In this contactor solid particles slide down along the inclined perforated plates by the upflowing gas. This structure, called as 'z path moving bed', has some of the advantages of both moving and fluidized beds. The discharge rate of solid particles, inclination angle of the perforated plate, aperture ratio of the perforated plate, size of particles and gas velocity were chosen as parameters for experimental conditions.
