METHOD FOR HYDROTREATING HEAVY HYDROCARBON FEEDSTOCKS USING PERMUTABLE REACTORS INCLUDING AT LEAST ONE STEP OF SHORT-CIRCUITING A CATALYST BED

摘要

The present invention relates to a method for hydrotreating heavy hydrocarbon fractions using a system of replaceable fixed bed guard zones, wherein each fixed bed guard region comprises at least two catalyst beds, wherein in the system, The raw material feed point is moved downstream as the catalyst bed initially placed in contact with the raw material is deactivated and sealed. The present invention also relates to a plant that performs this method.
