Selectivity of the modified Fischer-Tropsch syntheses

A study was made on selectivity of modified syntheses of Fisher-Tropsh (MSFT), performed with the use of ammonia, dimethylamine and piperidine, on reduced iron promoted melt catalysts. On the base of data received it was possible to formulate the general principles in attainment of limiting selectivity in MSFT. The composition of iron catalysts and conditions of syntheses conduction must provide the most concentration in synthesis products of alcohols, aldehydes and ketones and also quantitative hydroamination of their predecessors (oxygen-containing intermediates) and/or carbonyl compounds to alkylamines.
