Experimental Study on development and demonstration of hydrogen production from food waste generated biogas Share

The increase in the intake of students, constant change in consumption pattern and social behavior has increased the generation of food waste in National Institute of Technology Karnataka (NITK) Campus. A Steam Biogas Reformer (SBR) designed and developed in the present study will be used to convert the biogas generated from the food waste available in the NITK Campus into compressed Hydrogen gas. The research is intended to develop a bench scale setup for hydrogen production from methane rich biogas via Steam Methane Reforming (SMR) for primary analysis. Methane steam reforming is considered a widely available method to produce hydrogen at a large scale due to the well-developed methane infrastructures and the favorably high hydrogen to carbon ratio of methane [2]. Methane steam reforming is a strongly endothermic reaction as shown in Equation (1). It also includes the exothermic water gas shift reaction, Equation (2) which is more favorable at low-temperature conditions (200°C –550°C). The complete reforming process is described by Equation (3) as a combination of reactions Equations methane oxidation and water gas shift reactions.

The present work is compared with the results of the conventional micro reactors, advanced reaction systems and conventional fixed bed reactors and difference in the results is to be discussed for optimization of the technique. Based on the experimental and theoretical results, the bench scale is rescaled to pilot scale for commercialization purpose. Further produced hydrogen will be used in house power generation by developing hydrogen fueled generator.
