Torrefaction
Thermal treatment at a temperature of 200 to 300C,
at near atmospheric pressure and in the absence of
oxygen.
Water, volatile organic compounds liberates from
cellulose and lignin. Volatiles may be combusted to
generate process heat
About 90% of the energy is retained and about 70% of
the mass weight

Fast pyrolysis
Superior bio-oil yields versus other pyrolysis
processes. Yield up to 70% on energy basis.
Non-condensable gases (~15%) can be
combusted to provide energy
Char (10-15%) is similar to charcoal and has a
high heating value (28-30 GJ/tonne)
Flexible with respect to feedstock type

RENERGI Innovation project
Project owner Norske Skog ASA
Project management PFI
Objective:
Develop and/or modify technology for producing bio-oil qualities from wood
logging residues suitable for replacing fossil heating oils and for further
upgrading to transportation fuel.
Find an alternative sustainable method for ash removal which leaves minimum
inorganic ash in the bio-oil
Develop feed mix protocols for producing single phase bio-oil
Establish a practical guideline for bio-oil combustion and evaluate the need for
additives/ fossil fuel support

Pyrolysis oil can be used to replace fossil fuels used in
stationary gas turbines and boilers. Commercialization
depends on the ability to provide a fuel of acceptable
quality to an end user at a competitive price.
Crude pyrolysis oil has been used with success in
industrial boilers and an American test method
specification has been released to guide industrial burners
equipped to handle pyrolysis oils.
Critical quality demands:
Homogenityand stability,
Solids (< 0.05%)
and ash content (< 0.03%)
,
Water content
Flash point
In engines, crude pyrolysis oil is unsuitable for direct use
and needs some upgrading.

New fractionation concept for co-
production of :
Solids and ash freepyrolysis oil
Low ash content is critical to reach
particle emission demands when
using pyrolysis as replacement for
fossil heating oils
Low ash content is critical for
pyrolysis oil upgrading
Viscous lignin-enrichedpyrolysis oil
Lignin-enriched pyrolysis oil is a
favorable platform for producing
functional chemicals like bio-binders
Charcoal
High energy density (28-30 GJ/t)
Can be used as charcoal in boilers

Torrefaction and fast pyrolysis brings efficient energy densification of biomass
which improves the competitiveness of biomass as an energy carrier
Both fast pyrolysis plants and torrefaction plants should be co-located and
process integrated with other process industry so that the energy produces
from combusting byproducts (volatiles, char) can be exploited to full extent
Torrefied pellets is a nearly commercialized technology. Knowhow is essential
to obtain high bulk energy density, good pellet durability and safe processing
and handling related to fire risk.
Crude fast pyrolysis bio-oil can replace fossil fuel in boilers. Through
upgrading, higher value-creation can be obtained by producing pyrolysis
liquids which are suitable for diesel engines and/or compatible with oil
refineries.
A newprocess for co-production of “solids free” pyrolysis oil, a viscous
lignin-enriched pyrolysis oil fraction and charcoal has been developed. The
lignin-enriched pyrolysis oil is a favourable platform for producing functional
chemicals like bio-adhesives.
