what is carbonization of biomass?

Biomass carbonization is the process in which biomass is heated under limited oxygen or completely oxygen-free conditions to undergo slow decomposition, releasing volatile components and producing solid biochar. In addition to biochar, combustible gases, and wood vinegar are also generated. The main by-product of carbonization is biochar, which is green and environment-friendly. How does biomass carbonization turn waste into wealth? The biomass carbonization plant is the best way to make money with the carbonization process.

The carbonization process is a necessary section of activated carbon plant. The carbonization process is to isolate the raw materials from the air and heat them to reduce non-carbon elements and produce carbonaceous materials suitable for the activation process. The carbonization process is the main preparation and foundation before the activation process.

Recovery of biological residues

At present, many biomass resources are not fully utilized, and most of them are recycled by nature through natural decomposition and carbon release. Our biomass carbonization plants can efficiently utilize biomass energy and reduce environmental pollution caused by energy consumption.

  • Various waste biomass: straw, rice husks, hemp stalks, sawdust, bark, bamboo powder, branches, coconut shells, walnut shells, palm shells, peanut shells, jujube stones, fruit peels, beef bones, coffee grounds, pine nuts, etc;
  • Various types of garbage and sludge: household waste, paper mill waste, municipal sludge, river sludge, industrial sludge, printing and dyeing sludge, etc;
  • Chemical lignite upgrading: carbonization of materials such as activated coke, blue coke, magnesium oxide, sodium oxide, etc.

carbonization machine

A complete biomass carbonization plant has to be equipped with a series of carbonization equipment, which is mainly composed of a silo, a hoist, a feeder, a continuous carbonization furnace, a refractory material, a rotating device, a temperature measuring device, a PLC control cabinet, a cooling device, a settling chamber, a fan, and a dust removal device. The carbonization kiln is definitely the core part of all carbonization equipment, it is where the carbonization process takes place.

carbonization furnace

carbonization furnace
carbonization furnace

The carbonization furnace, also known as carbonization kiln, continuous carbonization kiln, is composed of four major parts: feeder, carbonization furnace, flue gas purification system and cooling machine.

When the continuous furnace is running, the material is fed into the carbonization furnace through the feeder, because the carbonization kiln is almost a closed space, which satisfies the condition of less oxygen, so that the material is dry distilled at a high temperature of more than 600 degrees inside the carbonization machine, and carbonization occurs. The carbonized material passes through the carbonization machine to generate flue gas. After the flue gas purification system filter, the gas impurities such as wood tar fume, carbonized material is returned to the carbonization kiln for combustion, so that the thermal energy of the machine can run continuously, achieving the effect of smoke-free, environmental protection, and continuous. Finally, the finished charcoal is transported by the cooler to cool down, so that the temperature of the charcoal is only 50-80 degrees when it comes out. It is also possible to add mist spray equipment to cool the charcoal for a second time, so as to achieve the goal of completely eliminating the fire source.

highlights of carbonization Furnace

Good compatibility and wide application

It can be applied to a variety of biomass raw materials, which can be used for woodblock material, fruit stone material, powder material, and continuous carbonization of granular material and scrap material, with small limitations and high compatibility.

Smokeless carbonization design

Adopting a new innovative structure, the combustion exhaust gas can be discharged up to the standard, and the combustion flue gas can be fully utilized to achieve smokeless carbonization during the operation process.

Continuous operation, large-scale production

The continuous carbonization furnace overcomes the disadvantages of the traditional batch carbonization furnace, and through innovation, it can carry out efficient continuous production.

Low energy consumption

The production process of carbon/gas/oil co-production is realized, and the traditional defects of high energy consumption/large pollution/low efficiency are solved. In the carbonization process, tar/wood vinegar and combustible gas are all recovered by equipment and reused.

Carbonization process

As we mentioned before, our biomass carbonization process is not an isolated section, it is a new pattern of the recycling economy, we can realize various goals through the biomass carbonization process, reduce carbon emissions, recycle waste materials, produce many by-products, etc.

  1. The carbonization treatment process is not incineration, but a harmless cracking process (500-800 ℃). All organic harmful substances (such as solvents, plastic particles, lubricants and release agents, drug residues, PFAS, PCBS, PAK, etc.) can be eliminated during the carbonization process.
  2. Mineral pollutants (mercury, cadmium, etc.) will be separated or inert and will not return to the environment.
  3. The entire recycling process is a self heating reaction and provides a positive energy balance: only the energy generated during the waste carbonization process needs to drive the equipment.
  4. The generated heat energy can be used on the project site or connected to the local heating network.
  5. Reduce waste quantity and cost: up to 95%.

carbonization process for activated carbon

Activated carbon is an important application of biomass carbonization, so we list the carbonization process for activated carbon, if you want to start activated carbon plant, this will be more focused.

The activated carbon carbonization process is actually the dry distillation process of the material under low-temperature conditions. The material undergoes a series of complex physical and chemical changes under specific conditions. Ultimately, the purpose of carbonization is to form a secondary pore structure that is easily activated and imparts the mechanical strength required to withstand activation.

Material flow: The wood or nutshell is lifted by the conveyor into the charging chamber of the carbonization kiln, fed into the drum of the carbonization kiln by the action of the feeder, and brought to the copying board along the spiral movement in the drum, and the cylinder transfers the carbonization needs. After the first half of the preheating and drying stage, it enters the carbonization stage at 350-550 °C. During this process, the carbon particles are in contact with the heat to carbonize, discharge moisture and volatile matter, and finally discharge through the discharge port.

Gas flow: After the volatile gas generated by the carbonization kiln is burned in the combustion chamber, the cylinder wall of the rotary kiln is heated, and the flue gas after heat exchange is discharged from the chimney.
