Abstract
The apparatus comprises a central, axial and radial air-permeable air inlet (7), a catalyst system arranged concentrically on a portion of the length of the air inlet, a buffer zone (3) concentric to the catalyst system, an absorbent material (4) concentrically arranged around the buffer zone for fuel distribution, a gas-tight sealing element, and a heating element integrated between a pair of any of the above components. The heating element is designed as electrically insulated heating wire on/in the catalyst system as an inductive heating by direct heating of the catalyst system. The apparatus comprises a central, axial and radial air-permeable air inlet (7), a catalyst system arranged concentrically on a portion of the length of the air inlet, a buffer zone (3) concentric to the catalyst system, an absorbent material (4) concentrically arranged around the buffer zone for fuel distribution, a gas-tight sealing element, and a heating element integrated between a pair of any of the above components. The heating element is designed as electrically insulated heating wire on/in the catalyst system as an inductive heating by direct heating of the catalyst system, where the system is heated by a chemical, exothermic reaction, or over hot gas or exhaust gas. The absorbent material is fluidically connected to a point in the air inlet for the liquid fuel, and consists of non-woven materials, sponges and/or fiber materials. The components of the device are thermally decoupled by a reactor jacket (6). The air supply is formed as a tube with radial and axial holes, a sintered body, a porous structure, metal foam, membrane, ceramic foam or glass frit. The catalyst system comprises a layer of a catalytic active substance or a wash-coat applied on a support, and is connected directly with the air inlet or separated from the air inlet by a gap. The support is present in the form of fibers, foams, nets, pellets, packed bed, extrudate, sheets, non-woven materials and/or porous bodies. The buffer zone is designed as coiled tubing, meander, mesh, net, air gap and/or pins. An INDEPENDENT CLAIM is included for a method of vaporizing liquid fuels.
