Abstract
A distributor nozzle for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device includes a number of fixing bars and a deflector cone frustum. The deflector cones or cone frusta may have more than one angle in order to improve the distribution, and they have a number of apertures or slits and a number of vertical directing elements or a directing cage or frame to direct the stream of the two-phase charge in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the entire area of the bed in the reactor.
