Abstract

Bone is one of the wastes result in environmental pollution and public health issues if it is thrown directly into the environment. The aim of this research was to study the characteristics of activated charcoal of activated sulfuric acid goat bone. The process of making activated charcoal of goat bone included two stages of process, herein consisted of first carbonization process of goat bone at temperature of 700  C for 20 minutes to produce goat bone charcoal. The second process is chemical activation by using sulfuric acid activator at various concentrations of 1N, 2N and 3N for24 hours. The results showed that the best activated charcoal characteristic of sulfuric acid was at 3N sulfuric acid concentration, 0.289% moisture content, ash content of 6.4%, absorption capacity of Iod 983 mg / g, volatile matter 15,017, fixed carbon 82.013 and spectra FTIR of activated carbon showed spectra of absorption band at wave number 3546,143 – 3604,135 cm-1 on vibration of group -OH, with intensity 76%. Overall, the results revealed that the quality of activated charcoal of goat bone isstill eligible of the values recommended by SNI-06-4253-1996 about the quality of activated charcoal.

Abstract

This study aims to study the efficiency of CO and SO2 gas absorption in motor vehicles emission using activated banana leather bark (Musa acuminate L). The carbon was prepared though consists of a banana skin carbonation process at a temperature at 450 o C for 1.5 hours and activated carbon activation process using H2 SO4 activator at concentrations of 1 Nfor 1, 2 and 3 hours.The motor vehicle emission absorption process uses an adsorption tube which has been loaded activated carbon and connected to the exhaust for 5 minutes. The test of activated carbon characteristics studied were absorption test I2, FTIR test and SEM test. The results showed that iodine absorption was 914 mg / g. The FTIR spectra of activated carbon showed absorption band spectra at wave number 781,17 - 3624,25 cm-1 on vibration of group -OH, with intensity 77,85%. The SEM results show the addition of pore size before and after activation of 1.131 μm and 15.015 μm. The carbon CO gas absorption efficiency is 25% and Gas SO2 is 40%

Abstract

Livestock waste, such as bone, has always been ineffectively exploited. Bones contain organic compounds that can be further processed into usable products such as charcoal and activated charcoal. This research, therefore, aims to identify the optimum temperature conditions suitable for the manufacturing process of activated charcoal from goat bone waste using thermal activation. The study uses a two-stage process which is carbonization and thermal activation. Activation temperatures used in the process were at a temperature of 500 °C, 600 °C and 700 °C for three hours. The results of the characteristics of activated charcoal thermally produced in  this research met the Indonesian National Standard 06-3730-1995 about technical activated charcoal, and the  optimum conditions were at an activation temperature of 500 °C. These characteristics include the values of the water content at 1.210%, ash content at 2.034%, absorption of iodine 926 mg/g, volatile matter of 0.434% and fixed carbon of 96.616%.
