Reducing the carcinogenic impact of pitch processing

Reducing the carcinogenic impact of pitch processing Diverse opinions exist regarding the properties of benz[a]pyrene and other polycyclic aromatic hydrocarbons in coal pitch and their carcinogenic impact. Current concepts regarding chemical carcinogenesis and the development of occupational sickness are outlined. Information is presented relating to the reduction in the carcinogenic impact of coal pitch and its processing products. It is shown that the content of benz[a]pyrene and other polycyclic aromatic hydrocarbons in coal pitch, its sublimates, and atmospheric emissions may be reduced by means of various additives. However, it is probably impossible to eliminate benz[a]pyrene emission completely, since it is an unavoidable product of the high-temperature pyrolysis of organic materials. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

Diverse opinions exist regarding the properties of benz[a]pyrene and other polycyclic aromatic hydrocarbons in coal pitch and their carcinogenic impact. Current concepts regarding chemical carcinogenesis and the development of occupational sickness are outlined. Information is presented relating to the reduction in the carcinogenic impact of coal pitch and its processing products. It is shown that the content of benz[a]pyrene and other polycyclic aromatic hydrocarbons in coal pitch, its sublimates, and atmospheric emissions may be reduced by means of various additives. However, it is probably impossible to eliminate benz[a]pyrene emission completely, since it is an unavoidable product of the high-temperature pyrolysis of organic materials.
