Abstract
A method for reforming a liquid hydrocarbon mixture, in which the hydrocarbon mixture is initially completely vaporized before it is contacted with the gaseous reactants and caused to undergo reaction. Usable as a reformer system in this context is a device which has at least two reforming chambers composed of a vaporization chamber and at least one reaction chamber, and in which a metering device for liquid hydrocarbons is provided in the region of the vaporization chamber, and an introducing device for gaseous reactants is provided in the region between at least two of the reforming chambers. The present invention allows liquid hydrocarbon mixtures to be reformed without the formation of unwanted residues such as tar or soot.
Claims28
A method for reforming a liquid hydrocarbon mixture, comprising:
- (a) supplying the liquid hydrocarbon mixture continuously and in metered quantities;
- (b) vaporizing the liquid hydrocarbon mixture so as to achieve essentially complete vaporization and so as to produce a vaporized hydrocarbon mixture substantially without decomposition;
- (c) contacting the vaporized hydrocarbon mixture with at least one gaseous reactant so as to produce a gaseous hydrocarbon-reactant mixture;
- (d) causing the gaseous hydrocarbon-reactant mixture to undergo a reforming reaction so as to produce a reformate gas;
- and
- (e) directing the reformate gas toward an intended use.
Wherein the oxygen-containing gas mixture includes air.
A reformer device for reforming a liquid hydrocarbon mixture, the reformer device comprising:
- at least two reforming chambers disposed in a vessel, the at least two reforming chambers including a vaporization chamber and at least one reaction chamber;
- a metering device configured to meter a liquid hydrocarbon mixture, the metering device disposed in a first region of the vaporization chamber;
- an introducing device configured to introduce gaseous reactants, the introducing device disposed between two of the at least two reforming chambers.
The device as recited in 16 wherein the swirling device includes metal wire.
