APPLICATION OF CHROME SOURCE IN COMBINATION WITH PRECIPITATED CATALYST IN FISCHER-TROPSCH REACTION Russian patent published in 2010 - IPC C10G2/00 C07C1/04 B01J23/652 B01J37/03 

FIELD: chemistry.

SUBSTANCE: invention concerns application of chrome source as catalyst activator in combination with precipitated iron catalyst in high-temperature Fischer-Tropsch process for transformation of CO and H₂ reagents into reaction products in the form of hydrocarbons and possible hydrocarbon oxygenates by contacting CO and H₂ with chrome source combined with precipitated iron catalyst in the course of two-phase high-temperature Fischer-Tropsch reaction. Reaction is performed in reactor with fluidised layer, reactants and reaction products are in gas phase, and catalyst is in solid phase. Chrome source concentration in precipitated iron catalyst comprises 0.3-1 g of chrome per 100 g of iron. Beside chrome source, precipitated iron catalyst includes at least one additional catalyst activator. Also invention claims two-phase high-temperature Fischer-Tropsch process.

EFFECT: enhanced catalyst activity, reduced organic acid formation and methane concentration.
