POTENTIAL FOR PRODUCTION OF ACTIVATED CARBON FROM Jatropha carcus FRUIT SHELLS | Journal of .....

The goal of this study was to convert Jatropha carcus (JC) into activated biochar (AC). Carbonization of JC seed shells at 500°C resulted in a 90% char output. Sulfonation was used to activate the char. The pH, ash content, moisture content, and adsorption capacity of the activated carbon generated were all measured. Using an iodine number test, the sample's internal surface area was discovered to be 431 mg/g at 500°C, with 9.32 percent ash content, 2% moisture content, and a pH of 5.80. Soaking, drying, crushing, sieving, carbonisation, sulphonation, water washing, acid recovery, and long-term drying and storage were all used to make AC from JC. A preliminary cost estimate for the proposed method for a factory that can process 2500 kilogramme of JS per day to create 600 kg of AC was presented. An economic analysis was conducted, which revealed that the project is viable, with a return on investment of 24% and a payback period of 4.2 years at 75% plant utilisation for a unit cost of $2.80 per kg.
