Willow Fractionation

Jean-Michel Lavoie, Ph.D Industrial chair on cellulosic ethanol Michel Chornet, Ing. CRB Innovations

What is the target?

• Willow energy crops (Agro Energie + IRBV)
• Content:

– Cellulose – Lignine – Hemicellulose – Proteins – Extractives

• Objective - Upgrading the fractions

– Green fuels and green chemicals

What is « fractionation »?

• Using the FIRSST process:

– Separation of the lignocellulosic matrix – Using steam treatments

• The isolated fractions

– Converted independently

• The end products

– Ethanol, biodiesel, biojetfuel, green compounds

• Low secondary products, low CO2 emissions

Ethanol/green chemicals

• From 1 tonne of Salix viminalis

– 267 litres of EtOH – 83 litres of p-fuels (biodiesel) – 197 litres of l-fuels (bio jetfuel) – 40 kg of added-value molecules

• From 1 tonne of Salix miyabeana SX67

– 304 litres of EtOH – 54 litres of p-fuels (biodiesel) – 184 litres of l-fuels (bio jetfuel) – 40 kg of added-value molecules

*Energy requirement 13 GJ/tonne

Our approach

Non-homogeneous biomass 0.7 tonne (dry basis) + moisture

FIRSST Gasification

Quasi-homogeneous biomass 1 tonne (dry basis) + 1 tonne moisture

Biofuels

Water: 1017 kg CO2: 252 kg Solid residues (rich in N and K): 5 kg

Green chemicals : 40 kg EtOH : 250-300 l Biodiesel : 50-80 l Jetfuel : 180 l

Residues (216 kg dry basis) Steam/O2

CHP

Water: 210 kg Solid residues (<5% unconverted C)

Syngas

CO2 removal CO2: 644 kg High pressure SG (216 Nm3) for hydrogenation For p-fuels and l-fuels 0.84 MWh(t) + 0.7 MWh (e)
