为了减少内燃机排气中的总碳氢和炭黑,我们探讨了用二苯甲蘸-β-二酮二茂铁的锰、锌,钴、镍、铜等五种络合物,为苯、环己烷、正己烷、含铅汽油(70~#)等代表性烃类的催化助燃添加剂,在其重量浓密为0.117％时,以氧弹热量计进行了评价。得出二苯甲酰-β-二酮二茂铁的锰,锌,钴的络合物有较好的催化助燃作用。这些络合物在含氧量为35—55％时,总碳氢为2—790ppm时,可使总碳氢下降22.6—90％;燃烧热上升0.3—9.4％。当氧弹燃烧室中,含氧量为45％时,炭黑含量为22—217mg时,这些络合物可使炭黑量下降5.2—57.6％。
In order to reduce the total hydrocarbon and carbon black in the exhaust of the internal combustion engine, five complexes of manganese, zinc, cobalt, nickel and copper with diphenyl-dip-β-diketoferrocene were explored for benzene, Cyclohexane, n-hexane, and leaded petrol (70 ~ #) were used as catalyst combustion-supporting additives. When their weight concentration was 0.117%, they were evaluated by the oxygen bomb calorimeter. It is concluded that the complexes of manganese, zinc and cobalt of dibenzoyl-β-diketoferrocene have better catalytic combustion-promoting effect. When the total oxygen content is 35-55%, these compounds can reduce the total hydrocarbon content by 22.6-90% and the combustion heat increase by 0.3-9.4% when the total hydrocarbon content is 2-790ppm. When the oxygen bomb combustion chamber, the oxygen content of 45%, the carbon black content of 22-217mg, these complexes can make carbon black volume decreased 5.2-57.6%.
