Development of Biogas Quality Upgrading Equipment for Community

Abstract

The objective of this study is to establish and to test the biogas quality improvement system. In order to improve the quality of biogas, the defector is designed for detection the hydrogen and the humidity by using rusted steel and activated charcoal. Three times test a day for three days are collected at 7:00 in the morning, 1.00 in the afternoon and 7:00 in the evening. The measurement factors include temperature, moisture content, biogas flow rate, hydrogen sulfide content, and methane content. The results found that the efficiency of 0.5 kg activated charcoal can be eliminated 100 percent for hydrogen sulfide and 46.90 percent of moisture content. The increasing of the amount of charcoal from 0.5 kg to 1 kg and 2 kg shows that the performance of moisture content reduction is increased. Also, the activated charcoal is able to trap moisture well through the time and rapidly decrease later. Therefore, it is suitable to apply in short time cooking households.
