Abstract: A specific form of surface coating of Al2O3 catalysts, using additional amounts of aluminium ions and minimum amounts of platinum ions, made it possible to use Al2O3 as a catalyst for long-term operation (150 days and more) in the preparation of hydrogen cyanide from hydrocarbons and ammonia, preferably in the BMA process.
