含氮杂环化合物的加氢脱氮是通过芳环、杂环的加氢饱和,接着碳—氮键断裂而进行的.对加氢脱氮催化剂的改进需要照顾到环加氢及碳—氮键断裂之间的平衡.如果发生过多的环的饱和,将引起大量氢气消耗;但如果没有部分的环加氢饱和,则联—氮键的断裂将是很困难的.研究催化剂的脱氮作用需要对环的加氢及碳—氮键断裂的相对速度进行测定,以便比较各反应步骤的相对反应动力学的速度常数.对Co-Mo,Ni-Mo 催化 The hydrodenitrogenation of nitrogen-containing heterocyclic compounds is carried out by hydrogenation of the aromatic rings, heterocyclic rings, followed by carbon-nitrogen bond cleavage.The improvement of the hydrodenitrogenation catalyst takes care of the ring hydrogenation and the carbon-nitrogen If the ring saturation is too large, it will cause a lot of hydrogen consumption, but if there is no part of the ring saturated with hydrogen, then the linkage - nitrogen bond fracture will be very difficult to study the catalyst of nitrogen The effect of the ring hydrogenation and the carbon-nitrogen bond rupture relative velocity was measured in order to compare the relative reaction kinetic velocity constants of each reaction step.For the catalytic Co-Mo, Ni-Mo catalyst
