Abstract:
1. A reactor system effective for dehydrogenation of an alkyl aromatic compound to a corresponding vinyl aromatic compound comprising: a) a vertically oriented radial flow reactor comprising an inner reactor tube having a perforated wall and an outer reactor tube having a perforated wall extending longitudinally of said reactor and defining an annulus in which a porous longitudinally extending catalyst bed is located; b) a supply line extending into an inlet of said radial flow reactor at one end thereof; c) an injection nozzle extending into said supply line, said injection nozzle comprising a concurrent flow tube defined by an interior chamber and an outer chamber extending concurrently with said interior chamber; and d) a rotation vane disposed within said supply line adapted to impart a spiral flow component to a fluid flowing through said supply line and wherein said injection nozzle extends into said supply line at a location spaced downstream from said rotation vane; wherein no rotation vane is positioned downstream of said injection nozzle.
