本文报导了最近试制的一种高分子钼铁硫络合物固氮催化剂的研究成果。这种催化剂对乙炔加氫还原成乙烯反应的初速度是1.3摩尔/摩尔·分。与同类型固载化催化剂——葡聚糖凝胶一半胱氨酸钼络合物的初速度相近。实验表明,在催化反应过程中,它的活性组分不易脱落,循环使用时仍有较高的活性。初步测定了催化剂组成与活性之间的关系,它与固氮酶活性组分的元素组成是一致的。这些实验结果,对于在理论上进一步研究生物固氮机理和在工业生产上寻找一个适用的固氮催化剂,都是颇有裨益的。
This paper reports the recent trial production of a polymer ferromolybdenum sulfur complex nitrogen fixation catalyst research results. The initial velocity of this catalyst for the hydrogen reduction of acetylene to ethylene was 1.3 moles per mole fraction. With the same type of immobilized catalyst - Sephadex-cystine molybdenum complex initial velocity similar. Experiments show that in the catalytic reaction process, its active ingredient is not easy to fall off, still have a higher activity when recycled. The preliminary determination of the relationship between the catalyst composition and activity, which is consistent with the elemental composition of the nitrogenase active component. These experimental results are of great benefit to further study the biological nitrogen fixation mechanism in theory and find a suitable nitrogen fixation catalyst in industrial production.
