2.2. Equipment
A schematic representation of the RESS equipment is given in Fig. 1. Further details of the equipment are described in Section 2.3. Two different RESS-fluidized bed combinations were explored, one of a conical-cylindrical Wurster-type geometry (RESS-WTS) and one based on a cylindrical geometry operating as a bubbling fluidized bed (RESS-BFB) (Fig. 1).
