Definitions
- the present invention relates to a method and a system for processing biomass.
- the system comprises a gasifier for the gasification of biomass to a gas mixture.
- the temperature of the gas mixture produced by the gasification is raised and an oxygen containing gas is added (such as air), wherein the energy of the following combustion reaction is used to supply thermal or electrical energy to an end user.
- an oxygen containing gas such as air
- Using the gas mixture as synthesis gas makes it necessary that a pipeline network is installed, for providing the synthesis gas from the gasifier to the chemical industry site.
- gasifiers for biomass are often installed in a decentralized manner, it is a great effort to install such pipeline network.
- the produced gas mixture may be stored in a pressurized state, which makes it necessary that the gas mixture is pressurized.
- the object is in particular achieved with a method for processing biomass, comprising the following steps:
- the present invention suggests to supply the gas mixture (or a fraction thereof) produced by the gasification of biomass (such as wood, energy crops or waste from forests, yards or farms) to solid particulate metal, so that the solid particulate metal reacts with the provided gas (in particular, a reduction rection between the metal comprising molecules - for example metal oxides - of the solid particulate metal with at least some of the gaseous components of the supplied gas occurs), while keeping its solid state.
- the particulate metal may be embodied by particles (granulate, pellets) comprising or consisting of a metal (such as iron, zinc, copper or alkali metal, for example magnesium), in particular a metal in its oxidized state.
- the particulate metal may be iron ore or iron ore pellets.
- the particulate metal After the treatment with the gas, the particulate metal is still in particulate (particle, granulate, pellets) form.
- the metal (molecules) of the particulate metal is in particular in its reduced state due to the treatment with the gas.
- the thus treated (reduced) particulate metal can be stored and transported/conveyed in solid form which makes the handling much easier. Accordingly, the chemical energy of the gas mixture produced by the gasification of biomass can be stored as bulk material.
- the treated (reduced) solid particulate metal can be used in an exothermic oxidation reaction, from which energy can be withdrawn.
- the oxidation reaction can for example occur in a fluidized bed reactor, to which an oxygen containing gas (such as air) is supplied for fluidizing the treated solid particulate metal.
- an oxygen containing gas such as air
- a water vapor comprising gas may be supplied to the treated (reduced) solid particulate metal preferably in a fluidized bed reactor so that hydrogen can be withdrawn from the following rection.
- the thus oxidized particulate metal may be further used in known processes.
- the treated particulate metal (which has a higher quality than untreated particulate matter) can be used directly in known processes, thereby saving energy in the known process.
- the gasifier for the gasification of biomass may be of the common type and can be embodied as moving bed gasifier, counter-current fixed bed gasifier, as co-current fixed bed gasifier, as fluidized bed gasifier or as entrained flow gasifier.
- the reactor for treating the solid particulate metal may be of any type of reactor known for treating solid particulate matter with a gas.
- the reactor may be embodied as fixed bed reactor, as fluidized bed reactor or as circulating fluidized bed reactor, in which the particulate metal is provided as particulate matter and to which the gas mixture (or a fraction thereof) is supplied as process gas.
- the outlet of the gasifier is connected to the fluidizing bottom of the fluidized bed reactor such that in use the particulate metal in the fluidized bed reactor is fluidized by the supplied gas mixture. This way the contact time of the gas with the particulate metal can be enhanced and thereby the efficiency.
- the gas mixture produced in the gasifier may be directly supplied (as a whole) to the reactor for treating the particulate metal. But, it is also possible that the gas mixture is withdrawn from the reactor and is treated (separated, distilled, fractionized) before it is supplied to the particulate metal in the reactor. Such a treatment unit would be arranged between the outlet of the gasifier and the inlet of the reactor. If necessary, storage vessels for the gas mixture o for a fraction of the gas mixture may be arranged between the outlet of the gasifier and the inlet of the reactor.
- the gas mixture produced by the gasification of biomass comprises a high content of carbon monoxide and as a further component hydrogen.
- the carbon monoxide and eventually the hydrogen react with the particulate metal within the reactor by a reduction reaction, so that the metal of the particulate metal is reduced. Accordingly, the carbon monoxide reacts with the particulate metal to (reduced) particulate metal and carbon dioxide.
- the hydrogen reacts with the particulate metal to (reduced) particulate metal and water.
- the whole process is carbon dioxide neutral.
- the produced gas mixture may be treated (for example distilled), such that the gas supplied to the reactor consists mainly of carbon monoxide, wherein only unavoidable impurities may be present.
- the system depicted in the figure comprises a gasifier 1, with a gas inlet 1.2 at its bottom and a biomass inlet 1.3 at its top.
- the gasifier 1 for the gasification of biomass also comprises a gas mixture outlet 1.1.
- the biomass supplied through the biomass inlet 1.3 is gasified within the gasifier 1, wherein the gases produced by the gasification of the biomass are withdrawn through the gas mixture outlet 1.1.
- the system further comprises a treatment unit 3, which is connected to the gas mixture outlet 1.1.
- the treatment unit 3 may be used to clean or distill the gases withdrawn from the gas mixture outlet 1.1.
- the outlet of the treatment unit 3 is connected to a reactor 2 of the system.
- the reactor 2 is embodied as fluidized bed reactor, wherein particulate metal can be supplied through a particulate metal inlet 2.2 into the reactor 2.
- the gas mixture produced in the gasifier 1 and eventually treated in the treatment unit 3 may be supplied through a gas inlet 2.1 to a fluidizing bottom 2.5 of the reactor 2.
- By supplying the gas through the gas inlet 2.1 the particulate metal within the reactor 2 is fluidized, wherein carbon monoxide and/or hydrogen of the supplied gas reduces the metal of the particulate metal.
- the reduced particulate metal may be withdrawn through a particulate metal outlet 2.4, whereas the reaction gases may be withdrawn through a gas outlet 2.3 at the top of the reactor 2.
- the chemical energy provided by the gas mixture produced in the gasifier 1 may be stored within the particulate metal treated in the reactor 2 and therefore in a solid state, wherein the whole process is CO2 neutral.
- the treated (reduced) particulate metal may be supplied to an oxidation reactor, in which an oxygen containing gas may be supplied to the treated particulate metal, so that an exothermic reaction is started from which thermal energy can be withdrawn.
- the treated (reduced) particulate metal my be supplied to an oxidation reactor, in which a water vapor containing gas may be supplied to the treated particulate metal, so that a reaction is started from which hydrogen can be withdrawn.
