Today pyrolysis oil can be used to replace fossil fuels and achieve a reduction in GHG emissions of 85-90% in heat and power applications. In the near future pyrolysis oil can be used as a starting point of the bio refinery and help lead us to a sustainable economy.
The market for sustainable, non-food energy and materials will experience huge growth in the decades to come. Explore our website to discover what a sustainable investment in a new pyrolysis plant may offer you, or contact us for more information.
As an industrial heat and power consumer, would you like to substitute your current fuel for one that is both sustainable and economical? In that case the use of pyrolysis oil may be an interesting option for you. You can retrofit your existing gas or oil boiler to run on pyrolysis oil and produce green heat and/or electricity today. Due to its GHG savings of around 90% pyrolysis oil can substantially reduce your companies CO2-footprint while at the same time reducing your dependency on fossil fuel prices.
Our pyrolysis technology is now mature. We can now multiply the concept and deliver actual pyrolysis plants to our customers. The pyrolysis oil can be used in boilers to produce heat and electricity at the moment of our customer’s choice. There is absolutely no need for the pyrolysis oil to be consumed at the time and place where it is produced. Production and use can be decoupled, and pyrolysis oil can easily be stored for a couple of years.
BTG-BTL pyrolysis process
Our pyrolysis process converts up to 70 wt.% of the biomass feedstock into bio-oil and the remaining part into char and gas. Since 1993 BTG has played an active role in numerous projects on fast pyrolysis. BTG's unique and patented pyrolysis technology is characterised by an intense mixing without the need for an inert carrier gas. BTG-BTL’s has taken BTG's patented RCR (Rotating Cone Reactor) fast pyrolysis technology and engineered it into a commercial industrial installation. The improved RCR design results in a remarkably small reactor, reduced system complexity and minimum down stream equipment size compared to competing pyrolysis technologies. A process flow diagram of BTG’s fast pyrolysis process is given below.
- Biomass particles are fed near the bottom of the pyrolysis reactor (bottom left) together with an excess flow of sand, which acts as circulating heat carrier material.
- The biomass and sand are mixed within the pyrolysis reactor and converted into pyrolysis oil vapors, gas and char.
- The produced vapours and gasses pass through several cyclones before entering the condenser, in which the vapours are quenched by re-circulated oil.
- The sand and char are transported to a fluidized bed combustor, where air is added to combust the char and reheat the sand.
- The hot sand is then transported back to the reactor to close the loop.
