Definitions
- the present invention relates to the field of recycling end-of-life wood or waste wood. More particularly, it relates to a process for upgrading biomass consisting of end-of-life wood or waste wood by steam cracking with a view to the manufacture of solid fuels. It makes it possible to recover processed wood intended for material recycling, landfill or incineration.
- biomass Apart from biomass, river or dam hydraulics, and geothermal energy, these renewable energies are intermittent unless the means of energy storage are developed. And only biomass constitutes primary energy that can be transported to its place of transformation into heat and / or electricity. But biomass is in fact a low density, variable and perishable energy.
- the so-called “A” wood is composed of uncoated, untreated wood packaging waste.
- the so-called “B” wood is composed of non-hazardous wood waste containing a small amount of additives or other materials; glued wood, wood having received a surface treatment (preservation, finish) or a coating (wallpaper, melamine, polypropylene ).
- this category includes panels, furniture wood, demolition wood free of rubble, etc ...
- C wood is made up of hazardous waste (creosote wood for example) destroyed in a special waste incineration plant or used in cement kilns.
- OSB, MDF, HDF plywood or particle board
- type B wood which today is intended for material recycling, landfilling or incineration.
- type A wood when it is used in combustion, it is only crushed, without being granulated.
- Steam cracking differs from hydrothermal pretreatment, also known as aqueous fractionation, solvolysis, hydrothermolysis or hydrothermal treatment, in that the latter involves using water at high temperature and pressure to promote the disintegration and separation of the gas. lignocellulosic matrix. This technique is not suitable for the production of black granules since the products obtained are predominantly liquid.
- Pyrolysis is the chemical decomposition of an organic compound by intense heating in the absence of oxygen.
- the compounds obtained after pyrolysis differ in their characteristics of those obtained by steam cracking. Steam cracking cannot be likened to a pyrolysis technique in that it employs a steam explosion and is carried out in the presence of oxygen.
- US2013 / 225714A1 relates to a method of modifying a molecular structure of a biomass feedstock comprising converting a treated biomass feedstock into a product, using a microorganism.
- the treated biomass feedstock having been prepared using a biomass treatment method, including a steam explosion method.
- US2015 / 196893A1 describes a biorefining process for co-producing activated carbon from various biomass streams. This process uses pyrolysis methods.
- the method according to the invention allows the production of solid fuels from lignocellulosic biomass consisting of wood A and / or wood B. It consists of a process for upgrading lignocellulosic biomass consisting at least in part of wood from end of life or non-granulable wood-waste after grinding, characterized in that a preparation step of said biomass is applied, consisting in removing at least part of the elements other than wood, then in carrying out a treatment step thermal by steam cracking followed by a granulation step.
- the present invention therefore proposes a new approach for recovering wood that is transformed, aged or more generally considered to be at the end of its life and intended for material recycling, landfill or incineration.
- the processed wood generally exhibits a modification of the lignocellulosic fibers which makes them not very usable. Indeed, waste wood is drier and its intrinsic characteristics are different from that of young wood.
- the effect of steam treatment makes it possible to break down the other components present in wood (glues, resins, additives, etc.) and therefore to participate in a granulometric standardization of the product and a homogeneous distribution of these molecules avoiding singular zones which could be zones of less good granulation efficiency.
- the heat treatment in addition to chemically degrading certain exogenous molecules results in a dark coloration of the product (future black granulate). This coloring attenuates the presence of dyes and pigments added to the wood A and B, and contributes to its acceptance by the user.
- the process for preparing granules by steam cracking has the advantage of producing granules with a uniform and constant visual appearance, which is a mark of quality for the consumer.
- the process more generally allows better granulation than in the case of the preparation of white granules from the same substrate.
- the process avoids the use of additives or the use of expensive resinous supplemental natural wood to promote the cohesion of the pellets.
- An object of the invention relates to a process for upgrading lignocellulosic biomass consisting at least in part of end-of-life wood or non-granulable waste wood after grinding, characterized in that a step of preparing said is applied. biomass consisting in eliminating at least some of the elements other than wood, then in carrying out a heat treatment step by steam cracking followed by a granulation step.
- end-of-life wood or wood-waste we mean any processed or aged wood, more particularly wood qualified as wood A or wood B according to the ADEME classification. This wood cannot be granulated directly after grinding.
- the purpose of the wood preparation stage is to reduce the final contaminant content.
- contaminant any substance detected in a place where it is not normally found. In the case of contaminated wood, it is any substance that is not naturally found in the wood. Examples of contaminants frequently found in wood are paint, plastic (coating, decoration, handle, buttons, etc.), metals (nails, hinges, locks, etc.), glass, adjuvants such as glue, resins, polymers, phytosanitary products, melamine, etc ...
- Wood preparation consists of removing residues of glass or metals or plastics or mineral residues. It can be implemented by optical, densimetric, magnetic or mechanical sorting. These treatments can be carried out manually or automatically.
- the treatment consists in removing certain excessively contaminated wood. Indeed, it is recommended to carry out a selection of wood A and B, and especially a fine selection of wood B to avoid the presence of too many exogenous elements which are not binding for granulation, in particular plastics. Obviously, the presence of inert materials (ironwork metals, glass, etc.) as well as polymers (plastic plating, PVC fields, etc.) should be avoided. Also the supply chain should include sorting and selection operations. Afterwards, the process will have to include a good phase of securing the tools (grinding, iron removal, de-stoning to remove heavy material pollutants, possibly sorting and visual verification), then the process becomes classic again with possibly drying, then steam cracking and granulation.
- the producers of black pellets obtained from wood A or wood B are industrialists who seek to optimize the production of biofuels by using local resources from the recovery and valorisation sectors of end-of-life wood, thus benefiting from a tariff of lower purchase, but still easy use of the product in biomass boilers, and economically replacing coal or gas, to date inexpensive fuels, and participating in a circular ecology that respects the environment.
- the users of the black pellets obtained from wood A or wood B are all users of biomass boilers.
