Gas distribution system for a two-zone fluidized bed reactor
Is Version Of
The present invention provides an improved method for constructing a gas distribution system which creates two distinct reaction zones within the same fluidized bed. The invention provides for the distribution of one type of gas at the bottom of the fluidized bed and a second type of gas at a higher level in the fluidized bed. The system is constructed of a plurality of modular units constructed entirely of refractory materials. The modules are fitted and linked together to form a grid, the size of which can be varied to accommodate different reactor sizes.
