摘要： The present invention provides a process for the production of guanidine nitrate by the reaction of urea and excess ammonium nitrate in the presence of a silicon dioxide catalyst at an elevated temperature, wherein the molten reaction mixture containing the dispersed catalyst is passed in a cycle, a branch current of the reaction mixture is continuously separated off by filtration in such a manner that the catalyst remains in circulation and consumed urea and ammonium nitrate are supplemented corresponding to the removal of the product.

摘要： Apparatus for removal of deleterious gaseous components from a flue gas, the flue gas is cooled, optionally subjected to preliminary purification, and optionally depleted of SO.sub.2. It is then heated in at least one heat exchanger and is passed over a catalyst suitable for the conversion of nitrogen oxides, whereupon the purified hot flue gas is conducted over at least one further heat exchanger and is discharged in the cooled state. Ammonia is preferably added to the heated flue gas.
