Kinetic Study and Model Development for Cumulative Biogas Production from Cattle Dung

Biogas is made up of methane, carbon dioxide, and traces of numerous trace of elements. It is created through the anaerobic digestion of organic materials, such as cattle manure, and is dependent on a number of parameters impacting the population and activity of the bacteria that make biogas. Temperature is one of the many variables that affect biogas production from cattle manure.

The effect of temperature on biogas production from cattle dung was investigated at temperatures ranging from 35°C to 55°C, with each step of 5°C. The effect of temperature on the rate of biogas production from cattle dung is evaluated using a mathematical model developed in this study.

The temperature impact is added to the modified Gompertz model to create the new mathematical model. The new model was found to be capable of predicting biogas production from cattle dung at temperatures ranging from 35°C to 55°C. The results of the new model are found to be highly correlated with the experimental data of the current study.
