| 摘要 |
The invention relates to a process for continuously preparing hydrogen cyanide by reacting ammonia with hydrocarbons, the reaction gas mixture being brought to reaction temperature in the fluidized bed by means of indirect heating by contact with a particulate heat transferrer, and which is characterized in that the heat transferrer is conducted cyclically in a transported fluidized bed, the heat transferrer being heated in an ascending transport stream and being contacted with the reaction gas mixture in a descending transport stream. |
