Abstract: The invention provides a method for controlling a selectivity profile of products of a Fischer-Tropsch synthesis process, wherein a catalyst promoter, either dissolved in solution or in a powdered form, is directly injected into the reactor medium, typically into the reactor feedstream. The Fischer-Tropsch process is typically a High Temperature Fischer Tropsch (HTFT) process, and a typical chemical promoter for the HTFT process is potassium. By adding or doping the reaction medium with the catalyst promoter during the synthesis process, the selectivity profile of olefins and paraffins in the product stream is significantly changed, with more olefins being formed whilst the level of paraffins is reduced, and typically the level of olefins in the C2-C4 range is increased. The catalyst promoter may form part of a promoter-carrying compound, for example, potassium carbonate.

Abstract: Methods for converting of syngas to higher molecular weight products using Fischer-Tropsch synthesis, and methods for optimizing the catalyst systems in the synthesis, are disclosed. In one embodiment, the methods use cobalt/ruthenium Fischer-Tropsch catalysts in combination with an olefin isomerization catalyst, which isomerizes double bonds in C4+ olefins as they are formed. In another embodiment, the methods use Fischer-Tropsch catalysts that may or may not be cobalt/ruthenium catalysts, in combination with olefin isomerization catalysts which are acidic enough to isomerize the C4+ olefins but not too acidic to cause rapid coking. A benefit of using the relatively less acidic zeolites is that the ratio of iso-paraffins to aromatics is increased relative to when more acidic zeolites are used. Also, the relatively less acidic zeolites do not coke as readily as the relatively more acidic zeolites.
