Solid catalyst liquid phase hydroprocessing using moving bed reactors

A process for hydroprocessing comprising:

• providing at least two moving bed reactors, the moving bed reactors including:
• a first moving bed reactor including a first reaction zone containing catalyst;
• and
• a second moving bed reactor including a second reaction zone containing catalyst;
• transferring catalyst, periodically or continuously, from the first reaction zone of the first moving bed reactor to the second reaction zone of the second moving bed reactor;
• passing a liquid feed stream comprising a hydrocarbonaceous feed stream and hydrogen to the first reactor, wherein the liquid feed stream undergoes a hydroprocessing reaction in the first reaction zone to produce a first reactor effluent stream, and first reactor effluent stream is removed from an outlet of the first reactor;
• passing the first reactor effluent stream though one or more unit operations wherein the pressure of the first reaction zone effluent stream at the first unit operation is lower than the pressure of the first reactant effluent stream at the outlet of the first reaction zone, and the pressure at the inlet of all subsequent unit operations is lower than the prior upstream operation, to generate a liquid phase or substantially liquid phase stream;
• passing the liquid phase or substantially liquid phase stream to the second reaction zone, the liquid phase stream having a pressure at the second reaction zone inlet that is lower than a pressure of the liquid phase or substantially liquid phase stream at the inlet of the last unit operation, wherein the liquid phase or substantially liquid phase stream undergoes hydroprocessing to generate a second reactor effluent stream;
• and
• passing the second reactor stream from the second or a final reaction zone to a product recovery zone.
