  • Hydrotreating of pyrolysis gasoline
    Patent number: 4097370
    Abstract: In the hydrotreating of pyrolysis gasoline, recycle effluent is treated to separate the more volatile components therefrom, prior to recycle, to thereby increase the hydrogen partial pressure of the hydrotreating. In this manner, total pressures can be reduced to correspond to the pressure of the available hydrogen gas, while retaining the kinetic benefits of increased partial pressures.
