    摘要: A process is disclosed for the hydrogenation of carbon monoxide. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst system in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream, preferably comprising hydrocarbons. In accordance with this invention the catalyst system used in the process includes at least one catalytic material for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium), preferably comprising cobalt, and a support comprising aluminum borate. The catalyst system can be prepared by impregnating alumina with a boron-containing composition to form an aluminum borate support and applying a Fischer-Tropsch catalytically active material to the aluminum borate to form a supported catalyst system.

    摘要: Methods and apparatus for improving the efficiency and effectiveness of in situ reduction of a Fischer-Tropsch catalyst slurry. The preferred embodiments of the present invention are characterized by a system that utilizes a co-feed of carbon monoxide along with the reducing gas into a reduction vessel maintained at an elevated temperature. As the metal oxide reduces to the active Fischer-Tropsch metal, the carbon monoxide acts as a poison to hydrogenolysis and reduces the loss of liquid from the slurry and the production of methane. The carbon monoxide is generally in parts-per-million quantities and will achieve the desired results in quantities less than 5,000 ppm, preferably less than 2,000 ppm.

    摘要: A process for reducing C2-C9 olefin formation by recycling them to a Fischer-Tropsch hydrocarbon synthesis process and promoting recycled olefins chain growth comprises contacting a gas feed comprising a mixture of H2 and CO with a catalyst in a reactor system at conditions effective to produce a hydrocarbon product stream including C2-C9 olefins, separating a C2-C9 olefins-rich stream from the hydrocarbon product stream to form a light olefin recycle stream and recycling the light olefin recycle stream to the reactor system at a point in the reactor system where the H2:CO ratio is low relative to the H2:CO ratio in the rest of the reactor system. Depending on whether the initial H2:CO ratio is greater or less than the usage ratio of the selected catalyst, the recycled olefins can be returned to the system up- or downstream of the reactor system.

    摘要: The present invention is generally related towards methods for preparing and using a more stable synthesis catalysts. In particular, the present invention is directed towards treating synthesis catalysts with low levels of oxygen to deactivate the smaller more unstable metal crystallites present in the catalyst matrix. The process can be carried out either prior to and/or simultaneously with the synthesis reaction.
