Process for hydrotreating a diesel fuel feedstock, hydrotreating unit for the implementation of the said process, and corresponding hydrorefining unit

摘要

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.

1. 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 hydrotreating unit, comprising the step of:
introducing the feedstock of petroleum origin into the hydrotreating unit upstream of the feedstock of biological origin such that a hydrodeoxygenation of the feedstock of biological origin takes place downstream of a hydrodesulfurization of the feedstock of petroleum origin, and the level of the feedstock of biological origin based on vegetable oils and/or animal fats is up to 30% by weight.
