Title:
青酸の製造方法及び青酸の製造装置
Document Type and Number:
Japanese Patent JP7294401
Kind Code:
B2
Abstract:
Provided are a method for producing hydrocyanic acid and a device for producing hydrocyanic acid, which can improve a yield of the hydrocyanic acid in a vapor phase contact ammoxidation reaction of methanol. The method for producing hydrocyanic acid includes a step of obtaining hydrocyanic acid by a vapor phase contact ammoxidation reaction by supplying a raw material gas including methanol in a fluidized bed reactor (1) through a raw material gas disperser (7) disposed in the fluidized bed reactor (1) and bringing the methanol into contact with ammonia and oxygen in the presence of a metal oxide catalyst, in which the raw material gas disperser (7) has one or more pores for releasing the raw material gas into the fluidized bed reactor (1), and the number of pores per unit cross-sectional area of the fluidized bed reactor (1) is 10 to 45 pieces/m2.
