PROCEDIMIENTO Y DISPOSITIVO PARA LA COMBUSTION DE BIOMASA SIN EMISIONDE DIOXIDO DE CARBONO

摘要

The invention relates to a device and a method for biomass combustion and simultaneous CO 2 capture for capturing the CO 2 generated in said combustion to generate a substantially pure CO 2 stream (9) which can be subsequently stored. The device comprises a combustor-carbonator reactor (a) which is fed with biomass and air; at least one solids recycling cyclone (b, c) which separates solids (5) returning to the combustor-carbonator and from which there exits a solids and gases stream (4). The device comprises a calciner B which regenerates CaO, a fluidized bed (d) and means for feeding fresh CaCO 3 (12) and for purging solids (11).
