一、原理 氮跟氢是极不容易化合的。为了加快氮跟氢的合成反应速度,都采用以铁为主体的多成分催化剂——铁触媒。根据催化剂能够同样地加快正反应和逆反应的速度,铁触媒必然能加速氨的分解。 千卡又因为合成氨反应是放热的,因此当压强一定,温度升高时,化学平衡会向生成氮和氢的方向移动。 First, the principle Nitrogen is very difficult to combine with hydrogen. In order to speed up the synthesis of nitrogen and hydrogen, iron-based multi-component catalysts are used as iron catalysts. According to the catalyst, the speed of the positive reaction and the reverse reaction can be accelerated, and the iron catalyst can accelerate the decomposition of ammonia. The kilocalorie is also exothermic due to the reaction of synthetic ammonia, so when the pressure is constant and the temperature rises, the chemical equilibrium moves toward the generation of nitrogen and hydrogen.
