Summary:

The urea based SCR technology will face problems with the high freezing point (-11°C) of the reductant. In many parts of the world temperatures regularly fall much lower than this. With ammonium formate-urea solution the freezing point can be as low as - 30 °C.The reduction capacity of various ammonium formate solutions and its mixtures with urea were studied. When using ammonium formate and its mixtures as reductant in SCR experiments a significant improvement in the DeNOx activity in the low temperature operation was seen. In general in the engine experiments the ammonium formate-urea mixtures showed a reduction capacity comparable to standard urea
