摘要

Syngas with a H2/CO molar ratio less than 1 is contacted in a first stage with a Fe-comprising catalyst having Fischer-Tropsch as well as CO- shift activity; a H2/CO mixture optionally separated from the first stage product and having as such or after adjusting a H2/CO molar ratio of at least 1.5 is contacted in a second stage with a Co- or Ru- comprising Fischer-Tropsch catalyst. In this way the stability of the process is improved.
