郑州大学化学系催化组研制的球形氨合成催化剂A_6C型和HAC型,近几年来先后在全国几十个大小化肥厂使用。结果表明催化剂的性能良好、增产效果明显。为此,国家决定在全国推广这一新产品。因此有必要对其物理化学性能进行全面的测定。我们曾先后测定了总表面、铁表面、碱表面,各种密度,比孔容和孔隙率等。由于孔的大小不仅决定了表面积的大
Zhengzhou University Department of Chemistry catalytic group developed spherical ammonia synthesis catalyst A_6C type and HAC type, in recent years has in the country dozens of fertilizer plant use. The results show that the performance of the catalyst is good, and the stimulation effect is obvious. To this end, the state decided to promote this new product throughout the country. Therefore, it is necessary to conduct a comprehensive determination of its physical and chemical properties. We have determined total surface, iron surface, alkali surface, various density, specific pore volume and porosity. Due to the size of the hole not only determines the surface area of the large
