Feasibility Study of Hydrogen Production from Compression Ignition Engine Fueled with Biodiesel-Diesel Fuel Blends via Reforming Process

摘要

This paper aim to find feasibility of hydrogen production via biodiesel fuel exhaust gas reforming. The examined process base on platinum-rhodium alumina catalyst, intend application for compression ignition engine, fuel cells and after-treatment technologies. This research are investigated the exhaust gas composition (e.g. O₂, CO₂) under different engine conditions under no modification engine. The comparison between biodiesel 50%Vol. blends with diesel 50%Vol. (DB50) fuel and pure biodiesel (B100) on combustion in conjunction with exhaust gas assisted fuel reforming in a compression ignition engine are also investigated. The result shown that pure biodiesel has the higher yield of hydrogen (11%vol.) in the exhaust gas reforming process compared to hydrogen production in DB50 (<;2%vol.). Hydrogen production showed a strong dependence on the oxygen to carbon (O/C) ratios and reforming operating temperatures. Thus, the use of pure biodiesel fuel has shown an attractive potential to produce hydrogen over exhaust gas reforming process in compression ignition engines.
