Design and management of conventional fluidized

When the bed is fluidized, the individual sand granules are freely supported and tumble with the flow of water. The relative amount of sand bed expansion is dependent upon the density, shape and diameter of the particles, and the velocity of water (as discussed in the next section).

BUBBLING FLUIDIZED BED REACTOR - Chemical

A fluidized bed consists of a bed of particles that's unbroken fluidized by the continual upward flow of a gas. Typically, the process consists of a vertical cylindrical tube with a perforated distributor plate at the lowest. Some material in particulate type (usually sand) is placed within the tube, and gas flows from the distributor plate

Comparative study of fluidized-bed and fixed-bed reactor

2016-1-4 · Fluidized bed and f ixed-bed reactor traits analysis The above results proposed that fluidized-bed reactor appeared to be more in favor of CH4 -selectivity in syngas methanation. However, in catalytic reaction, fixed-bed reactor has the unparalleled advantage due to controllable residence time, easy operation, as well as shortening development cycle.
