n.焦性沥青
The yields of gaseous hydrocarbon had the analogy change trend with the yields of pyrobitumen. 研究发现，原油和沥青质裂解气各组分及焦沥青的产率变化类似。
The pyrobitumen containing mostly clay mineral can be used as decolorizing and absorbing material of waste water and oil, or used as absorbent for lube-oil complementing and refining process. 以粘土矿物为主的热解残渣直接用作废水与油品脱色吸附材料或用作润滑油补充精制的吸附剂；
