摘要:

从密度、气孔率、反应性和微观结构等方面对捣固焦和顶装焦进行对比分析可知,捣固焦具有较高的显密度和显气孔率;碱金属对焦炭溶损反应起催化作用,碱金属对捣固焦的催化作用大于顶装焦。

Abstract:

It analyzes density,porosity,reactivity and micro-structure etc.of stamp-charged coke and top-charged coke,concluding stamp-charged coke is of high apparent porosity and density.Alkali metal functions as catalyst in coke loss reaction and it is more catalytic for stamp-charged coke than for top-charged coke.
