GAS AND LIQUID PHASE HYDROPROCESSING FOR BIOCOMPONENT FEEDSTOCKS

摘要

Diesel fuel is produced from a feedstock that is at least partially biocomponent in origin. A feedstock is treated in a reactor including one or more hydrotreating zones having a continuous gas phase. The liquid effluent from the hydrotreating zones is then hydroprocessed in a hydroprocessing zone having a continuous liquid phase, such as a hydroprocessmg zone in the same reactor. The hydroprocessing zone can be operated under effective catalytic dewaxing conditions.
