Claims
- 1. An apparatus for producing a reaction product gas, comprising: an elongated reactor shell having a cylindrical wall, an upper wall at the upper end thereof and a bottom wall at the bottom end thereof; a horizontal top partition wall disposed inside said reactor shell and located close to said upper wall, said upper wall and said top partition wall defining a top space therebetween; first and second, gas-permeable, upright, cylindrical partition walls extending between said top partition wall and said bottom wall, said first partition wall being disposed within and being inwardly spaced from said second partition wall, said first partition wall defining therewithin a vertically elongated central space extending from said top partition wall to said bottom wall, said first and second partition walls defining a catalyst space therebetween; said second upright partition wall being radially spaced inwardly from said cylindrical wall of said reactor shell to provide a peripheral space therebetween, the upper end of said peripheral space communicating with said top space; a gasification catalyst bed disposed in and substantially filling said catalyst space between said first and second partition walls and said top partition wall and said bottom wall; first feeding means for feeding a reactant mixture of hydrocarbon and gasification agent to said gasification catalyst bed, said first feeding means comprising a supply tube extending through said top space and communicating with said central space so that the reactant mixture flows through said central space and thence through said gasification catalyst bed and is reacted therein to generate reaction product gas which then flows into said peripheral space and thence into said top space; first exhaust means comprising a reaction product outlet tube communicating with said top space for discharging the reaction product gas; a combustion shell disposed below said reactor shell and comprising a bottom wall, a cylindrical side wall and a top wall; a lower internal partition wall spaced upwardly from said bottom wall of said combustion shell and defining a collection section therebetween; third and fourth, gas-permeable, upright, cylindrical partition walls extending between said top wall of said combustion shell and said lower partition wall, said third partition wall being disposed within and being inwardly spaced from said fourth partition wall, said third partition wall defining a central vertically elongated inlet chamber, said fourth partition wall being spaced from said cylindrical side wall of said combustion shell to provide an open space therebetween; second feeding means for feeding a stream of a fuel mixture of gaseous fuel and an oxygen-containing gas to said inlet chamber; said third and fourth partition walls defining a second catalyst space therebetween; a combustion catalyst bed disposed in and substantially filling said second catalyst spaced between said third and fourth partition walls so that said fuel mixture flows from said inlet chamber into and through said combustion catalyst bed and is catalytically burned therein to generate heat of combustion and a flue gas; second exhaust means for discharging the flue gas from said apparatus, said second exhaust means comprising said collection section so that the flue gas flows through said fourth partition wall, said open space and said collection section; a plurality of elongated heat pipes extending upwardly from said combustion shell into said reactor shell, each of said heat pipes having a vaporization section positioned in said combustion catalyst bed and a condensation section positioned in said gasification catalyst bed so that said heat pipes receive the heat of combustion generated in said combustion catalyst bed and transfer it to said gasification catalyst bed.
- 2. An apparatus as claimed in claim 1 in which said top wall of said combustion shell is the bottom wall of said reactor shell.
- 3. An apparatus as claimed in claim 1 comprising additional heat pipes whose vaporization reactions are disposed in said open space between said cylindrical side wall of said combustion shell and said fourth partition wall.
- 4. An apparatus as claimed in claim 1 in which said combustion shell has an upper internal partition wall disposed between said top wall and said lower internal partition wall, said combustion catalyst bed filling the space between said upper and lower partition walls.
- 5. An apparatus as claimed in claim 1 in which external fins are provided on the vaporization sections of said heat pipes, said fins extending into said catalyst bed means.
- 6. An apparatus as claimed in claim 1 in which each of said heat pipes is closed and the interior of it is maintained at a high vacuum, each of said heat pipes being packed with sodium metal or lithium metal.
