Activated carbons present very low thermal conductivity (0.2 W m −1 K −1 ) responsible for severe thermal limitations inducing low overall adsorption and desorption kinetics as well as secondary reaction products or hazards in industrial applicat

The present study was focused on the modelling of experimental pitches evolution data obtained under non-isothermal heat treatment. The model, previously proposed for isothermal heat treatment, was based on phenomenological basic mechanisms as gas–

The present study was focussed on the modelling of the evolution under heat treatment of the so-called γ, β and α-resins fractions usually used for pitches composition characterization. The model was based on phenomenologic basic mechanisms such a

Activated carbons with degrees of burn-off ranging from 12 wt.% to 60 wt.% have been prepared from toluene-insoluble (T.I.) fractions of a heat-treated A240 petroleum pitch. After toluene fractionation, the resulting pitches have been stabilized, car

Several amorphous carbonitride films have been elaborated by plasma enhanced chemical vapor deposition. A radio frequency discharge has been used under standard conditions with different graphitic nitrogenated compounds. It is shown that the influenc

Alpha relaxation and viscosity measurements performed above the glass transition region have been used for raw pitch molecular scale characterization. The characteristic time τ α of the alpha relaxation is known to be similar to the molecular mobil

The alpha-relaxation of a coal tar pitch has been experimentally illustrated through typical G′ and G″ isotherms steps and tan (δ) peak isochrone. This phenomena has been identified by means of its non-Debye (m ~ 1, n ~ 0.5) and non-Arrhenius be

Oscillatory measurements under controlled stress and controlled strain have been performed on the Ashland A240 isotropic petroleum pitch using a cone/plate rheometer. The storage and loss components of the modulus of rigidity have been analysed by me

Petroleum and coal tar pitches have been treated thermally at 400°C and 470°C, extracted with toluene and subsequently activated with CO2 at 900°C. With one exception, the development of the micropore widths and volumes in the resulting carbons fo
