20110271649 | Biomass Transport Installation for Introduction into a Pressurised Container - The introduction of a heterogeneous solid substance, such as biomass, into a container which is under pressure is difficult. The rotary valves and airlocks used hitherto have substantial deficiencies. The use of standard screw conveyors has hitherto failed due to the fact that a cavity formed behind the screw helix in which gas could escape from the pressurized container. These deficiencies are resolved in that two independently controllable screws are arranged in a screw conveyor pipe. Between the primary screw driven by a motor and the secondary screw driven by another motor, the biomass is compacted by high pressure as a consequence of the different revolution speeds of the motors in such a way that an almost gas-tight plug is formed. The invention is particularly well-suited for the introduction of biomass into a gasification installation which is under pressure, for the production of synthesis gas. | 11-10-2011 |
20120025140 | Method and Device for Producing Synthesis Gas from Gaseous Hydrocarbons - A method for the production of synthesis gas from gaseous hydrocarbons includes the use of allothermal steam reforming with catalysts. In order to produce the synthesis gas efficiently without exhaust gas in a compact apparatus, energy is at least partly supplied by electrical energy, that the energy is supplied by electrically heated contact surfaces and that the energy is supplied by contact surfaces within a fixed bed of catalyst pellets and/or within a fluidised bed at least partly consisting of catalyst particles. | 02-02-2012 |
20120091395 | Method and Device for Producing Low-Tar Synthesis Gas from Biomass - A method and device for producing low-tar synthesis gas from biomass. The method according to the invention lowers the tar content in the synthesis gas by splitting the biomass into pyrolysis coke and pyrolysis gas in a fluidized bed reactor, both of which are fed to at least one more fluidized bed reactor, wherein tars in the largely tar-free pyrolysis coke are catalytically split at a higher temperature without the ash melting point being exceeded. The method according to the invention enables the production of largely tar-free synthesis gas. | 04-19-2012 |
20120217440 | Method and Device for Using Oxygen in the Steam Reforming of Biomass - The invention relates to a device for using oxygen for the thermochemical gasification of biomass in at least one fluidized-bed reactor, a heating system being located in the fluidized bed of said reactor and the fluidized-bed reactor being heated by the at least partial oxidation of a combustible gas using oxygen. | 08-30-2012 |
20140346402 | Apparatus and Method for Natural Gas Reformation - An apparatus for the catalytic reaction of gaseous hydrocarbons into synthesis gas by means of oxygen is disclosed. In order to improve the apparatus it is provided for the catalyst chamber containing the gas and the catalyst particle to be separated from the oxygen chamber containing the oxygen by a gas-permeable wall. | 11-27-2014 |
20150013224 | Method and Device for Producing Synthesis Gas from Biomass - A method and a device for producing synthesis gas from biomass, wherein the biomass is decomposed into pyrolysis coke and pyrolisis gas in at least one pyrolisis reactor, the pyrolysis coke is introduced into the fluidised bed of a synthesis gas reactor and the pyrolysis gas is used as fluidisation gas for the synthesis gas reactor. | 01-15-2015 |
