Abstract: PURPOSE: A micro-macro channel reactor is provided to improve the performance per volume of the reactor and to improve the distribution, the flux increase of reactants and the efficiency of the reactor. CONSTITUTION: A micro-macro channel reactor includes an upper end plate(20), a lower end plate(60), a heat exchanging plate(30), a catalyst plate(40), and a supporting plate(50). The catalyst plate is stacked to the thermal exchanged plate. The catalyst plate includes a catalyst part(41). While reactants pass through the catalyst part, the catalytic reaction of the reactants is generated. The supporting plate is stacked to the catalyst plate and provides a flow path(52) through which the reactants pass. The heat exchanging plate, the catalyst plate, and the supporting plate are stacked between the upper end plate and the lower end plate.

Abstract: Nitrogen trifluoride is produced with a high yield by the method comprising forming a fast stream of micro droplets of a fused ammonium fluoride salt by rapidly ejecting the fused ammonium fluoride salt into a reactor through a nozzle while circulating the fused ammonium fluoride salt in the reactor from a lower portion to an upper portion; and contacting micro droplets of the fused ammonium fluoride salt with fluorine gas sucked in the reactor through a suction pipe for fluorine by a negative pressure formed around the nozzle due to an ejection of the fused ammonium fluoride salt, whereby excessive generation and regional accumulation of the heat of reaction are prevented, reducing the reaction temperature by 10~30° C. compared with those of the existing methods, and a side reaction occurs only to a slight extent according to the lowered reaction temperature.

Abstract: PURPOSE: Provided is a method for producing nitrogen trifluoride NF3 at low temperature with high yields by effectively making ammonium bifluoride molten salt come into contact with fluoride. CONSTITUTION: The method comprises the steps of forming fine liquid droplets of ammonium bifluoride molten salt by spraying ammonium bifluoride molten salt in a reactor(10) from a lower part to an upper part thereof through nozzles, and making the ammonium bifluoride molten salt droplets come into contact with fluoride gas being introduced into the reactor(10) by a fluoride suction pipe(32), wherein the fluoride gas supply into the reactor is intermittently stopped and ammonia gas is introduced into the reactor(10) at that time to regenerate ammonium bifluoride in the reactor to keep concentration of ammonium bifluoride molten salt in the reactor(10) to a certain degree.
