The invention relates to a thermal process for the production of directly tablettable granules and pharmaceutical preparations produced therefrom.

Thermal granulation process

A carbon- and nitrogen-based catalyst consisting essentially of active carbon or active coke and comprising at least 90% by weight of graphite structures containing at least 10% of pores larger than 100 nm in diameter and having incorporated therein an isocyanate which forms C-N-ring structures, the percentage graphite content being at least 90% by weight. The catalayst is especially effective in the low temperature reduction of nitrogen oxides in waste gases.
