A study of catalytic EGR reformer in a diesel engine.

TL;DRAbstract

In order to extend the applicability limits of Exhaust Gas Recirculation (EGR), the concept of catalytic EGR reformer has been theoretically investigated. A catalytic EGR reformer system consists of a partial oxidation reactor placed in an EGR loop and produces gaseous fuel consisting of hydrogen, carbon monoxide and carbon dioxide on demand by catalytic reforming of diesel fuel on a precious metal based catalyst. Since the fuel reforming takes place in the exhaust loop, it provides a means to recover some of the thermal energy of the exhaust. This research was a theoretical attempt to identify regions of effective operation of the catalytic EGR reformer based on energy efficiency analysis of the reformer system. The energy efficiency analysis was performed using Synthetic Atmosphere Engine Simulation (SAES) and CHEMKIN software. In this study, ways to utilize the thermal energy and surplus oxygen of exhaust gases to produce gaseous fuel in a catalytic EGR reformer system were investig
