Abstract
A chemical looping gasification method for iron-rich sludge is provided, in which the iron-rich sludge is sequentially subjected to pressure filtration and crushing to obtain an iron-rich sludge particle with a moisture content of 40-50%. The iron-rich sludge particle and an iron-based oxygen carrier are subjected to a chemical looping gasification reaction in a fluidized bed reactor to form a sludge ash as a supplementary oxygen carrier. The chemical looping gasification is then performed with the supplementary oxygen carrier, the oxygen carrier and unreacted iron-rich sludge particle, while the iron-rich sludge gasification process, the produced syngas is rich in hydrogen and could be used as fuel.
