The use of gasoline for primary energy consumption can reduce crude oil, contained in the earth. The development of alternative fuels such as biogas and biofuel is very critical to overcoming this problem. Biogas requires purification to remove some contaminant particles that interfere with the combustion process. The packed column is generally applied to absorb and separate gas and liquid mixture. It is more efficient due to the liquid flows down the column of steam naturally without the supply of energy from outside the system. This study focuses on determining the effect of the packed column biogas purification process. Biogas is applied as an alternative fuel in spark-ignition engines (SIE). The test is carried out using a chassis dynamometer to obtain power and torque data. The use of the packed column for biogas fuel purification can produce higher performance compared to unrefined biogas. The unrefined biogas still contains impurities that can interfere with the combustion process. This condition is proven by measuring the power and torque of the vehicle on the chassis dynamometer, where the filtered biogas produces higher power and torque. Tests were carried out both using the packed column and without the packed column. Variations from speed to torque, to power, to SFC and BMEP are considered. In this study, validation is in good agreement with previous studies. Overall, the results show that the average error between using the packed column and without the packed column for torque, power, SFC and BMEP is increased by approximately 7 %. Purification of biogas using the packed column using Ca(OH)2 can bind CO2 and obtain pure methane gas with a higher heating value. In conclusion, the packed column for biogas purification as fuel for motorcycle injection systems can be applied

 Biogas is one of the alternative energy sources that are environmentally friendly, inexpensive, easily available, renewable, and can be used as a substitute for gasoline for motor gasoline. For the use of biogas in the motor gasoline is necessary to improve the quality of biogas that is more optimal use of biogas when used as fuel.This study aims to determine the reduction of carbon dioxide (CO2) during the purification of biogas by using absorber Ca (OH)2 to the elevated levels of CH4 in biogas and its effect when testing the performance of the motor fuel, which indicate the performance of the motor fuel is the torque, power and effective specific Fuel Consumption effective. In this study, the biogas will be purified by varying the flow rate is var I (5 liters / min), var II (10 ltr / min) and var III (15 ltr / min), and biogas purification degan best quality results will be compared with biogas before purification by way of testing the motor performance in round 1500 rpm, 2500 rpm,3500rpm and 4500 rpm.The result showed that the purification of biogas menggunan Ca (OH)2 at a rate var II (10 ltr / min) produced the best biogas CH4 content of 91.0%, better than the variations I and III variations, and the results of performance testing of the motor fuel showed improvement menghasillkan better quality. Judging from rotation 4500 rpm for prior purification 5.9399 Nm torque, power and SFCe effective 2797.7079 W 0.000164 (kg / jam.W), whereas after purification 6.5821 Nm torque, effective power 3100.1628 W and SFCe 0.000113 (kg / jam.W)

Biogas Purification

Biogas purification which is the removal of impurities so as to improve the efficiency of gas produced, ensure the safety of end users and prolong the life of the equipment cannot be neglected. This paper is focused on the design and performance evaluation of AD system biogas purification filter. Three different conceptual designs were generated from possible design consideration, feasibility study and preliminary test and with the help of decision matrix; the best conceptual design was selected from which the purification filter was fabricated. The selected concept for detail design was a transparent polyethene cylindrical purification filter fitted with local iron sponge containing activated charcoal and local potash. The reagents were arranged in this order; local potash for the removal of water vapour and carbon dioxide followed by activated charcoal which serves as a purifying agent for hydrogen sulphide. The results obtained showed reduction in percentage composition of hydrogen sulphide (H2S), carbon dioxide, and water vapour. On the other hand, there was an increase in percentage composition of methane (CH4) which is an indication of improvement in methane production after purification. The outcomes of the results obtained were satisfactory and the combination of local potash and activated charcoal was adequate for biogas purification.
