Technology
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:
Raw material preparation – Gasification – Gas Cleaning – Fischer Tropsch Syntesis – Product Upgrade
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
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.
Gasification
The prepared woody biomass is sent into the gasification process and converted mainly to synthesis gas consisting of hydrogen and carbon monoxide.
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 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.
Product Upgrade
The paraffinic waxes are run through a process which converts them into usable jetfuel - SAF. (biodiesel/naphtha).
