Apparatus for the low pressure reforming of gasolines with heating by smoke gases

Claim 1

A reactor comprising at least one means for introducing a charge, at least one means for removing the processed charge, at least one means for introducing a powdery solid in the upper part of said reactor, at least one means for removing said solid from the lower part of said reactor, said reactor further comprising: at least two elementary reaction cells spaced apart from each other and spaced apart from the walls of said reactor, substantially vertical and parallelepipedic and substantially parallel to each other, at least two of said elementary reaction cells next to each other defining a substantially parallelepipedic channel; and at least one of said walls together with an elementary cell closest to said wall and substantially parallel to said wall defining a substantially parallelepipedic channel; said channels being suitable for gas flow, each of said cells being formed of the three following substantially parallelepipedic enclosures: an individual charge distributor, an individual processed charge collector, a powdery solid bed inserted between said individual distributor and said individual collector, said bed being open, over the whole of a substantially vertical first face, of said individual distributor and open, over the whole of the first face of said individual collector, said first faces each being defined by a wall permeable to fluids and impermeable to solid particles, said powdery solid bed communicating, by an upper substantially horizontal first face thereof, with said solid introduction means and, by a first substantially horizontal lower face thereof, with said solid removal means, said bed having two substantially vertical second faces closed by a sealed wall whose extensions beyond said bed form sealed walls of said individual distributor and said individual collector, at least one sealed wall connecting together the substantially horizontal upper sides of opposite wide faces of two solid beds next to each other, at least one sealed wall connecting together the substantially horizontal lower sides of opposite second faces of two solid beds next to each other. at least one sealed wall connecting the substantially horizontal upper side of the second face of the solid bed the closest to each wall of said reactor and substantially parallel to this wall, to said wall, at least one sealed wall connecting the substantially horizontal lower side of the second face of the solid bed the closest to each wall of said reactor and substantially parallel to this wall, to said wall, at least one general charge distributor, connected to said means for introducing the charge and to all the individual distributors of the charge by one of their substantially horizontal first faces, at least one general processed charge collector connected to said processed charge removal means and to all the individual collectors of the processed charge by one of their substantially horizontal first faces which is substantially diagonally opposite, with respect to the center of the corresponding solid bed, to the substantially horizontal first face of the corresponding individual distributor by which the latter is connected to the general distributor.
