The phenol-degrading strain Trichosporon cutaneum R57 utilizes various aromatic and aliphatic compounds as a sole carbon and energy source. The intracellular activities of phenol hydroxylase [EC 1.14.13.7] of a Trichosporon cutaneum R57 strain grown on phenol (0.5 g/l) were measured. Different toxic phenol derivatives (cresols, nitrophenols and hydroxyphenols) were used as substrates in the rea...

A review of the current literature shows there is no clear consensus regarding reaction mechanisms air-borne aromatic compounds such as toluene by photocatalytic oxidation. Potential oxidation reactions over TiO2 or TiO2-based catalysts under ultraviolet and visible (UV/VIS) illumination are most commonly considered for removal these pollutants. Along pathways from a model pollutant, toluene, t...

Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature. It is a black, viscous liquid composed primarily of a complex mixture of condensed-ring aromatic hydrocarbons. It may contain phenolic compounds, aromatic nitrogen bases and their alkyl derivatives, and paraffinic and olefinic hydrocarbons. Coal-tar pitch is t...

The remarkable enhancement of phenolic monomer generation and hydrogen was achieved through catalytic pyrolysis Douglas fir over nanocellulose derived biochar catalyst for the first time. main compositions produced bio-oil were monomers, furans, naphthalenes, etc., in which monomers dominant compositions. And at temperature 650 °C 3 to biomass ratio, quantification results showed that concentra...
