## Abstract The main objective of present study was to assess the evaporation profile of monoaromatic compounds, namely, benzene, toluene, and xylenes (BTX) from gasoline–ethanol‐blend fuels. The vapors from two river sand columns contaminated with gasoline and gasoline–ethanol were monitored for 7
Vapor grown carbon fibers were successfully produced from benzene, toluene and xylene, and also from mixtures of these hydrocarbons using the liquid pulse injection technique developed by the authors. This indicates the possibility of the usage of this kind of low-cost material as the carbon source
