Bio Fuel Laboratory

360 picture of the lab


The Bio Fuel Laboratory facilitates members and collaborating partners of the Biomass Programme. It offers state-of-the-art experimental facilities to test processes and analyze feeds and products.

Bio Fuel Team


The Bio Fuel Laboratory performs production, tests and chemical analysis of Bio Fuel and other fuels. It consists of 2 laboratories and a HTL production facility:

  • HTL facility - 20 kg/h feed plant with processing conditions up to 450°C/350 bar
  • Bio Fuel Production & Test Lab - equipment for lab scale production and testing fuels e.g. hydrotreater, lab scale HTL set up, catalyst activation set-up
  • Bio Fuel Analyses Lab - analytical instruments facilitating analysis of oils, water samples and solid substances i.a. SimDist, GC/MS, GC, CHNS/O etc.

Bio Fuel Laboratory

Special equipment

Continuous Hydrothermal Liquefaction (HTL) facility CBS

The Continuous Bench Scale 1 (CBS1) HTL facility has a capacity of 20-30 kg/h feed. Processing conditions are up to 500 deg C, 350 bar. The plant is equipped with state-of-the-art controls, high resolution instrumentation, online gas sampling, gravity-assisted product separation and oil demineralization. A wide range of input biomasses are possible (wood, manure, algae etc).

Bio Fuel Production & Test Lab

The Bio Fuel Production & Test Lab offers the possibility of testing performance of Bio Fuels and other fuels in lab/pilot plant scale.
The lab consists of a variety of instruments - hydrotreater, lab scale HTL set up, catalyst activation set-up, etc.

Production/TEST equipmenT


Our continuous hydrotreater involves a pumping system for bio-oil, two tubular reactors (to be run in series or parallel) and a product separation section. It is fully automated and can be controlled through LabView® interface. A bio-oil throughput of 300 mL/h can be achieved.

Distillation System

Buchi Rotavapor R-210; a pressure and temperature controlled vacuum distillation system. Packed column vacuum distillation column, 15 theoretical plates, 2 l boiling flask capacity.

Activation SeT-UP

The Activation Set-up is constructed to reduce and activate catalysts for Hydrotreater experiments.

Lab scale Reactors - 5-15 mL

Micro batch reactor systems for parametric studies. Very rapid heating up to max 500°C, quench cooling. Online pressure and external temperature sampling.

Lab scale Reactors - 400 mL system

The 400 ml autoclave equipped with stirring, a cooling coil, a heater and an external high pressure injection pot. Can operate in batch mode or injection, when desired reaction conditions have been reached. The system is rated for 350 bar/500°C.

Lab scale Reactors - 1 L system

The 1 l system is a semi-continuous system consisting of a 1 l autoclave equipped with a high pressure injection pot and a batch disposal system. The disposal system consists of a flash-drum and condenser which enables repeatable experiments without disassembling the system. The system is rated for 350 bar/500°C.

Bio Fuel Analysis Lab

Bio Fuel Analysis Lab possesses a variety of Analytical instruments facilitating analysis of oils, water samples and solid substances. The equipment constitutes i.a. SimDist, GC/MS, GC, CHNS/O elemental analyzer, FT-IR, Karl Fischer titration unit, etc.

Bio Fuel Laboratory

Analysis equipment          


SimDist is constituted of a multi-dimensional GC/GCMS system performing separations using two columns with different chromatographic selectivity.

GC Gas Chromatography (GC Gas)

For Gas sample analysis the lab has a GC unit available. The system is used for the identification and quantification of components in gas from HTL plant and micro reactors.

GC/MS - Gas Chromatography/Mass Spectrometry (GC/MS)

For sample analysis the lab has a GC/MS unit available. The system is used for the identification and quantification of components in feedstock and products.
