dc.description.abstract | The optimal pretreatment condition of coconut husk by physicochemical methods for biogas production was investigated. The coconut husk was dried and ground into powder (~0.1 nm) and was then determined for chemical contents such as cellulose, hemi-cellulose and lignin, respectively. The chemical contents of cellulose, hemi-cellulose and lignin were 35.67±2.02, 7.41±0.69 and 40.82±0.62 w/w, respectively. After pretreatment with 4 different methods, the results showed that the pretreatment of sodium hydroxide 30 % (w/w) gave the highest chemical contents of cellulose, hemi-cellulose and lignin with 43.30±0.03, 33.69±7.48 and 27.36±0.03 w/w, respectively. As for the biogas production, the result showed that the ratio of coconut husk to cow dung of 1:4 with C:N ratio of 23:1 gave the highest cumulative biogas of 442.6 ml for 30 days. Methane and carbon dioxide contents were 46.1 and 23.1 %. Moreover, the removal percentages of the total solids (TS), volatile solid (VS), suspended solids (SS) and COD were 69.3, 32.5, 50.0 and 58.4 %, respectively. The coconut husk could be used as an alternative material for the application of biogas production with cow dung in the near future. | en_US |
