Abstract:
A reformer includes a reforming chamber having a raw fuel passage through which a raw fuel flows, the reforming chamber being filled with or carrying a reforming catalyst, a supply chamber disposed upstream of the reforming chamber, for uniformly supplying the raw fuel to the raw fuel passage, and a discharge chamber disposed downstream of the reforming chamber, for uniformly discharging the raw fuel from the raw fuel passage. The raw fuel passage has first and second reversers for reversing the direction in which the raw fuel flows. The raw fuel passage has a cross-sectional area which is smaller in a downstream portion thereof than in an upstream portion thereof.

Abstract:
A downcomer having a screened or otherwise liquid permeable wall is provided for use in a mass transfer or distillation column. The liquid permeable wall provides another avenue for liquid to be removed from the downcomer to increase the liquid handling capacity of the downcomer. When wetted, the liquid permeable wall provides a barrier against vapor entry into the downcomer through the wall.
Abstract:
A column having a region for reaction with distillation of fluid streams is provided with structures including catalyst-filled containers having liquid permeable upper surfaces which allow for the accumulation and flow of liquid from a liquid stream. The containers include catalyst beds positioned beneath the upper surface of the containers. A portion of the liquid on the containers is driven through the catalyst bed by the liquid head created by the accumulated liquid and is catalytically reacted. Another portion of the liquid may be directed through a downcomer which allows the accumulated liquid to leave the container without passing through the catalyst bed so that higher volumetric flow rates can be achieved.
Abstract:
A reaction with distillation column is provided with a plurality of discrete catalytic reaction containers. The containers contain a plurality of solid catalyst particles which form a catalytic reaction zone. The containers also comprise a liquid collection tray cover which defines a liquid accumulation zone immediately overlying the catalytic reaction zone. Overflow weirs are provided on the tray cover to allow for overflow of liquid on the tray cover. A member may be provided within the containers to create an open area within the catalytic reaction zone to facilitate entry of the liquid into the catalytic reaction zone. The containers can be individually positioned within the reactor to suit particular process requirements.
Abstract:
A REACTOR VESSEL HAVING AN OUTER SHELL, A HEAT EXCHANGER AND AN INNER SHELL, THE INNER SHELL CONTAINING A SERIES OF CATALYTIC REACTION BEDS HAVING THEIR ENTRANCE AREAS DISPOSED PARALLEL TO THE LONGITUDINAL AXIS OF THE OUTER AND INNER SHELLS.
