The Fischer-Tropsch synthesis is an important process to convert coal, natural gas and biomass to a variety of hydrocarbon products and oxygenates of different chain length.
In this modified Fischer-Tropsch process valuable nitrogen or phosphorous containing products of varying chain length are produced via co-feeding of suitable gases such as ammonia. These nitrogen-containing products include amines but also nitriles, amides and formamides. Amines and nitriles are important base chemicals and they are typically produced from oxygenates precursors which themselves are derived from olefins. This process therefore eliminates the use of a two-step process. Similarly phosphorous containing compounds can be produced. Moreover, the formation of oxygenates including carboxylic acids which are undesired products of the synthesis can be fully suppressed with the modified process. Notably this can be achieved with no or tolerable loss of catalyst activity.
