The Institute of Energy offers consumers a Stand for obtaining liquid pyrolysis products under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

Biomass pyrolysis is the thermal decomposition of organic materials at high temperatures (300–700°C) in the absence of oxygen. One of the key products of this process is liquid products known as bio-oils or pyrolysis oils. These substances are complex mixtures of organic compounds and are used in the energy, chemical, and other industries.

The main stages of producing liquid pyrolysis products are:
1. Feedstock preparation:
- Biomass (e.g., wood, agricultural waste, straw) is crushed and dried to a moisture content of less than 10%.
2. Pyrolysis process:
- Biomass is heated in a reactor to a temperature of 400–600°C in the absence of oxygen.
- The heating rate and temperature determine the yield of liquid products:
- Slow pyrolysis: low heating rate, higher solid product yield (char).
- Fast pyrolysis: high heating rate (up to 1000 °C/s), maximum yield of liquid products (up to 75% of the feedstock mass).
3. Vapor condensation:
- The vapors formed during pyrolysis are cooled in a condenser, where the liquid products (bio-oil) are separated.

Characteristics of liquid pyrolysis products:
- Composition: complex mixture of water, organic acids, ketones, aldehydes, phenols, hydrocarbons, and other compounds.
- Energy value: 16–19 MJ/kg (lower than traditional fuel due to the high content of water and oxygen-containing compounds).
- Viscosity: high, requiring additional processing for use in engines or boilers.

Applications of liquid pyrolysis products:
1. Power engineering:
- Used as fuel for boilers, turbines, and diesel engines.
2. Chemical industry:
- Serves as a raw material for producing chemical compounds such as phenols, acetic acid, and methanol.
3. Biofuel production:
- After processing, bio-oil can be converted into biodiesel or synthetic fuel.
4. Fertilizer production:
- Some bio-oil fractions can be used to improve soil properties.

Leading technologies and companies:
1. BTG Biomass Technology Group (Netherlands):
- Specializes in the development of fast pyrolysis technologies.
2. Ensyn Corporation (USA):
- Produces bio-oil for the energy and chemical industries.
3. Pytec Thermochemische Anlagen GmbH (Germany):
- Develops biomass pyrolysis systems.
4. Dynamotive Energy Systems (Canada):
- Developer of fast pyrolysis technologies for bio-oil production.

The main components of the setup developed at the Institute of Energetics are two thermally insulated reactors on a support frame, connected by a duct. Each reactor is supplied with air by a blower. The reactors also have dampers and outlets to the heat exchanger and storage tank.

To bring the setup to its thermal mode, the reactors are equipped with electric heaters. The setup also includes valves, a smoke stack, and measuring instruments for monitoring the temperatures inside the reactors, heat exchanger, and storage tank.

Information is available on the official website of the Institute of Energetics here.

Characteristics of the resulting liquid pyrolysis products:
• The resin density is 0.9 g/cm³.
• Viscosity was determined using a Brookfield DV2T rotational viscometer at a temperature of 17.1⁰C. The measured value was 395±4 cP.
• Flash point was determined using a TVZ-LAB-11 automatic apparatus and was 190⁰C.
• The calorific value of the resin was 28,766.78 kJ/kg (6,870.83 kcal/kg). Calorific value was determined using a V-08MA "K" calorimeter.
