Abstract
The invention relates to a process for the catalytic hydrotreating of a feedstock of petroleum origin of diesel fuel type and of a feedstock of biological origin based on vegetable oils and/or animal fats in a stationary bed catalytic hydrotreating unit, the said process being characterized in that the feedstock of petroleum origin is introduced into the said reactor upstream of the feedstock of biological origin.It also relates to a catalytic hydrotreating unit for the implementation of the said process and to a corresponding hydrorefining unit.
