摘要
A method, and a reactor, for hydroprocessing a hydrocarbon feed stream through multistage moving catalyst beds contained within a single onstream reactor vessel, with separate catalyst addition and withdrawal systems for each of the multistages of moving catalyst beds. The reactor contains two or more different and distinct moving catalyst beds for any hydroprocessing application. The method includes serially passing, without leaving the reactor vessel, at least a partially treated hydrocarbon stream from one hydroconversion reaction zone containing a moving catalyst bed with a first set of catalytic characteristics to another hydroconversion reaction zone containing a moving catalyst bed with a second set of catalytic characteristics that differ in catalytic abilities from the first set of catalytic characteristics.
