    摘要: A promoted calcium-alumina supported reforming catalyst that is particularly useful for reforming reactions where low H2/CO ratio synthesis gas, such as less than 2.3 is generated directly is disclosed. The catalyst comprises from about 25 wt % to about 98 wt % alumina, from about 0.5 wt % to about 35 wt % calcium oxide, from about 0.01 wt % to about 35 wt % of a promoter, and from about 0.05 wt % to about 30 wt % of an active metal. The promoter is selected from the group consisting of titanium, zirconium, yttrium, niobium, elements of the lanthanum-series, such as, without limitation, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, ytterbium, and combinations thereof. The active metal is selected from the group consisting of nickel, cobalt, rhodium, ruthenium, palladium, platinum, iridium and combinations thereof as active metal, wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.

    摘要: The Fischer-Tropsch catalyst of the present invention is a transition metal-based catalyst having a high surface area, a smooth, homogeneous surface morphology, an essentially uniform distribution of cobalt throughout the support, and a small metal crystallite size. In a first embodiment, the catalyst has a surface area of from about 100 m2/g to about 250 m2/g; an essentially smooth, homogeneous surface morphology; an essentially uniform distribution of metal throughout an essentially inert support; and a metal oxide crystallite size of from about 40 Å to about 200 Å. In a second embodiment, the Fischer-Tropsch catalyst is a cobalt-based catalyst with a first precious metal promoter and a second metal promoter on an aluminum oxide support, the catalyst having from about 5 wt % to about 60 wt % cobalt; from about 0.0001 wt % to about 1 wt % of the first promoter, and from about 0.01 wt % to about 5 wt % of the second promoter. The high surface area transition metal-based catalysts of the present invention are prepared in a non-acidic solution at a pH greater than about 7.0, and starting with a non-acidic transition metal complex. The resulting product is a catalyst with a uniform distribution of metal throughout the catalyst particles, with a smooth and homogeneous surface morphology, and with slow crystallite growth upon heating.
