BTG Bioliquids BV(BTG-BTL)
› BTL is ready to implement its pyrolysis technology on acommercial basis today!
› Why biomass?– Reduction of the use of fossil fuels (coal natural gas, oil)– Reduction greenhouse gases (in particular CO2)– Security / diversity of energy supply– Cheaper ?
› Why is biomass not used?– Contaminants– Availability (MJ versus GJ)– Structure (….) - complexity of material– Energy density

Why Pyrolysis?
› Tradable liquid products as main
product from biomass (≤70%)
› Minerals remain in char / ash
› High fuel flexibility
› Increase in energy density with a
factor of 4 - 5 (wood) to 10 - 20
(fibrous, wet EFB)
› Linking agriculture to (petro)-
chemical industry
Decoupling in biomass resource, location, time and scale

Training course on Renewable Energy
What is pyrolysis?
Principle– Fast chemical degradation due to rapid
heating in absence of oxygen– The main product is a liquid: Bio-oil
Conditions– 500°C, 1 atm.– Small particles (< 3 mm)– Rapid heating– Short residence time of the product– Rapid quenching
