焦炭反应性的多元素矿物催化研究

Research of Multi-element Mineral Catalysis for Coke Reactivity

对F、S及单一矿物质或多种矿物质按不同比例混合时对焦炭反应性的影响进行了研究。结果表明:碱土金属氧化物BaO、CaO、MgO和过渡金属氧化物Fe2O3、CuO、V2O5及硫的氧化物SO3对焦炭的反应性起正催化作用,但Fe2O3、CuO、V2O5和MgO的催化作用随添加量的增加有一个饱和点;B2O3、TiO2和AlF3对焦炭反应性有负催化作用。几种氧化物混合后对焦炭反应性的影响表现出单一物质作用的加和性。

The influence of F, S, single mineral and multi-mineral mixture on coke reactivity was studied. The result shows that alkaline earth oxides such as BaO, CaO, MgO and transition metal oxides such as Fe2O3, CuO, V2O5 and sulfur oxides such as SO3 have positive catalytic effect on coke reactivity, but there is a saturation point for Fe2O3, CuO, V2O5 and MgO·B2O3, TiO2 and AIF3 have negative effect. In addition, the effect of mixture of several oxides on coke reactivity shows additive property for single substance.
