Low Power Non Thermal Plasma Assisted Removal of Impurities for Biogas Purification

There has been increased interest in use of biogas as a renewable energy source for environmentally benign power sources such as fuel cells. The stringent fuel quality requirements of the fuel cell however requires using multiple, complex purification steps for achieving the desired fuel quality. It is hence important to develop a simple cost and energy effective way to purify the biogas to the desired fuel quality for fuel cell. Lynntech proposes an integrated approach to remove these harmful impurities in biogas with a low maintenance, low pressure non-thermal plasma assisted catalytic process. The identified fuel cell system is Lynntech"s high temperature proton exchange membrane fuel cell (HT-PEMFC) technology. The target of the proposed work is to identify a single compact, low pressure, energy efficient system that will suffice for removing all the harmful impurities for the downstream fuel cell system. The proposed plasma system will also easily integrate with downstream methane reformation system for hydrogen production for fuel cell application.
