Embodiment 1
[0031] use as figure 1 The apparatus shown, wherein the height of the fluidized bed section 1 is twice the height of the fixed bed section 2. The porosity of the porous distribution plate 3 is 30%, and the diameter of a single hole is 1 mm. On the cross-section of the fluidized bed section 1 0.5 m below the porous distribution plate 3, a 1 cm thick wire mesh layer 4 (platinum, with a porosity of 90%, and a single hole diameter of the wire mesh less than 0.01 mm) is set. At the central position of the perforated distribution plate 3 and the wire mesh layer 4, a water vapor injection pipe 5 (opening downward, facing the wire mesh layer 4) is arranged.
[0032] Through the catalyst inlet 8 of the fluidized bed section, a nanometer metal-supported catalyst (10% Fe-90% alumina, 1 nm in grain size) with an average particle size of 0.05 mm is charged into the fluidized bed section 1 . Through the catalyst inlet 10 of the fixed bed section, a nanometer metal-supported catalyst (90% ...
Embodiment 2
[0037] use as figure 1The apparatus shown, wherein the height of the fluidized bed section 1 is 5 times the height of the fixed bed section 2. The porosity of the porous distribution plate is 70%, and the diameter of the single hole is 8mm. On the cross-section of the fluidized bed section 1 1 m below the porous distribution plate 3, a 3 cm thick wire mesh layer 4 (stainless steel, with a porosity of 95%, and a single hole diameter of the wire mesh less than 0.01 mm) is set. At the central position of the perforated distribution plate 3 and the wire mesh layer 4, five water vapor injection pipes 5 (opening downwards, facing the wire mesh layer 4) are arranged.
[0038] Through the catalyst inlet 8 of the fluidized bed section, a nanometer metal-supported catalyst (10% Fe-90% alumina, grain size 20nm) with an average particle size of 0.5 mm is charged into the fluidized bed section 1 . Through the catalyst inlet 10 of the fixed bed section, a nanometer metal-supported catalys...
Embodiment 3
[0043] use as figure 1 The apparatus shown, wherein the height of the fluidized bed section 1 is three times the height of the fixed bed section 2. The porosity of the porous distribution plate 3 is 60%, and the diameter of a single hole is less than 3mm. On the fluidized bed section 1 cross-section 0.8m below the porous distribution plate 3, a 2cm-thick wire mesh layer 4 (nickel, porosity 92%, single hole diameter of the wire mesh less than 0.01mm) is set. At the central position of the perforated distribution plate 3 and the wire mesh layer 4, four water vapor injection pipes 5 (opening downwards, facing the wire mesh layer 4) are arranged.
[0044] Through the catalyst inlet 8 of the fluidized bed section, the nanometer metal supported catalyst (30% Fe-30% Co-10% Mo-30% magnesia, crystal grain is 5nm) with an average particle diameter of 0.1-0.3 mm is loaded into the fluidized bed In bed section 1. Through the catalyst inlet 10 of the fixed bed section, a nanometer metal...
