Abstract

See full text

A fluidized apparatus contains a double-trapezoid structural member. These fluidized apparatuses are used in the nitro compound hydrogenation reaction process. The fluidized apparatus includes a shell, a gas distributor, and an inner chamber defined by an inner wall of said shell and an upper surface of said gas distributor, in the middle region of said inner chamber is disposed a perforated plate, the perforated plate comprise an outer edge region and a center region, assuming the opening rate of the outer edge region is A1 (the unit is %), assuming the opening rate of the center region is A2 (the unit is %), then A1/A2=0-0.95.
