Selective conversion of coal nitrogen to N2 with iron

摘要: Brown coal with iron catalyst precipitated from FeCl 3 solution has been pyrolyzed in He or H 2 at 600-900 °C a fluidized bed reactor. The presence of the loadings 3-7 wt % changes dramatically fate nitrogen during pyrolysis 900 °C; 50-60 is readily converted to N , resulting low residual char. Changing fluidizing gas shows no significant effect on conversion . It probable that ultrafine particles around 50 nm reduced state are responsible for present removal
