补充资料：石油焦
| 石油焦 petroleum coke 渣油经延迟焦化而制得的一种焦炭。其本质是一种部分石墨化的碳素形态。多孔，呈堆积颗粒状，不能熔融。元素组成主要为碳，间或含有少量的氢、氮、硫、氧和某些金属元素，有时还带有水分。广泛用于冶金、化工等工业作为电极或生产化工产品的原料。石油焦的质量很大程度上取决于原料的性质及其加工条件。主要质量指标有纯度、结晶度、抗热震性、颗粒度。纯度是指石油焦中硫及灰分等的含量。结晶度是指焦炭的结构和中间相小球体的大小。抗热震性是指焦炭制品在承受突然升至高温或从高温急剧冷却的热冲击时的抗破裂性能。颗粒度反映焦炭中所含粉末焦和块状颗粒焦（可用焦）的相对含量。 |
