A method for controllably producing a hematite-containing Fischer-Tropsch catalyst by combining an iron nitrate solution with a precipitating agent solution at a precipitating temperature and over a precipitation time to form a precipitate comprising iron phases; holding the precipitate from at a hold temperature for a hold time to provide a hematite containing precipitate; and washing the hematite containing precipitate via contact with a wash solution and filtering, to provide a washed hematite containing catalyst. The method may further comprise promoting the washed hematite containing catalyst with a chemical promoter; spray drying the promoted hematite containing catalyst; and calcining the spray dried hematite containing catalyst to provide a calcined hematite-containing Fischer-Tropsch catalyst.

Catalyst for low temperature slurry bed Fischer-Tropsch synthesis

The present invention provides methods and compositions for the chemical conversion of syngas to alcohols. The invention includes catalyst compositions, methods of making the catalysts, and methods of using the catalysts including techniques to maintain catalyst stability. Certain embodiments teach compositions for catalyzing the conversion of syngas into products comprising at least one C-Calcohol, such as ethanol. These compositions generally include cobalt, molybdenum, and sulfur, and avoid metal carbides both initially and during reactor operation.

An iron-based Fischer-Tropsch catalyst comprising magnetite and characterized by integrable X-ray diffraction reflections corresponding to (311), (511), (440), and (400), such that the relative intensity of the (400) reflection to the (300) reflection is less than about 39%. A method of preparing an activated iron-based Fischer-Tropsch catalyst by providing a precipitated catalyst comprising oxides including at least iron oxide; and activating the precipitated catalyst to provide the activated iron-based Fischer-Tropsch catalyst, wherein activating the precipitated catalyst comprises exposing the precipitated catalyst to an activation gas and increasing the temperature from a first temperature to a second temperature at a ramp rate, whereby the ratio of the intensity of the (400) reflection of the activated iron-based Fischer-Tropsch catalyst to the intensity of the (311) reflection thereof is less than 38%.

Iron-based fischer-tropsch catalyst

This invention provides a method for producing ethanol and 2-propanol from syngas, the method comprising: (a) converting syngas into methanol using a methanol-synthesis catalyst; (b) converting methanol into ethylene and propylene using a methanol-to-olefins catalyst; and (c) hydrating ethylene into ethanol and propylene into 2-propanol. As taught herein, the combined yield of the ethanol and the 2-propanol from biomass can be at least 100 gallons per dry ton biomass. In certain embodiments, the yield of ethanol is at least 100 gallons per dry ton biomass. In some embodiments, the yield of 2-propanol is at least 50 gallons per dry ton biomass.

Cobalt-molybdenum sulfide catalyst materials and methods for ethanol production from syngas

This invention improves prior methods of making cobalt-molybdenum-sulfide catalysts for alcohol production from syngas. In one aspect, improved methods are provided for making preferred cobalt-molybdenum-sulfide compositions. In another aspect, processes utilizing these catalysts for producing at least one C-Calcohol, such as ethanol, from syngas are described.

Methods of making improved cobalt-molybdenum-sulfide catalyst compositions for higher alcohol synthesis

The invention herein provides methods of activating a catalyst composition. These methods include annealing a catalyst with an inert gas, under effective conditions, and then contacting the annealed catalyst with syngas to produce an activated catalyst. These steps can also be reversed. The activated catalysts can be employed to convert syngas into products, such as alcohols, with improved selectivities and yields.

Methods for improving syngas-to-alcohol catalyst activity and selectivity

The present invention provides methods of intercalating a catalyst promoter to form a catalyst composition suitable for converting syngas into alcohols, such as ethanol. Effective conditions for promoter intercalation are provided herein. This invention also provides novel compositions that can be characterized by interplanar spacings of the promoter within the catalyst composition.
