Abstract:
1. A process for introducing a first gas and a second gas into a reaction chamber of a reactor, the reactor comprising at least one reaction chamber wall and a gas distribution unit for distributing the first gas and the second gas into the reaction chamber, the distribution unit comprising a distributor having a plurality of distribution openings including at least one peripheral opening and at least one central opening, each of the distribution openings having a channel portion and a throttle portion, the distribution unit further comprising an inlet block, an outer annular ring, an inner annular ring concentric to the outer annular ring, a product withdrawal tube concentric to the outer annular ring and inner annular ring and that extends through the distributor and inlet block, the space between the distributor, inlet block, outer annular ring and inner annular ring defining a first gas plenum, the space between the distributor, inlet block, inner annular ring and the product withdrawal tube defining a second gas plenum, the process comprising: introducing the first gas into the first gas plenum and through the peripheral openings into the reaction chamber, the first gas passing through the channel portion at an angle with a longitudinal axis of the reaction chamber and through throttle portion of the distribution openings in a direction that is parallel with the longitudinal axis of the reaction chamber; and introducing the second gas through the second gas plenum and through the central openings into the reaction chamber, the second gas passing through the channel portion and throttle portion of the distribution openings.
