End products

​The end products from the Inbicon process include ethanol, C5 molasses and lignin. The second generation ethanol is sold by Statoil at 100 filling stations across Denmark. The lignin is used for DONG Energy's power production and C5 molasses is proved as a biogas booster at Danish biogas plants.

 

 

 

Ethanol

 

The ethanol produced is fully within the specifications of EN15376:2007 and complies with the standards set for bioethanol in the European Union: “Automotive petrol–Ethanol as a blending component for petrol – Requirements and test methods.”

Specification

Ethanol content + Higher saturated alcohols

98.7 %

Octane number

112

 

Usage
Bioethanol is a commercial blending component for gasoline.

C5 Molasses

During a hydrothermal pre-treatment of the straw, the hemicelluloses and alkali salts are washed out of the straw, and end up in the C5 molasses.

Specification

Sugar*

44% DM

Fat

0.4% DM

Protein

5% DM

Ash**

10% DM

Acetic acid

6% DM


*The sugars are primarily oligomers.
About 25% are monomers.

** 46% of the ash is minerals.

Usage
A high sugar content makes molasses a good commercial livestock feed. This product has more potential marketing possibilities such as further fermentation, as a booster biogas, alcohol or furfural production.

Lignin solid biofuel

 

Separated lignin is dried and pelletized. Our lignin has excellent binding properties and storage is less critical than for wood pellets due to partly hydrophobicity.

Further, grinding properties are much like coal.

Specification

Lower heating value

19-21 MJ/kg

Water

5-10%

Ash

7-12%

Density

680 kg/m3

Sulphur

0.07% - 0.13%


Usage
Lignin pellets from our process are a good coal replacement. In comparison with straw, their big advantage is reduced alkali metals content. So high temperature corrosion has not been an issue in our experience when burned in our boilers, suggesting great potential for lignin pellets to replace coal extensively in power stations.
