Syngas Production from Heavy Liquid Fuels Achieves 75% Conversion Efficiency

Reforming heavy liquid fuels like diesel and kerosene in an oxygen-depleted, inert porous medium can efficiently convert them into syngas, a valuable fuel source.

Apollo (University of Cambridge) · 2010

Key Findings

01Up to 75% conversion efficiency to syngas was achieved with n-heptane in alumina beads at an equivalence ratio of 3.
02Heat losses were reduced to approximately 10% under specific thermal loads and equivalence ratios.
03Diesel, kerosene, and biodiesel were reformed to syngas with over 60% conversion efficiency in a zirconia foam burner.
04Soot particle formation was observed for all fuels above an equivalence ratio of 2.0.
