Parameter Study with Sulfidized Molybdenum Catalyst for Mixed Alcohol Synthesis with Biomass-Derived Synthesis Gas
Weber, G., Rauch, R., Hofbauer, H.
In the Güssing CHP (combined heat and power) plant, dual fluidized bed (DFB) gasification technology is used to provide a high quality biomass-derived synthesis gas with a high content of hydrogen and carbon monoxide. The synthesis gas is highly suitable for synthesis gas applications like Fischer-Tropsch (FT) synthesis, mixed alcohol synthesis (MAS) and hydrogen production. Since 2011, a pilot plant for the production of mixed alcohols from the synthesis gas has beenin operation. A steam reforming unit and a glycol scrubber are utilized to clean the synthesis gas. The gas is further compressed and then conducted in the MA synthesis reactor, which is carried out as a fixed bed. Afterwards, the alcohols are separated from the gas stream in a condensation unit. The tail gas is expanded back to atmospheric pressure and utilized in the CHP plant. Two batches of alkali-doped molybdenum sulfided catalysts (MoS2) were successfully tested at the pilot installation. Parameter variations were carried out, particularly focusing onvariations in the reaction temperature and the space velocity. The reaction temperature hada profound influence on CO conversion, the formation of alcohols and various side reactions.
