kept for 2 hours at room temperature and dried for 48 hours in an oven for activation. The treated material was carbonized by pyrolysis process in muffle furnace for 2 hours at 550 ⁰C and the final product was kept in desiccator for further use. Freshly produced activated carbon Surface morphology was characterized by X-Ray diffraction (XRD), scanning of electron microscopy (SEM) & surface functional groups were analyzed by furrier Transform Infrared Spectroscopy (FTIR). Iodine number and methylene blue.
