Background technology
Along with the exhaustion day by day of petroleum resources, the continuous increase of energy requirement amount, the whole world faces energy starved crisis gradually.Biofuel, as a kind of renewable energy source, is subject to the attention of various countries and is developed energetically.But in the process of preparation biofuel, often produce the glycerin by-products that 10 tons of biofuel can produce about 1 ton, effective utilization of by-product glycerin has become the important factor affecting biofuel enterprise development.Take glycerine as starting material producing synthesis gas (hydrogen and carbon mono oxide mixture), synthetic gas is a kind of industrial chemicals, also can as fuel, so improve glycerine utilize space.Utilize the main method of glycerine synthesizer to be catalytic reforming at present, there is the problem of poisoning of catalyst.
Summary of the invention
For solving the problem, the present invention proposes a kind of reforming plasma glycerine preparing synthetic gas method.
The present invention, for reaching above object, is realized by following technical scheme:
There is provided a kind of reforming plasma glycerine preparing synthetic gas method: 1) glycerine is introduced plasma generator after being atomized; 2) electrode in plasma generator imposes high-voltage, central electrode and outer electrode are under high voltage electric effect, center electrode tip and the narrowest place of outer electrode produce and puncture electric arc, the following high speed rotating of its glycerine at eddy flow spraying promotion sweeps away limit, inter-electrode space and moves to producer downstream, until the long cancellation of electric arc, said process constantly circulates, and produces Non-thermal arc plasma body, induced by plasma glycerine generation reformate chemical reacts, and produces synthetic gas.
Described plasma generator, comprises central electrode, polytetrafluoroethylene floor, outer electrode, cylinder outer wall, opening for feed and air outlet; The central electrode of producer, polytetrafluoroethylene floor, outer electrode, cylinder outer wall and air outlet axis are all positioned on cylinder outer wall axis, and wherein central electrode is the cuspidated copper rod of a band, and dispatch from foreign news agency is a bronze medal de Laval noz(zle) very, and cylinder outer wall is stainless steel tube; Central electrode and outer electrode are separated by polytetrafluoroethylene floor, the narrowest distance 0.5-5mm between two electrodes; Glycerine tangentially enters plasma generator by the opening for feed be fixed on cylinder outer wall.
Because carbon-to-oxygen ratio in glycerine is 1: 1, extra oxygen element (as water or oxygen) can be needed so transformation of glycerol is synthetic gas:
