Method for producing hydrocyanic acid and apparatus for producing hydrocyanic acid

摘要

Providing a method for producing hydrocyanic acid and an apparatus for producing hydrocyanic acid capable of improving the yield of hydrocyanic acid in a gas phase contact ammoxidation reaction of methanol. A source gas containing methanol is supplied into the fluidized bed reactor 1 through a source gas disperser 7 disposed in the fluidized bed reactor 1, and the methanol is brought into contact with ammonia and oxygen in the presence of a metal oxide catalyst, Including the step of obtaining hydrocyanic acid by catalytic ammoxidation reaction, the raw material gas disperser 7 has at least one hole for discharging the raw material gas into the fluidized bed reactor 1, per unit cross-sectional area of the fluidized bed reactor 1 The number of holes is 10 to 45 / ㎡, the method for producing a hydrocyanic acid.
