Production of activated carbon and furfural from biomass

Abstract

Results and Discussion: The chemical activation of Pinewood is done using various active agents such as ZnCl2, KOH, and KCl, followed by Pyrolysis, which is performed in the absence of O2 and under vacuum conditions to increase surface area and improve interactive porosity. Carbon made from waste biomass is less costly as is readily available as biomass waste. Activated carbon produced with the help of this process has a greater surface area of 969.075 m2/g. Similarly, Acid hydrolysis is carried out in dilute Hydrochloric Acid (HCL) at a specific temperature and reaction time. The experimental work is performed in a batch reactor system. A result shows maximum furfural (2.5 M HCL) yield of 7.954 % is obtained for Corn Cob compared to pine wood. newline newlineConclusions: Generally, the BET surface area range is from 500 1500 m2/g, and pore volume is 0.3 0.8 cm3/g. The Resultant product Surface Area ( BET ) shows that at 550 0C, the highest surface area (activated carbon) is 969.075 m2/g. Pore volume is 0.5 cm3/g. Elemental Analysis shows a higher value of % Fixed carbon content in the product if it is heated at 550 oC than other temperature ranges. By studying and comparing characterization like Elemental Analysis, Powder XRD, Surface Area Porosity Measurement (BET), Particle Size Analysis and FESEM, activated carbon produced from Pinewood with the help of Chemical Activation and pyrolysis process at 550 0C temperature has given a satisfactory result. Processed carbon from Pinewood can therefore be used effectively to remove pollutants from wastewater. Similarly, a good yield of 7.954 wt% furfural from Corn Cob can be proven by various tests. Environmenl and economical point of view furfural production from biomass could provide a less expensive alternative than commercial furfural
