Abstract

The study of synthesizing Cr/activated palm shell charcoal catalyst by impregnation method has been done. Cr/Activated Charcoal was made using variation of chromium concentration (1%, 2% and 3%). Change in diffraction pattern in XRD analysis for charcoal before modification and after modification showed chromium has been successfully impregnated to the catalyst. The higher the chromium compound concentration used, the greater %-weight of chromium in the catalyst. It was found that the use of Cr-2%/Charcoal catalyst was able to increase the percentage of cracking liquid yield at the temperature of 550oC  as much as 62,44% compared to the percentage of liquid yield from thermal cracking was 60,1% at the same temperature. It was also observed, using the Cr/Charcoal catalyst from impregnation method is more effective than catalyst from ion exchange method. However, the density of the cracking liquid yield is not yet close to the standard density range for fuel.

Abstract

Zeolit adalah material porus dengan struktur kristal yang unik, yang memiliki kemampuan penyerapan baik terhadap berbagai jenis molekul. Daun bambu dipilih sebagai bahan baku yang ketersediaannya yang melimpah dan ramah lingkungan. Metode hidrotermal digunakan untuk mensintesis zeolit dari daun bambu dengan menggabungkan daun bambu dengan reagen NaOH. Variasi waktu sintesis dilakukan untuk mempelajari pengaruhnya terhadap karakteristik zeolite yang dihasilkan dengan variasi 2 jam, 4 jam, dan 6 jam. Berdasarkan uji XRD menunjukkan bahwa pada ZGA/Al-A1 dari data difaktogram menghasilkan zeolit mesolite, pada ZGA/Al-A2 dari data difaktogram menghasilkan zeolit 4A, dan pada ZGA/Al-A3 dari data difaktogram menghasilkan zeolit sodalit. Kapasitas adsorpsi ZGA/Al-A3 yaitu yaitu 24,92 mg/g dan efesiensi adsorpsi ZGA/Al-A3 yaitu sebesar 99,69 %. Hal ini menunjukkan bahwa zeolit dari daun bambu dapat dijadikan sebagai adsorben pada penyerapan ion logam Mn2+.
