Abstract
Impregnation resulted in the oxidation of Fe2+ to mixed Fe3+/Fe2+ (magnetite) oxide forms during pyrolysis. A reaction sequence was proposed in which Fe-sulphates were incorporated with an ammonia catalyst. Sulphur became ubiquitous in both inorganic and organic forms, and additional minerals also formed. Stable aromatics and separation of holo-cellulosic and degraded lignin volatilisation phases were catalysed, and carboxylation was inhibited. Concentrations of C fluctuated more substantially, before stabilising at high HTTs. Pyrolysis temperatures of 450â¯Â°C and above appear to maximise stable C concentrations.These observations indicated that this treatment may yield agriculturally engineered chars with enhanced redox potential, more neutral pH, and a range of nutrients.
