    摘要： The present disclosure relates generally to compositions and processes for modifying Fischer-Tropsch product selectivity. In particular, the disclosure provides for a for converting a mixture of hydrogen and carbon monoxide gases to a product composition comprising alcohols and liquid hydrocarbons via Fischer-Tropsch synthesis in the presence of a supported cobalt-manganese Fischer-Tropsch synthesis catalyst, the process comprising: contacting the catalyst with a first gaseous feed comprising carbon monoxide and hydrogen for at least 12 hours to provide via Fischer-Tropsch synthesis a first product composition comprising C5+ hydrocarbons and alcohol; then contacting the catalyst with a first selectivity gaseous composition comprising at least 35 vol % H2 and a H2:CO molar ratio of at least 2; and then contacting the catalyst with a second gaseous feed comprising carbon monoxide and hydrogen to provide a second product composition comprising C5+ hydrocarbons, with a selectivity of no more than 5% for alcohols. Optionally, the catalyst selectivity to alcohols can be reversed by contacting the catalyst with a second selectivity gaseous composition comprising CO or a H2:CO molar ratio of at below 1.5.

    摘要： A process for converting a mixture of hydrogen and carbon monoxide gases to a composition comprising alcohols and liquid hydrocarbons by means of a Fischer-Tropsch synthesis reaction, said process comprising contacting a mixture of hydrogen and carbon monoxide gases, preferably in the form of synthesis gas mixture, with a supported Co—Mn Fischer-Tropsch synthesis catalyst, wherein: the support material of the supported Co—Mn Fischer-Tropsch synthesis catalyst comprises a material selected from titania, zinc oxide, zirconia, and ceria; the supported synthesis catalyst comprises at least 2.5 wt % of manganese, on an elemental basis, based on the total weight of the supported synthesis catalyst; the weight ratio of manganese to cobalt, on an elemental basis, is 0.2 or greater; the molar ratio of hydrogen to carbon monoxide is at least 1; and, the Fischer-Tropsch synthesis reaction is conducted at a pressure in the range of from 1.0 to 10.0 MPa absolute.

    摘要： The present invention generally relates to a Fischer-Tropsch process, in particular a Fischer-Tropsch process for converting a feed comprising a mixture of hydrogen and carbon monoxide gases, preferably in the form of a synthesis gas mixture, to hydrocarbons by contacting a cobalt-containing Fischer-Tropsch synthesis catalyst with a mixture of hydrogen and carbon monoxide in a reactor at a pressure of 4.0 MPa absolute or greater, wherein the process is initiated by a start-up procedure comprising the steps of: i) providing a feed comprising a mixture of hydrogen and carbon monoxide gases, preferably in the form of a synthesis gas mixture, to a reactor containing a cobalt-containing Fischer-Tropsch synthesis catalyst, wherein the pressure inside the reactor is 3.5 MPa absolute or below; and ii) maintaining the feed to the reactor, removing a product stream comprising hydrocarbons and maintaining the pressure inside the reactor at 3.5 MPa absolute or below for at least 15 hours, preferably for at least 50 hours.
