在回转窑煅烧石油焦的过程中，大量的高温烟气和比较严重的粉尘是污染环境的主要因素。

There will be a lot of high-temperature smoke and serous power pollution in the production of petroleum coke calcined by rotary oven.

将武钢中温沥青和太钢高温沥青在不同压力下炭化，进一步对所得沥青焦进行了高温热处理；

Pitch cokes were prepared by carbonization of pitches from Wuhan Iron and Steel Plant and the Taiyuan Iron and Steel Plant under different pressures and heat treatments.

在高温下灰份的熔融是制焦温度影响煤焦气化速率的最重要原因之一。

Hence the catalytic action of mineral decreased, which may be the important reason that char gasification activity decreased with increasing making-char temperature.
