Biomass conversion to liquid fuels is an attractive process for production of drop-in fuels such as diesel and jet fuel. This process would help in reducing greenhouse gas emissions and decrease the need for using the fossil fuels. This is not a new process, but due to the chemical and economical challenges the process is not commercialized yet. The process is consisting of several steps where first the residual biomass needs to be collected and pretreated (drying, cutting). The pretreated biomass is then heated at very high temperature (up to 1000 °C) in process called gasification. During gasification process the biomass is converted to the gas mixture mainly consisting of H2 and CO which is called syngas. To be able to convert this syngas to valuable products (diesel and jet fuel) we use the process called Fischer-Tropsch synthesis, named after two German scientists. The process uses a catalyst which enables reaction to happen. Catalyst is an essential component of the process together with the specific process conditions (temperature, pressure, gas flow). During the process the catalyst can deactivate via different mechanisms. This is not desirable since this increases the cost of replacing the catalyst. The ideal would be if catalyst can operate at the same level for many years. During the Fischer-Tropsch synthesis one of the side products is water. This water deactivates the catalyst and reduce the efficiency of the process. To fix this issue, our project will implement the concept of removing the water using special materials and thus, prevent catalyst deactivation. In addition, diesel and jet fuel production will increase, and the cost would decrease. In this way the produced fuels will be competitive with the fossil fuels on the market. This might help in coming one step closer to the commercial Biomass to Liquid plant.

Level 1 – Academia - Synthesizing hybrid materials with dual functionalities will provide valuable insights into new area of advanced materials for similar processes, especially in the area of CO2 utilization, where water is an issue as well. Level 2 – Industry – The proposed BIOSEFT technology directly impact the renewable fuels for the transport market, as it targets the production of drop-in fuels such as diesel and jet fuel, which have direct application and proven positive environmental impact in terms of high performance and lower emission. In addition to generating new innovative knowledge, it is in the industrial use of this knowledge that innovation capacity is increased. Level 3 – Society and Environment – Accelerating the SDG; These impacts contribute to the achievement of Norwerian Policies, as well as many of the SDG 8, SDG 9, SDG 12, SDG 13 of Sustainable Development Goals – SDG.

This project envisions the development of a highly innovative technology that reshapes Fischer-Tropsch synthesis via sorption enhanced approach. This has great potential for increasing conversion efficiency, hydrocarbon yield and promote cost reduction. The BIOSEFT concept will be pushed through process intensification, innovative hybrid materials, and will be optimized by means of reactor modelling and process simulation. The BIOSEFT technology is highly innovative and has never been presented before. BIOSEFT will develop the application of tailored dynamically operated FT reactor where the water produced, as a by-product of the FT synthesis reaction, is systematically removed by solid water adsorbents (Step 1). The H2O-sorption active site is then regenerated in a separate step (Step 2), allowing for cyclic operation.
