煅后焦微量元素与反应性的关系研究

Relationship between reactivity and the content of trace metals of calcined petroleum coke

对不同硫含量的石油焦进行煅烧处理,考察微量元素对煅后焦空气反应性和CO2反应性的影响。结果表明:硫可以抑制煅后焦CO2反应性,而微量元素钙和钠则增加煅后焦CO2反应性;钒与镍会提高煅后焦的空气反应性。

Influences of the trace metals in calcined petroleum coke on its reactivity were discussed in this paper. The results showed that CO2 reactivity has positive correlation with sodium and calcium in coke, but negative correlation with sulfur, while air reactivity increases with the increase of the vanadium and nickel contents.
