New Method for Catalyst Powder Manufacturing Based on Solvent Combustion

A new method for the synthesis of fine catalyst powders is presented. Catalyst precursors are dissolved in an ethanol-water mixture which is burned through a nozzle-type burner. As a result, catalyst powders are formed and removed from flue gases through a filter. LaMnO₃ catalysts for the catalytic combustion of methane have been prepared, characterised (TEM, XRD) and compared with a reference manfacturing method (the citrates one) showing promising, though improvable, results. This revised version was published online in August 2006 with corrections to the Cover Date.
