Higher Alcohols

Carbon2Chem® subproject L-IV

Work in phase 1

In subproject L4 "Higher alcohols" Fraunhofer UMSICHT supported the consortium in the testing of heterogeneous catalysts. Up to seven different catalysts were tested and evaluated in a parallel reactor under exactly the same reaction conditions. In this way, a fast screening of the prepared catalysts was possible and promising samples could be selected for more in-depth investigations. In two further laboratory test plants it was possible to add alcohols – especially methanol – to the feed gas stream in addition to the synthesis gas components CO, CO2 and H2. Besides intensive measurements of gas composition and reaction conditions, methanol homologation could be explicitly investigated at these plants and the possibility of MeOH-circulation could be evaluated. Furthermore, conclusions on the macrokinetics of the reaction could be drawn.

Aims in phase 2

In the second project term of L-IV "Higher Alcohols", a catalytic overall process for the direct conversion of upgraded coupled gas to short-chain alcohols, olefins and synthetic fuels is to be developed and brought to demonstration maturity. Perspectives and options for a market-driven processing of the resulting product mixture will be worked out.
