Waste Coke Oven Gas Used as a Potential Fuel for Engines

Coke oven gas (COG) is a byproduct of coking plants in steel mills which can be methanized resulting in a hydrogen-methane mixture with a volumetric fraction of roughly 55% hydrogen (roughly 13.25% by mass) and 45% methane (roughly 86.75% by mass). In order to simulate the use of coke oven gas as a fuel for engines, this study focuses on hydrogen enriched compressed natural gas (HCNG) at a hydrogen volumetric fraction of 55%, which is the same content as the methanized COG. The power, efficiency and emissions characteristics are outlined at different load conditions which will be provided for the next step electronic control, performance optimization and product development research. This potential alternative fuel has the potential not only to reduce engine emissions, but will also help reduce the waste COG produced in large quantities by factories across the world.
