Abstract

Telah dilakukan penelitian tentang pembuatan arang aktif dari sampah perkotaan dengan pemanasan dan steam. Proses pembuatan arang aktif dimulai dengan pirolisis sampah perkotaan menggunakan reaktor drum pada suhu 500oC selama 5 jam. Selanjutnya, arang yang diperoleh diaktivasi dengan panas dan steam menggunakan retort listrik pada suhu 700 dan 800oC , dan waktu selama 60 dan 120 menit. Hasil penelitian menunjukkan bahwa kondisi optimum untuk memperoleh produk arang aktif dengan kualitas terbaik diperoleh pada proses aktivasi dengan steam pada suhu 800oC dan waktu aktivasi selama 120 menit. Rendemen arang aktif yang dihasilkan pada perlakuan tersebut, yaitu 57,60% (w/w). Hasil karakterisasinya diperoleh kadar air 1,36% (w/w), kadar zat terbang 8,87% (w/w), kadar abu 12,27% (w/w), kadar karbon terikat 78,86% (w/w), daya serap terhadap benzena 22,51% (w/w) dan daya serap terhadap iodin sebesar 873,53 mg/g. Hasil identifikasi gugus fungsi diketahui arang aktif yang dihasilkan pada semua perlakuan masih mengandung pengotor berupa gugus OH, C=O, dan C-O. Hasil analisis dengan SEM menunjukkan bahwa perlakuan terbaik menghasilkan arang aktif dengan diameter pori rata-rata berkisar 4,8-7,7 μm.

Abstract

Oil palm shell waste has a hard structure and is difficult to biodegrade. Pyrolisis is a suitable and profitable technique for destruction of this waste. Using this technique, the oil palm shell waste can be degraded quickly and the product can be used for various purposes. The aim of this research was to find out the quality of charcoal as a pyrolysis product of the oil palm shell waste. The pyrolisis took place about 5 hours in a drum reactor, which was equipped with temperature controller device of thermocouple brand. The structure of charcoal product was characterized by Furier Transform Infra Red (FTIR) and Scanning Electron Microscope (SEM). The chemical composition was identified by py-GCMS. The average charcoal product was 38.81% (w/w). The charcoal contained 4.02% of water, 20.44% of fly materials, 17.46% of ash, 62.10% of fixed carbon, and calorific value of 6,118 calories/g. The FTIR analysis showed that the charcoal contained -OH, -C=O, and -C-H aromatic functional groups. Results of SEM analysis indicated that the charcoal had many pores, which were covered by impurities. The py-GCMS identified that the charcoal was composed of 25 compounds. Since quality standards for this type of charcoal was not available, it was compared to the quality standards of coconut shell charcoal powder according to SNI-06-4369-1996. It was found that the palm shell charcoal quality was low. However, based on the characterization results, it would still be profitable to produce briquettes and active carbon from the palm shell charcoal.

Abstract

Charcoal is possibly produced from municipal organic waste using pyrolysis reactor at a temperature of 350-510 oC for 5 hours. Parameters used for charcoal quality determination are: product quantity, water, ash, evaporated material, carbon, calorific value, iodine adsorption capacity, benzene and chloroform. The structure of charcoal is characterized by Fourier Transform Infra Red, X-Ray Diffraction and Scanning Electron Microscopy. Carbonization at ³ 405 oC for 5 hours produced well done charcoal, whereas carbonization at < 450 oC produces half done charcoal. Carbonization at 505oC produced best quality of charcoal, when compared to other treatment. The charcoal contained 2.426% water, 18.297% evapourable material, 12.22% ash, 69.48% carbon, and 6634 cal.. The adsorption capacity of the charcoal according to iodine solution and benzene gas were 379.80 mg/g and 12.37% respectively. The chloroform adsorption capacity was 11.69%, while the adsorption ability of charcoal resulted from carbonizing at 510 oC was 12.80%. The charcoal was composed of OH functional group, C-H, C-C, C-H aliphatic and C-O ether. Generally, the level and interval among charcoal crystalic layer that resulted from all carbonization treatment was not significant. Charcoal surface topography structure design showed more pore formation with the higher carbonization temperature.
