Abstract

The oxidation products of electrode pitch (category C) in a reactor with large gas capacity are considered. The influence of the oxidation time on the softening point and yield of volatiles in the production of high-temperature coal tar pitch is determined. In the experiments, the oxidation of electrode pitch is investigated as a function of the oxidation time and the maximum temperature. Oxidation occurs in the range 260–360°C. The air flow rate is 800 L/kg h. The yield of products, the softening point, and the yield of volatiles are determined as a function of the oxidation time. The increase in softening point may be attributed to the increase in oxidation time at temperatures above 300°C. The conditions for the production of high-temperature coal tar pitch by oxidation of electrode pitch are established. The dependence of the carbonizate yield on the oxidation time is determined.

大气容反应器中电极沥青的氧化产物
研究了C类电极沥青在大气容反应器中的氧化产物。测定了高温煤焦油沥青生产过程中氧化时间对软化点和挥发物收率的影响。在实验中,研究了电极沥青的氧化与氧化时间和最高温度的关系。氧化发生在260-360°C范围内。空气流速为800 L/kg h,产物得率、软化点、挥发物得率随氧化时间的变化而变化。软化点的增加可能是由于在300℃以上的温度下氧化时间的增加。确定了电极沥青氧化法制备高温煤焦油沥青的条件。测定了炭化产物产率与氧化时间的关系。
