Definitions
- the invention relates to a process for the gasification of pyrolysis condensates according to the first claim.
- the pyrolysis is a good way. Especially wood waste, but also other dry lignocellulosic waste, can be achieved by rapid pyrolysis, in which the waste for a few Seconds to high temperatures, effectively convert to a so-called bio-oil.
- the bio-oil so obtained has some crucial Disadvantage. Above all, it is not stable and storable. Much more after a more or less long time, it tends to segregate, wherein an aqueous and an organic phase form.
- the aqueous phase can be more or less large quantities water-soluble organic compounds, in particular Acetic acid, alcohols and other hydrocarbons Oxygen or other heteroatoms.
- the bio-oil can be used in a carburetor, especially in an airstream pressure carburetor be implemented to a higher quality To obtain energy sources.
- the bio-oil in the air flow gasifier with pure oxygen in substoichiometric Ratio implemented.
- the invention is therefore based on the object, a method for the gasification of pyrolysis condensates, in which the Flugstromvergaser can be safely operated.
- the other Claims become preferred embodiments of the method specified.
- the basic idea of the invention is demixing of bio-oil in order to obtain a safe
- the bio-oil separated into an aqueous and an organic phase become.
- the organic phase contains sufficient in each case high calorific value to dangerous operating conditions in the To avoid entrainment gasifier; It therefore becomes continuous and fed without interruption the Flugstromvergaser.
- the aqueous phase is fed separately into the entrained flow gasifier, it is irrelevant whether the feed is continuous or intermittently - at intervals, for example. This way it can not become a superstoichiometric Concentration of oxygen in the carburetor come.
- the feed can be in two different feed nozzles, but also take place in a common feed nozzle.
- the separation of the bio-oil into the two phases is preferred carried out in such a way that the organic phase at best a low water content, definitely a water content below 25, better below 20 wt .-%.
- the water content In contrast, the aqueous phase is preferably at least 50% by weight.
- the two phases can be among these Conditions are stored for a long time and are no longer prone to a new phase separation.
- the separation of the bio-oil into the two phases is preferably carried out by fractional condensation during generation of the Bio oils in the fast pyrolysis.
- the fast pyrolysis carried out with lignocellulose, taking the lignocellulose with sand or another suitable heat carrier, the a temperature of 500 ° C to 600 ° C, for the duration from 1 to 10 seconds.
- the educated Bio-oil is subjected to the mentioned fractional condensation, so that the described two phases arise. alternative could bio-oil by prolonged storage and decanting in two phases are separated.
- Both the organic and the aqueous phase prove as long-term stable, so that against a longer, separate Storage no safety concerns exist. Both phases can with or without the addition of 3% by weight straw ash at room temperature for example, over a period of 15 months be stored in sealed gas cylinders, without that a significant segregation occurs. Composition, Density, calorific value and viscosity remain over the storage period practically the same.
- one or both phases can be before the feed in the gasifier powdered pyrolysis and / or a Slag fur formers are mixed.
- the pyrolysis coke stabilized the operation of the carburetor because of the additional Fuel while through the slag fur builder the interior carburetor against corrosive and aggressive conditions is protected.
