Claim:
A liquid recycle inlet stream distributor assembly for introducing a liquid recycle stream through a bottom of a reactor vessel and also mixing the liquid recycle stream with a primary feedstream introduced into the reactor vessel above the distributor assembly by a feedstream inlet sparger, the inlet stream distributor assembly comprising: an inlet conduit connected to a liquid recycle stream conduit and disposed through a bottom of a reactor vessel for introducing a liquid recycle stream from the liquid recycle stream conduit through the bottom of the reactor vessel; an open plate or ring attached to or disposed above said inlet conduit and including a substantially flat body bounded by an exterior edge and an interior edge, and an interior opening therethrough bounded by said interior edge, a closed plate disposed above said plate or ring for diverting the liquid recycle stream from said inlet conduit laterally into the reactor vessel through exit openings above and below said plate or ring; and curved fins laterally disposed on upper and lower sides of said open plate or ring at spaced apart intervals so as to at least partially redirect flow of the liquid recycle stream through said exit openings.
