Definitions
- the equipment of catalytic thermo-fission of this industrial invention uses ethyl alcohol coming from renewable source as raw material and it has the peculiarity that from the reactor we obtain gaseous hydrogen and carbonic oxide.
- Fig. 1 shows the equipment overall layout, the ethyl alcohol is stocked in the tank
- the ethanol vapours coming out from the heat exchanger get into the catalytic reactor Rc (shown in Fig. 3) that is at temperature Tu.
- the gaseous mixture goes through a separator at molecular sieves ⁇ m (shown in
- the hydrogen goes in the clearing device ⁇ (shown in Fig. 4) and is stocked up in the holding tank S3, from which, after a pressure reduction, it flows, with a specific delivery measured by the flux meter F2, to fuel cell (Fuel cell).
- the generated electric energy is introduced to a proper circuit controlled by a PLC composed by a group of storage batteries and ultra-capacitors that supply the traction electric motor Me.
- the carbon monoxide is introduced to the holding tank S2 and then, after a pressure reduction and with a specific delivery Ig, it goes into the tubular burner, Philips type, (shown in Fig. 6) in which preheated air Ea is introduced as combustive (the preheated air comes from the heat exchanger E2 under force carried out by the fan v driven by the small motor m3).
- the burner, radiant tube type, is immersed in the diathermic fluid f ⁇ to which it transfers the thermal energy Q at temperature Tl.
- the diathermic fluid f ⁇ through the tube system heat exchanger E3 produces steam
- Vm at temperature T2 and delivery pressure Pe that are the suitable conditions necessary to drive the rotary steam motor Mv, which by a silent chain controls the rotation of the hydraulic pump Pi that allows the driven of the hydraulic motors ml, ml, m3, m4.
- the steam coming out from the motor Mv at temperature ts flows inside the heat exchanger E2 (preheater of combustive air) through the pump p2 driven by the hydraulic motor ml.
- the steam after having transferred some of its heat, returns inside the tube system heat exchanger E3 that feeds the motor Mv at closed circuit.
- the thermal oil pump P3 driven by the hydraulic motor m4, makes the diathermic fluid f ⁇ circulate toward the heat exchanger El and the catalytic reactor Rc producing the working optimum temperature.
- Fig. 2 shows in detail the sectional view of the evaporator El in which the ethyl alcohol flux Ia goes through the check valve 6, connected to the head 3, inside the coil S 5 fixed to the bottom plate 2, reaching the outgoing temperature Te inside the flange compartment 1, and then going out through the output duct Uv.
- the diathermic oil at temperature Tk goes in through the duct Ef ⁇ , then flowing it makes the exchange Q with the coil S and finally it goes out through the duct Sf ⁇ .
- the whole device bounded by the end bottom plates 4, is contained inside aluminium concentric tubes Ci (reflecting for thermal radiations) with an hollow space made by thermal-insulation material J ⁇ .
- Fig. 3 shows in detail the sectional view of the catalytic reactor Rc placed in sequence to the evaporator El.
- the alcohol vapours Ev at temperature Te go in the catalytic reactor Rc through the entry duct 9 and then going out at pressure Pe from a series of small holes laid out in radial mode at the edge of the duct.
- a special catalytic net Rc* consisting of a metallic thread composed by a ternary alloy 70% tin, 20% germanium, 10% lead.
- the ethyl alcohol vapours going out from the duct small holes crossing the net mesh are subjected to a partial fission to carbonic oxide and hydrogen.
- the gaseous mixture flux goes out through the large number of very small holes of the diaphragm di to reach the chambers K3-K2-K1 spaced by stainless steel bored diaphragms inside which there are the catalytic separators made by a siliceous support with active places of a mix of microcrystalline porous powders of 60% nickel, 20% titanium, 15% cobalt, 5% iron.
- thermo-fission device is located between the edge heads 7 and 12 heated at temperature Tr by the thermal fluid F ⁇ flowing inside the block 10.
- the concentric aluminium tubes Ci and the insulation hollow space J ⁇ act as reactor container.
- Fig. 5 shows in detail the sectional view of the separator that split the two components CO and H 2 coming from the catalytic reactor Rc.
- the molecular sieve 20 ( ⁇ m) is inside the body 19, it allows the passage of H 2 molecules and it convoys them in the annular hollow space to exit through the port
- Fig. 4 shows in detail the sectional view of the device for the purification of the hydrogen coming from thermo-fission.
- the gas goes into the tank 16 through the check- valve 14, it passes through the solution 17 (Sa absorption solution ppm of residual CO) and it is convoyed in the duct 15 to which edge 13 there is a clearing the fog net rs and it goes out from the dome through the duct Uf that is suitable to feed the fuel cell for the electrical energy generation.
- solution 17 Sa absorption solution ppm of residual CO
