ABSTRACT:
A multistage hydrocracking or hydrotreating process wherein a two-phase reaction mixture of a hydrogen rich gas stream and liquid hydrocarbon is passed through a series of spaced catalyst beds and reaction vapors are withdrawn at each interspace between beds and replaced with hydrogen. Such withdrawal and replacement reduces the partial pressure of NH.sub.3 and/or H.sub.2 S in the reaction mixture entering the bed succeeding each interspace, thereby increasing the reaction rate between hydrogen and the liquid hydrocarbon.
