Kinetics and Process Studies of the Potential for Transformation of Biogas to Biomethane and Liquefaction using Cryogenic Liquid for Domestic Applications

The present work dealt with the generation, purifying and liquefaction of biomethane to improve energy density using local materials for domestic applications. Cow dung was sourced at JKUAT dairy farm experiments were conducted Bioenergy laboratory biogas generated in scale 1 m3 bioreactors. Experiments done triplicates repeated under different conditions get optimal conditions. results showed that enhanced cow substrate displayed an improved fermentation process increased yields. Purified optimized methane content from 56% ± 0.18% raw 95% 0.98% which ideal liquefaction.
