Zusammenfassung:	An improved grid plate flow distributor assembly for use in a pressurized catalytic reactor in which gas and liquid materials flow uniformly upwardly through the grid into the reactor ebullated catalyst bed. The grid plate assembly contains multiple vertical flow tubes each covered at its upper end by a cap which is spaced outwardly from the tube upper end and preferably has tapered sides. The cap can have any horizontal cross-sectional shape, such as circular, polygonal, rectangular or triangular. If desired, a horizontal elongated cap can be used which covers at least two adjacent vertical flow tubes. Such elongated caps can be provided as concentric circular shapes above the grid plate. Also, if desired, a thermocouple can be provided extending upwardly above the cap, such as through selected caps to monitor the temperature distribution of the ebullated bed above the grid plate assembly.
