- the present invention relates to a process for pyrolysis of woody biomass. It applies, in particular, to the recovery of wood residues (branches, leaves, shavings, sawdust, etc.) with the aim of producing bioenergy and bioproducts and helping to reduce greenhouse gas emissions. tight.
- the aim of the present invention is to provide the reactor core with optimal pyrolysis in order to ensure better homogeneity of heat exchange and ensure an optimal pyrolysis reaction.
- the present invention aims to remedy these drawbacks with a completely innovative approach.
- the invention aims to significantly improve the yield of the pyrolysis reaction and optimize the reaction extracts (bio coal, condensates, combustion gas, etc.).
- a process of pyrolysis of woody biomass remarkable in that it comprises the following stages: - a) mechanically grind woody biomass into woody particles less than 3cm 3 ; - b) transport the woody particles to a dryer operating at a temperature of at least 80°C configured to have a humidity level of less than 10% of the woody particles at the outlet; - c) heating the woody particles from the dryer, in a pyrolysis reactor with a horizontal trough and having an oxygen level less than 15% comprising a first inlet for the woody particles and a second inlet for heat transfer balls, the heating is configured to establish a temperature inside the reactor between 400°C and 660°C and configured to react the woody particles so as to have a first output of a mixture of heat transfer balls and pyrolyzed woody particles whose time presence in the reactor is at least 20 seconds and a second outlet of the pyrolysis gas;
- the aim of the process is to control not only the temperature of the heat carrier, but also the duration of heating time, in order to ensure that a temperature of 550°C to 660°C is reached at the center of the heat carrier and not at its surface only.
- the heat carrier stores the maximum possible thermal energy, guaranteeing better heat transfer capacity to the biomass in the pyrolysis reactor.
- the process was designed so that this targeted temperature of the beads at the reactor inlet can be ensured all the time, in a continuously moving environment.
- said method further comprises a step of separating the heat transfer balls and the pyrolyzed woody particles by sieving, said sieving comprises two outlets, a first for the heat transfer balls and a second for biochar.
- the sieving includes a grid which allows the separation of the heat transfer balls and the pyrolyzed woody particles.
- the grid is slightly inclined to allow, by the effect of gravity, the heat transfer balls to roll and bounce on the grid, which detaches the pyrolyzed woody particles which fall through the grid by the effect of gravity.
- said method further comprises a step of conveying in a vertical conveyor the mixture of heat transfer balls and pyrolyzed wood particles towards sieving.
- the dryer is a rotary type dryer and operates with combustion gases.
- the ball regenerator consists of a main cylinder crossed by cylindrical tubes through which the heat transfer balls pass.
- regenerator tubes are positioned substantially vertically.
- step d) the regenerator tubes are spiral.
- the heat transfer balls used in one of the steps of said process are made of metal, ceramic or a hard material having a diameter greater than 3 mm. This dimension makes it possible to have a sufficient diameter to retain the heat and allows good restitution of this heat in the reactor.
- the heat transfer balls used in one of the steps of said process have at least two different diameters with a diameter ratio less than or equal to 0.5.
- said method further comprises a step in which the pyrolysis gas from the reactor is routed into a condensation step configured to extract liquid phases.
- the pyrolysis reactor comprises a temporary storage zone for the pyrolysis gases, in which the storage zone is at least equal to 30% of the total volume of the reactor.
- the temporary storage area serves to eliminate the largest proportion of biochar in the gases in the hood in order to allow time for the biochar dust to settle while the gases exit at the top.
- the recovered raw material consisting mainly of residues from pruning and pruning operations (branches, leaves, shavings, sawdust, etc.), is delivered to a building by truck.
- the biomass is placed on a movable floor at the unloading dock.
- the contents of the truck are thus directly unloaded onto the first skip in a series of three skips with movable floors.
- the woody biomass is then sent to a grinding step 101.
- the grinding stage is, for example, a classic hammer mill, adapted to the needs of throughput and size of wood.
- the size of the woody particles obtained is less than 3cm 3 .
- crushed biomass is then transferred to a so-called crushed biomass bin, from where it is transported to the drying step 102.
- the latter is carried out inside a rotary dryer.
- the dryer operates at a temperature of at least 80°C and is configured to have a humidity level of less than 10% of the woody particles at the outlet.
- the dryer is installed in a closed container, supplied with heat by combustion gases coming from a combustion chamber presented below.
- the biomass is transported to the dried biomass bin before being transferred to a thermolysis reactor.
- This last bin is covered with a sheet metal roof in order to preserve the quality of the product and reduce losses into the air.
- biomass is stored in metal bins and that these are placed on dry ground, such as a concrete slab, all entirely outside. interior of the building, sheltered from bad weather and wind. It is therefore not planned to have biomass stored outside or which could pose an environmental issue.
- Emissions of wood particles are controlled through a series of cyclones, three for the crusher and one for the dryer.
- the particles captured by the cyclones are deposited in the appropriate bin to eventually be transferred to the pyrolysis reactor.
- the next step is to heat the woody particles in a pyrolysis reactor 103 with a horizontal trough and without oxygen.
- the targeted pyrolysis reaction is initiated when the dried biomass is heated to a temperature of around 450°C, in a low oxygen environment.
- the horizontal trough reactor comprises a cylinder into which an endless screw is inserted, where the biomass is mixed with steel heat transfer balls in order to optimize heat transfer and the thermolysis reaction.
- the dried biomass from the dried biomass bin is conveyed by conveyor to the pyrolysis reactor.
- heated steel heat transfer balls are also transported to the reactor to be mixed with the dried biomass.
- the pyrolysis reaction occurs and the biomass generates pyrolysis gases which are transferred to the condensation stage, detailed below.
- the biomass mixture reacts and the steel heat transfer balls are then recovered by a vertical conveyor, this is mixture 104 composed of pyrolyzed woody particles and heat transfer balls.
- biomass is separated from the steel balls by gravity through metal grids, then stored in bags to be marketed as biochar.
- the steel balls resume the closed loop of heating-reaction-separation.
- the pyrolysis gases go to a condensation stage 108.
- the pyrolysis gases are initially routed to the oil quenching.
- This equipment aims to condense as much bio-oil gas as possible, which is also a marketable product and which is temporarily stored in a double-walled, steam-heated, stainless steel tank. According to one example, it is located outside the building.
- the gases that have not condensed in the oil quench are then directed to the water quench which aims to condense mainly water.
- This water containing in particular acetic acid, is known as wood vinegar.
- wood vinegar is a product intended for marketing and temporarily stored in a double-walled, steam-heated, stainless steel tank. According to one example, it is located outside the building.
- the residual gases which have also not condensed in the quenches, the renewable gases, are then transferred to the combustion chamber to generate part of the energy necessary for the drying and reaction phases.
- the mixture 104 composed of pyrolyzed woody particles and heat transfer balls is directed by a vertical conveyor to the sieving step 106.
- Sieving is a step of separating heat transfer balls and pyrolyzed wood particles.
- the pyrolyzed wood particles and the heat transfer beads are separated by gravity through metal grids, the beads remain above the grid while the pyrolyzed wood particles fall by gravity.
- the pyrolyzed woody particles are stored in bags to be marketed as biochar.
- the heat transfer balls after the sieving stage are sent to the regenerator stage 107.
- the ball regenerator consists of a main cylinder crossed by cylindrical tubes through which the heat transfer balls pass.
- the tubes are positioned substantially vertically.
- the tubes have the shape of a spiral.
- the horizontal trough reactor is used for the pyrolysis of previously dried biomass.
- the biomass and heat transfer balls are introduced to the reactor through their respective inlets N1 and N2 at one end of the reactor.
- the heat transfer balls and the biomass are mixed and transported to the other end of the reactor.
- the biomass is pyrolyzed using the energy transferred by the balls which have previously been heated in a regenerator.
- a temporary storage area is created.
- the size of this temporary storage zone is at least equal to one third of the total volume of the reactor.
- the temporary storage area serves to remove the largest proportion of biochar in the hood gases to allow time for this dust to settle while the gases exit through the top of the hood.
- An N6 hot gas inlet and an N7 hot gas outlet are positioned at the ends of the reactor.
- Oil vapors are also produced and routed to a pyrolysis oil and wood vinegar recovery unit.
- the oil portion having a biochar concentration exceeding 1% in the pyrolysis oil (substrate) from the oil condensation unit is recycled to the reactor to be pyrolyzed again in N3.
- a jacket is installed around the reactor in order to circulate hot gas coming from the outlet of the ball regenerator. This is to keep the walls of the reactor hot.
- a separation grid made of parallel metal bars is used to separate the beads and the biochar coming from the pyrolysis reactor at the T1 inlet.
- the space between the bars allows the biochar to flow by gravity or with the help of a pressure variation device in T2 through the grid and the balls to roll towards the inlet of the regenerator in T3.
- This separation grid is inserted into a pipe.
- the grid is inclined by at least 25° relative to the horizontal, which allows the heat transfer balls to roll and bounce on the grid while allowing pyrolyzed woody particles to detach from the heat transfer balls.
- the separator is chambered with hot combustion gas from the regenerator in order to maintain the stability of the gas temperature in the reaction loop equipment. All this avoiding temperature differences which can create condensation or have a consequence of the chemical composition of bioproducts
- regenerator used in step d) of heating the heat transfer balls.
