沥青焦沥青焦pitch coke liqlngj该。沥青焦(Pitchc砍e)煤焦油沥青经炭化后生成的固体产物。肠青焦质地坚硬，呈铁灰色，气孔较大(最大孔径可达5~以上)，孔壁较厚(l一4~)，壁上有大量的细裂纹和微孔。与普通焦炭相比沥青焦含碳高，灰及硫含量低，强度亦较好，多作为生产人造石墨、电解铝用阳极糊以及石墨电极等炭素制品的原料。 炼制沥青焦可在硅砖沥青燕护中进行，也可采用延迟焦化法。(见沥青延迟焦化)在焦炉中生产沥青焦时，入炉料可以是固体中温沥青，也可以是液体中温沥青或液体高温沥青(软化点为135一巧0℃)。由于在焦炉中炼制沥青焦时劳动条件很差，这种炼制沥青焦方法已逐渐为延迟焦化法所代替。 沥青在焦炉中炭化时经历了蒸发、热解和热缩合等变化，变化过程可分为四个温度区间:<300℃;300一45oaC;450一5500C和>550℃。其中最重要的温度区间为450~550℃，在此温度范围内轻组分蒸出、沥青基质分解并形成气态产物和重质产品。重质产品固化生成半焦。继续加热时(>550C)逸出富氢的挥发物，在焦炭基质中出现收缩裂纹。当焦饼中心温度达90。一1 oooc时，结束炼焦过程。成熟的沥青焦由炉室推出后用干熄或湿熄法冷却，之后送往筛焦楼。沥青炼焦过程中逸出的气态产物经冷却除掉煤焦油后进入焦炉煤气管道。所得沥青焦油，用空气处理使之转变为高温沥青，以便用于生产电极焦。炼焦产品的产率为:焦炭64~69%，煤焦油27~22%，热炉煤气8%。一些国家针对具体条件制订了本国的沥青焦质量标准，中国沥青焦质量标准见表。 中国沥青焦质量标准指标…灰:、…::…，发、…:国膨水:。电极冶炼用}簇0.5.镇0.5}镇1.2{1.96{镇4{簇3电碳制品用1簇。·“…簇。·5…镇1.2…工·“。}簇‘1毛5
