FIELD: chemistry.
SUBSTANCE: invention can be applied in chemical industry. In order to carry out continuous synthesis of hydrogen cyanide by reaction of ammonia with hydrocarbons, reaction gas mixture is brought to temperature of reaction by indirect heating by contact with heat carrier in form of particles in fluidised bed. Circulation of heat carrier in transport fluidised bed is ensured. Heating of heat carrier is carried out in rising transport flow, and contact of heat carrier with reaction gas mixture is ensured in descending transport flow.
EFFECT: invention makes it possible to increase output of product with simplification of process.
