PROCESS FOR THE ΗYDROCONVERSION OF HEAVY FEEDSTOCKS IN AN EBULLATED BED WITH INJECTION OF FEEDSTOCK AT THE TOP OF THE REACTOR

摘要

The invention relates to a process for the hydroconversion, in an ebullated bed, of a petroleum feedstock containing a significant amount of light fractions and, inter alia, asphaltenes, sulphur-containing and metallic impurities. More precisely, the subject of the invention is a hydroconversion process that uses at least one ebullated-bed reactor for which the injection of the feedstock is carried out at the top of said reactor, in the overhead and that includes a separation within said feedstock inside the reactor into a vaporized fraction and a liquid fraction. The invention also relates to the reactor that makes it possible to carry out said process.
