石油沥青烟气组成及抑烟技术研究进展.

The toxic components and odorous components in the fumes of petroleum asphalt are introduced in detail, and some suggestions for the establishment of the standard and specification of the toxic components and odorous components in the fumes of petroleum asphalt are put forward・ The toxic components in petroleum asphalt smoke are mainly 2 〜6 rings of polycyclic aromatic hydrocarbons (PAHs), including benzo [a] anthracene, benzo [a] pyrene and benzo [e] pyrene, which have been shown to be carcinogenic to human body and toxic to nervous system・ The odor group of petroleum asphalt flue gas is divided into sulfur and nitrogen compounds, including thiophene similar substance and sulfoxide, and also contains a small amount of indole nitrogen odor pollutants・ The research status of adsorption type fumes suppressor, oxidation type fumes suppressor and polymer fumes suppressor in petroleum asphalt suppression technology is introduced and evaluated・ In add让ion, the research expectation of petroleum asphalt fumes suppressor is predicted.
