The effects of the dosage of active components, reaction temperature and gas hourly space velocity on catalyst activity and selectivity were surveyed. 评价了活性组分的添加量、操作温度和空速对催化剂活性和选择性的影响。
However, although the reported catalytic systems gave high N2 conversion, the gas hourly space velocity ( GHSV) employed in the reactions was far lower than that required by practical application. 然而,虽然这些催化体系能够给出高的N2转化率,但其所适宜的空速(GHSV)却远远低于实际应用的要求。
