Insights into Structure, Morphology and Reactivity of the Iron Oxide Based Fuel Borne Catalysts

Abstract

Iron-based FBC additives with a different length of the organic stabilizing ligands: undecylenic acid (C11) and oleic acid (C18) were synthesized. A physicochemical characterization of the materials structure and morphology was performed by means of Raman spectroscopy, electron diffraction and TEM imaging. It was found that the reactivity of iron-based fuel borne catalysts depends on the length of the organic disperser and the size of the formed hematite nanoparticles. Reactivity tests performed in soot oxidation reaction both at a laboratory scale and in a commercial light oil burner revealed that the C11 stabilizer is more efficient than the C18 one in decreasing the emission of CO and soot particles.

“…Dodatki FBC, oprócz tego, że muszą być skuteczne, to muszą również być stabilne w paliwie, dlatego są to organorozpuszczalne związki zawierające tlenki metali (jednym z najpopularniejszych jest żelazo) [11,12,14,17,18]. Stężenie stosowanych dodatków FBC wynosi zazwyczaj od 30 do 120 mg/kg.…”
