The invention relates to a process for the catalytic hydrotreating of a feed of oil origin, of diesel fuel type, in at least one fixed-bed hydrotreating reactor, for manufacturing diesel fuel, characterized in that incorporated into said feed are vegetable oils and/or animal fats up to a level of around 30% by weight, the mixture of said feed and vegetable oils and/or animal fats being introduced into the reactor operating in a single pass, without recycling liquid effluent at the top of the reactor. It also relates to a hydrotreating reactor for implementing said process, and to a corresponding hydrorefining unit.

Process for the hydrotreatment of a gas-oil feedstock, reactor for implementing said process, and corresponding hydrorefining unit

The invention relates to a process for hydrodeoxygenation (HDO) of pyrolysis oil and also to a process for upgrading of pyrolysis oil implementing said HDO process, and also to processing of the aqueous phase resulting from the HDO by steam pre-reforming and then steam reforming.

Process for hydrodeoxygenation and process for upgrading of pyrolysis oil resulting from biomass, which are capable of operating continuously

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.

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