ABSTRACT:
The present invention relates to a process for heteroatom removal, particularly during process excursions, from petroleum and chemical hydrocarbon streams. The invention is comprised of at least two zones through which the hydrocarbon stream and a hydrogen containing treat gas flow. The first zone contains a bed of heteroatom hydroprocessing catalyst in contact with hydrogen-containing treat gas and the second zone contains heteroatom sorbent material(s) through which the hydrocarbon stream flows countercurrent to the up flowing hydrogen-containing treat gas.
