Filtration tray for catalytic chemical reactor

A particle separation system for a catalytic chemical reactor, wherein the particle separation system comprises a plurality of filtration sections comprising overfill systems, thereby enabling particle capture while keeping the pressure drop over the separation system constant and limiting the liquid load across the system, wherein the particle separation system comprises at least one filtration tray comprising a number of basins with basin walls for collection of liquid, thereby combining sedimentation and filtration.
