from WOOD WASTE to

BIOCHAR

Biochar is a form of charcoal that is obtained from pyrolysis of biomass. It has many uses e.g. in carbon storage, agricultural soil improvement and filtering applications. Biochar with a high fraction of carbon (>90 %) can also be used in steel industry. Depending on process parameters like used feedstock, process temperature and retention time, the physical- and chemical properties of biochar can vary a lot. When using wood chips from forestry residues, our technology produces biochar with a very high carbon content (>94%)

SYNGAS

When producing biochar, most of the volatile components of wood evaporate. This results in formation of wet and tarry pyrolysis gas, containing H2, H2O, CO, CO2, CH4 and tar. With Xylo Gas‘ state-of-the-art technology, this hard-to-handle gas is reformed into clean syngas. The gas composition (~60 % H2 and ~30 % CO) and the absence of nitrogen and tar makes it a valuable product with wide variety of applications.
* raw material for liquid (methanol, SAF) or gaseous (methane) biofuels
* replacement for natural gas and fuel oil in industrial processes and heating
* fuel for CHP applications

HEAT

Our integrated biochar and syngas technology also produces heat. In our cold and moist climate, a fraction of the produced heat is needed for drying the fuel before feeding it into the process. By using dry fuel (< 10 % humidity) production of liquid pyrolysis byproducts can be avoided.

Thanks to its unique design, this open style flare works well with wood gas, syngas and also with a variety of other gas mixtures including hydrogen, carbon monoxide, methane and carbon dioxide. Our customer is using this for flaring start-up gases from eMethane.

Wood gas burner used for charring timber. Xylo Gas designed, built and installed a wood gas burner system including burner, control unit, safety flare and pipelines. This particular burner is replacing a natural gas burner and is using wood gas produced on site.

A robust and mechanically cleaned dry filter for high-temperature gases e.g. wood gas, syngas, flue gas. Controllable pressure drop.

During 2014 – 2019 Xylo Gas went through a dense R&D phase of fixed bed co-current gasification technology. Several iterations were built including a semi-automated oxygen fed gasifier. The latest fully automated version produces wood gas that is used for production of heat and power at a manor in south-western Finland.

Xylo Gas’ novel technology producing high-quality biochar (carbon content >94%) and hydrogen rich, nitrogen-free syngas (~60 % H2 and ~30 % CO).

In Xylo Gas Oy we develop and deliver bioenergy cleantech solutions.

History
Our story started in the early 2000s with the development of a wood-gas-powered car by company founder Fredrik Ek, current CEO. Over two decades, we have delivered wood gasification systems, as well as burners and flares for various gases to customers in Finland.

Vision
Our vision is a resource efficient and carbon negative bioenergy sector - fully utilizing sustainable forestry residues and waste wood with minimal emissions and biodiversity impact. In our view, the key is to produce as much value as possible from a given resource.

Xylo Gas today
With background in thermal gasification, we recently extended our portfolio into biochar production. We have combined a pyrolysis concept with indirect gasification in a novel way. Consequently, we invented our current key product, a clean and compact state-of-the-art thermal gasification/ biochar process technology. The technology is now in the phase of a working prototype built in spring 2024.
