Effect of substrate variation on biomethane production at pilot scale


Rachana C Acharya, Usha Mukundan

Biomethane refers to the gas produced by the biological conversion of organic matter in the absence of oxygen. The direct benefits gained from biomethane is its use as an alternate and pollution free fuel. In the present study attempt has been made to design a small unit of biogas reactor so as to have a convenient model for determining the quantitative effect of substrate variation on the amount of gas produced in a biogas unit. The substrates chosen for biogas production were different types of waste products such as waste grain flour obtained during cleaning of flour mill, oil-seed coat powder, spent nutrient broth and paper pulp. The substrates were compared with respect to the amount of gas produced (water displacement technique), the amount of methane content of the gas produced (gas chromatography) and by the Carbon Nitrogen ratio (C:N). Grain Flour having minimum C:N ratio 27:1 and present in finely ground form showed maximum gas production of average 3.2L and had maximum percentage methane content (66.3 %).
