将1%富钙碱渣配入焦煤中制备焦炭，采用自制小型垂直固定床反应器研究了900~1200℃下所得焦炭的溶损反应过程. 结果表明，碳素溶损率小于15%时焦炭的溶损反应速率基本不变，碳素溶损率大于15%时溶损反应速率逐渐减小. 焦炭反应后的比表面积随碳素溶损率增加先增大后减小，在溶损率约为15%时最大. 配入富钙碱渣提高了焦炭的溶损反应速率，增大了焦炭的反应性，溶损温度越高，溶损速率增幅越大. 用随机孔模型描述了焦炭的溶损反应动力学过程，基础焦炭和添加1%碱渣的焦炭的溶损反应表观活化能分别为132.15和103.81 kJ/mol.

Coke was prepared by coking of coal with addition of Ca-based slag as a catalyst. The solution loss reaction of coke at different temperatures (900~1200℃) was studied in a self-made vertical fixed-bed reactor. The results showed that the solution loss rate of coke remained constant when carbon loss rate (x) was less than 15%, and the solution loss rate gradually decreased at x>15%. The specific surface area of coke after reaction first increased and then decreased, and reached the maximum value at x"15%. Furthermore, the addition of slag improved the solution loss rate of coke, and enhanced its reactivity. A random pore model was used to describe the solution loss reaction of coke, and the activation energy of coke and coke with 1% slag was 132.15 and 103.81 kJ/mol, respectively.
