Synthesis of alternative fuels and platform molecules over nanoreactors – NANO4FuT

Submission summary

The demand for ultra-clean alternative fuels and chemicals produced from biomass has been rapidly growing around the world. The fundamental target of this research project deals with the design of novel nanoreactor systems with encapsulated metal nanoparticles and processes for the sustainable direct synthesis of fuels and chemicals from synthesis gas (CO + nH2) generated via gasification of biomass. The main method for biosyngas valorization is Fischer-Tropsch synthesis (FT) which converts it into wide range of hydrocarbons. Two types of catalysts are usually used for Fischer-Tropsch (FT) synthesis – cobalt for low temperature FT synthesis to produce linear paraffins and iron for high temperature FT synthesis for the production of olefins. Very broad chain length distribution (C1-C60) which follows Anderson-Schulz-Flory (ASF) statistics is the main problem of these processes.
Our approach here is directed on the development of smart catalysts on the basis of nanoreactors with encapsulated metal in order to sterically restrict the growth of the hydrocarbons in the limited volume for the direct selective synthesis of valuable products like diesel and olefins. The traditional way of the preparation of nanoreactors involves application of organic and inorganic matrixes with the diameter of the shell in the range 30 to 150 nm with mostly effect on the stability of metal nanoparticles. This project is focused on controlled synthesis of nanosized (5-15 nm) yolk-shell systems with encapsulated Co and Fe metal nanoparticles to control the reaction selectivity and chain length of the FT products. New methodologies on the basis of microemulsion and gas phase deposition will be used for the synthesis of nanoreactors with controlled parameters like size, porosity and thickness of the shell.
This strategy will affect all parameters of the catalytic processes like the activity, selectivity and stability due to the high dispersion of metal, low interaction with support, effective use of the shell, restriction of the growth of hydrocarbons, effective interaction with promoters and suppression of the catalyst sintering. New 3D structured nanoreactor materials are expected to provide perspective catalysts for industrial implementation.
