A NEW PREPARATION METHOD OF CATALYST FOR AMMONIA-SYNTHESIS

The preparation of a new catalyst for ammonia synthesis on the basis o f a carbon support relies on a thoroughly mixing of polyacrylonitrile (PAN) with inorganic salts Fe(NO3)(3) and KNO3 being previously dissol ved in dimethylformamid (DMF). A catalyst was reduced at the flow of N -2-H-2 mixture before activity measurements. The preparation condition s, leading to the manufacture of catalyst showing higher activity at a tmospheric pressure than an industrial iron fused catalyst, were found . The optimal composition of precursor and the temperature carbonizati on were found.
