The effect of size of crystallites on the nitriding process of the fused iron catalyst
Promoted nanocrystal. Fe of varying size of crystallites was nitrided with NH(3) in a differential reactor under atm. pressure at 475 degrees C. Thermogravimetric measurements, anal. of the gas phase compn. were carried out simultaneously. With an increase of the crystallite sizes, the nitriding degree of analyzed samples increased, but the rate of catalytic NH(3) decompn. on the Fe surface decreased.
