Development and evaluation of a microreactor for the reforming of diesel fuel in the kW range

The development and evaluation of a reactor based on microchannel technology for the reforming of diesel fuel is reported. The reactor itself was based on an integrated reformer/burner heat exchange reactor concept. 38 h of diesel reforming was performed at temperatures above 750 °C and at various S/C ratios, down to a minimum of 3.17, up to an electrical power equivalent of 5 kW. Over 98% total diesel conversion was observed at all times over the testing period. Variation of experimental parameters such as O/C and S/C ratios are critical for optimum operation of the reformer.
