KINETICS OF BIOGAS GENERATION USING DOMESTIC WASTES AS FEEDSTOCK
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
Anaerobically, biogas was generated from decayed organic substances through fermentation induced by microbial activities in the bio-reactor. This study reports a pilot project on the kinetics of the biogas produced from fresh pumpkin straws. The study was based on time at constant temperature of 35 oC and pH of 7. The result showed that 0.8 cm3 biogas yield was made within the first six days of the production. The yield continuously increased till the 19th day with a maximum yield of 3.0 cm3 but declined to a zero level on the 21st day. Further recovery of the gas yield was achieved by diluting the acidic slurry of the slurry with 380 cm3 of water. The yield increased from 3.0 cm3 to 3.7cm3 on the 22nd and 23rd day respectively and later decreased to 3.2 cm3 and it then leveled at 3 cm3 in the rest of the production period. The biogas production followed initial rate Pseudo second order reaction with an average specific rate constant of 0.3212 cm-3 day-1 .
