PROCESS FOR HYDROTREATING A DIESEL FUEL FEEDSTOCK WITH A FEEDSTOCK OF NATURAL OCCURRING OIL(S), HYDROTREATING UNIT FOR THE IMPLEMENTATION OF THE SAID PROCESS, AND CORRESPONDING HYDROREFINING UNIT

摘要

The invention relates a process for the catalytic hydrotreating of a feedstock of petroleum origin of diesel fuel type introduced into a stationary bed hydrotreating unit upstream of a feedstock of natural occurring oil(s) characterized in that the feedstock of natural occurring oil(s) contains acyl-containing compounds having 10 to 24 carbons including fatty acid esters and free fatty acids and said feedstock of natural occurring oil(s) is submitted to a refining by a hydrodynamic cavitation before its introduction into the stationary bed processing.
