Fluidized-bed photocatalytic nitrogen fixation reactor

Abstract

The invention discloses a fluidized-bed photocatalytic nitrogen fixation reactor. The fluidized-bed photocatalytic nitrogen fixation reactor comprises a cylinder, wherein the upper end of the cylinderis connected with a flat plate end socket through a flange, the lower end of the cylinder is connected with an oval end socket, a liquid outlet is formed in the cylinder, a gas outlet is formed in the flat plate end socket, and a liquid inlet and a gas inlet are formed in the oval end socket; and a plurality of circular partition plates are evenly distributed in the cylinder, LED lamp beads are installed on the partition plates, every two partition plates are connected through a supporting pipe, and a spherical micro-pearlescent catalyst is placed between every two partition plates. The fluidized-bed photocatalytic nitrogen fixation reactor disclosed by invention overcomes the problems of a small contact area and insufficient contact between reactants and catalysts in existing equipment and the problem of difficulty in catalyst recovery; the LED lamp beads are used as a light source and are arranged on the partition plates in a concentric circle manner, so illumination is uniform, anda light energy utilization rate is high; and the reactor is simple in structure, the LED lamp beads and the spherical catalyst are easy to disassemble, assemble and replace, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of catalytic reaction equipment, in particular to a fluidized bed photocatalytic nitrogen fixation reactor. Background technique [0002] Ammonia is an indispensable and important raw material for industrial and agricultural production in modern society. At present, industrial ammonia synthesis is carried out through the Haber process, which requires high pressure (15-25MPa) and high-temperature (673-873K) conditions, and the process is complicated, and the raw material is pure N 2 and pure H 2 , consumes a lot of energy, and also produces a large amount of carbon dioxide, so it is of great significance to seek new technologies for the synthesis of ammonia that are environmentally friendly and energy-saving. [0003] Compared with industrial ammonia synthesis technology, photocatalytic nitrogen fixation (synthetic ammonia) technology has significant advantages: (1) It can be carried out under normal temper...
