Abstract
Abstract Material increases in throughput and output of batch-type reactors are obtained by avoiding operational time losses in dumping and filling and startup. The improvements are achieved by a flexible divider which extends upwards from the bottom of the unit and which moves from one side of the reactor to the other to increase and decrease, respectively, the volumes of the sections of the reactor. One section can be functional while the other section is being emptied and refilled. The combined output of the sections approaches the output of a continuous reactor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
37 words
An apparatus according to claim 1 wherein said flexible divider is disposed within said chamber so that at least one vertical edge of said flexible divider can move along adjacent to the inside surface of the chamber.
Claim 2
Dependent Claim
117 words
An apparatus according to claim 1 further including a perforated solids support plate positioned horizontally in the lower portion of said chamber, each said section is a fluidized bed reactor, said flexible divider has a vertical height extending from immediately adjacent to the upper horizontal surface of said support plate to appreciably above the operating level of said fluidized beds and said support plate forms the respective bottoms of said beds, fluidizing gas inlet below said plate, gastight means for feeding solids at a controlled rate into each said section, fluidizing gaS outlet in the upper part of said chamber, and solids withdrawal means in communication with the lower portion of each said section of said apparatus.
Claim 3
Dependent Claim
61 words
An apparatus according to claim 1 wherein said flexible divider has an S-shape when in said central position, each vertical edge of said flexible divider is positioned essentially in opposition within said chamber and remains in such position during said flexing, and said horizontal width of said flexible divider is at least equal to one-half the internal circumference of said chamber.
