The conversion efficiency of CO2 in CO2-FTS over Fe-based catalysts is significantly enhanced by driving the conversion of the CO intermediate via the FTS reaction over a second kind of FT component, Co or Ru, without WGS activity.
A composite Na/Fe and SiO2-coated HZSM-5 catalyst system has been developed for the highly selective production of aromatics (93–95%), especially para-xylene, in the liquid phase and light olefins in the gas phase from CO2.
