C10C WORKING-UP PITCH, ASPHALT, BITUMEN, TAR; PYROLIGNEOUS ACID (compositions of bituminous materials C08L95/00; carbon filaments by decomposition of organic filaments D01F9/14)
Introduced: September 1968
Description
C10C covers industrial processes for refining and processing tar, pitch, asphalt, and bitumen derived from petroleum, coal, or wood, as well as the treatment of pyroligneous acid (wood vinegar). This includes distillation, separation, purification, and chemical modification of these materials to produce commercially useful products such as binders, adhesives, or specialty chemicals. The subclass encompasses both thermal and chemical processing methods applied to these coal tar and petroleum residues. Closely related processes for producing these raw materials from coal tar distillation or petroleum refining are classified elsewhere within C10.
