Petroleum & Coal Products Manufacturing(石油及煤制品制造业)
The Petroleum and Coal Products Manufacturing sector is based on the transformation of crude petroleum and coal into usable products. The dominant process is petroleum refining that involves the separation of crude petroleum into component products through such techniques as cracking and distillation. In addition, this sector includes establishments that primarily further process refined petroleum and coal products and produce products, such as asphalt coatings and petroleum lubricating oils. However, establishments that manufacture petrochemicals from refined petroleum are classified under Chemical Manufacturing.
