A reactor and feed distribution assembly comprising: a reactor vessel having a refractory-lined inner wall surface, an outer wall surface, a bottom, a top, a gaseous feed distribution assembly, and a mounting plate, wherein: the bottom has an inner surface and an outer surface,the gaseous feed distribution assembly has a first surface that faces the inner surface, a second surface that is spaced apart from and faces away from the first surface, and an outer plate surface having a portion that is normal to the first surface and the second surface, wherein the gaseous feed distribution assembly defines a plurality of gas passageways, each of the plurality of gas passageways being in fluid communication with the first surface and the second surface via first apertures and second apertures, the second apertures having a greater cross-sectional area than the first apertures, and wherein distribution assembly insulation packing is disposed between a lower portion of refractory-lined inner wall surface that is nearer to where the refractory-lined inner wall surface connects to the bottom than to where the refractory-lined inner wall surface connects to the top,the mounting plate having a first end, which is operatively connected to the bottom, and a second end, wherein the first end and the second end are spaced apart from one another and there between define an outer planar surface that is spaced apart from an inner planar surface, the outer planar surface being spaced apart from the refractory-lined inner wall surface, the outer plate surface being operatively connected to a portion of the inner planar surface proximate to the second end and apart from the first end,a gaseous feed conduit that is operatively connected to a gaseous feed conduit receiving passageway that extends through the bottom of the reactor vessel;a catalyst feed conduit that has a first end and a second end, the catalyst feed conduit extending through the refractory-lined inner wall surface and the outer wall surface such that the second end is positioned above the second surface of the gaseous feed distribution assembly;a catalyst feed conduit receiving passageway; anda catalyst feed conduit housing in which the catalyst feed conduit is slidably housed, the catalyst feed conduit being spaced apart from an inner surface of the catalyst feed conduit housing, the catalyst feed conduit housing having a first end proximate to the bottom of the reactor vessel, a second end spaced apart from the bottom of the reactor vessel and proximate to the second surface of the gaseous feed distribution assembly, and an outer surface that is spaced apart from the inner surface of the catalyst feed conduit housing and operatively connected to an inner circumferential surface of a catalyst feed conduit passageway and to the catalyst feed conduit receiving passageway, wherein catalyst feed conduit insulation is disposed between the catalyst feed conduit and the inner surface of the catalyst feed conduit housing. 2. The reactor and feed distribution assembly of claim 1, further comprising a plurality of gaseous feed conduits. 3. The reactor and feed distribution assembly of claim 1, further comprising a plurality of catalyst feed conduits. 4. The reactor and feed distribution assembly of claim 1, wherein a ratio of an inside diameter of the first apertures of the gaseous feed distribution assembly to an inside diameter of the second apertures of the gaseous feed distribution assembly is from 0.13 to 0.63. 5. The reactor and feed distribution assembly of claim 1, wherein a ratio of the inside diameter of the first apertures of the gaseous feed distribution assembly to an inside diameter of the reactor vessel is from 0.003 to 0.014. 6. The reactor and feed distribution assembly of claim 1, wherein a ratio of the inside diameter of the second apertures of the gaseous feed distribution assembly to the inside diameter of the reactor vessel is from 0.008 to 0.163. 7. The reactor and feed distribution assembly of claim 1, wherein a ratio of an inside diameter of the gaseous feed conduit to the inside diameter of the reactor vessel is from 0.06 to 0.77. 8. The reactor and feed distribution assembly of claim 1, wherein a ratio of an inside diameter of the catalyst feed conduit to the inside diameter of the reactor vessel is from 0.08 to 0.23. 9. The reactor and feed distribution assembly of claim 1, further comprising a deflector plate spaced apart from, and operatively connected to, a portion of the first surface of the gaseous feed distribution assembly by way of a plurality of deflector plate connectors. 10. The reactor and feed distribution assembly of claim 1, further comprising: a catalyst backflow diverter that is operatively connected to the catalyst feed conduit proximate to the second end of the catalyst feed conduit, the catalyst backflow diverter extending from the catalyst feed conduit and extending beyond the second end of the catalyst feed conduit housing.
