Aktif karbonlar, enerji depolama sektöründen su ve hava temizleme sistemlerine kadar pek çok önemli alanda, geniş kullanım alanına sahiptirler. Bu çalışmada, aktif karbonların, patlıcan (Solanum melongena) sapı, Muz (Musa sapientum) ve Portakal (Citrus sinensis) kabukları olmak üzere 3 farklı biyokütleden sentezlenebilirliği araştırılmıştır. Sentez için 2 saat boyunca 1200 °C'de karbonizasyonu gerçekleştirilen biyokütleler, 24 saat süreyle 4N Sülfürik asit (H2SO4) ile aktive edilmiştir. Son olarak, elde edilen bu aktif karbonlar Endonezya Ulusal Standart ölçümü sistemi olan SNI 06-3730-1995.5'e (maksimum su içeriği %15, maksimum kül içeriği %10, maksimum buhar içeriği %25 ve minimum bağlı karbon içeriği %60) göre değerlendirilmiştir. Yapılan bu çalışma sonucunda, patlıcan sapı, muz ve portakal kabuğunun su içeriği % 13.8, % 21.9 ve % 19.3; Kül içeriği %6,50, %8,50 ve %22,4; Buhar içeriği %15,5, %26,2 ve %22.8; Bağlı karbon içeriği %78.0, %65.3 ve %54.8 bulunmuştur. Sonuç olarak, Bu biyokütleler arasında, patlıcan sapının aktif karbon üretimi için en uygun kaynak olduğu tespit edilmiştir.

Synthesis of Activated Carbon from Different Biomasses

Öz

Activated carbons have an essential role and wide usage area from the energy storage industry to water and air cleaning systems. In this study, activated carbon had synthesized from three different biomass eggplant (Solanum melongena) stalks, Banana (Musa sapientum), and Orange (Citrus sinensis) peels. Carbonization has accomplished at 1200 °C for 2 hours. After that, 4N of Sulfuric acid (H2SO4) had used as an activated agent for 24 hours of impregnation. Finally, the activated carbons had optimized according to the Indonesian National Standard measurement, SNI 06-3730-1995.5 (maximum water content 15%, maximal ash content 10%, maximal vapor content 25%, and minimal bounded carbon 60%). According to result, the water content of Eggplant stalk, banana, and orange peels are 13.8 %, 21.9 % and 19.3 %; Ash content 6.50 %, 8.50 % and 22.4 %; Vapor content 15.5 %, 26.2 %, and 22.8 %; Bounded carbon content 78.0 %, 65.3 %, and 54.8 % were found. Finally, the Stalk of eggplant has provided the best biomass for producing activated carbon.
