Biojet is basically technology neutral, but seeks to use what is at all times the "state of the art" of functioning processes to convert wood chips into fully qualified liquid biofuels (SAF - sustainable aviation fuel / alternatively biodiesel)

Typical process steps in a biodiesel production line:

As of today, there is no simple and proven way to convert wood-based raw material into fully qualified liquid biofuel. This means that the process must be composed of several steps that must play together in a continuous production process.

Process steps in the transformation

Råstoffmateriale av trær

Feedstock preparation

The raw material enters the factory as coarse wood chips and must be adapted in size and moisture content until it can be sent on to gasification.

Gassifiering av trær


The prepared woody biomass is sent into the gasification process and converted mainly to synthesis gas consisting of hydrogen and carbon monoxide.

Gassrensning av trær

Gas Cleaning

The synthesis gas must be cleaned of unwanted components which are mainly carbon dioxide, but also quite harmfull substances such as sulfur that came with the woody biomass. Biojet wants to utilize the biogenic carbon dioxide through collaboration with E-fuel producers or others.

Fischer-Tropsch syntese

Fischer-Tropsch Syntesis

The purified synthesis gas is sent into a Fischer-Tropsch reactor which converts the gas into paraffinic waxes consisting of different types of hydrocarbons.

The paraffinic waxes are run through a process which converts them into usable jetfuel - SAF. (biodiesel/naphtha).
