A pressure vessel base closure means including a pair of flat disc-like members spaced apart by a peripheral outer cylindrical member and an inner perforated cylindrical member, and there being provided between the two flat disc-like members a plurality of radially directed ribs to provide rigidity to the base closure means. The base closure means is particularly useful for a reactor in which a bed of fluidized solid is maintained by the passage of a gas into the reactor through the base via the chamber between the two flat disc-like members.

Closure means

A supported vessel having a number of outwardly directed projections on the side of the vessel which are fixed to the outer end of horizontally disposed webs, the inner end of the webs being supported on a supporting structure, the lower end of which is secured in the ground, the weight of the vessel being transmitted to the webs through the support structure. The invention also claims a support for such a supported vessel.

Supported vessel and means for support thereof

A gas distributor tube formed from a non-porous ceramic material having a generally axial passageway at least part of which is in the form of a helix. A treatment chamber or reactor is provided with a number of distributor tubes located in the base of the chamber to permit the introduction of a gas through the passageway of this distributor into the treatment chamber in which a solid material in finely divided form may be maintained in fluid suspension.
