主 题：Biogas Media Materials Anaerobic Hard and Soft Woods Slurry
摘 要：The paper investigates the effects of the quantity of media materials with simple appraisal on biogas yields between hard and soft wood subjected to the same atmospheric condition in the Ado-Ekiti, Nigeria, between October 2009 and June 2010. Sixteen digesters were used and the mechanical grinding of cassava peels was done in a clean mortar and pestle. Specific grammes of cow dung and cassava peels (200 g, 150 g, 100 g and 50 g) were seeded with four substrates (woods) mixed up with 1200 cm3 of distilled water respectively. The appropriate ratios of the prepared slurries were transferred into different digesters for bio-degradation process which is third-fourth full with the aid of a funnel, and the tubes were passed into a measuring cylinder as a gas collector?inverted over acidified water in a plastic vessels. The volume of biogas produced ranged from 6964 cm3 to 13,185 cm3 by Mahogany, and Iroko ranged from 5340 cm3 to 10,250 cm3 were obtained for both hard woods used. Likewise, the volumes of gas produced by soft woods were from 2465 cm3 to 6445 cm3 by?Obeche and 3430 cm3 to 6990cm3 by Araba. The results showed that, the highest percentage of the seedling media materials (33% each) on the substrates (cassava peel and cow dung) produced the highest biogas with 2800 cm3 of Mahogany, 2400 cm3 of Iroko, 1200 cm3 of Araba and 1130 cm3 of Obeche woods respectively. It was established that, the rate of biogas yields is directly proportional to the quantity of the seedling materials to obtain a reliable results as an alternative renewable energy.
