Abstract: A technology for producing synthesis gas from crude gas from various gasification processes for solid or liquid fuels. To limit the temperatures in a subsequent strongly exothermic CO shift reaction to adjust the H2/CO ratio, the crude gas which has been freed of dust flows through two shift reactors arranged in series. The first reactor has a specific reaction-kinetically limited catalyst and the second reactor has a conventional sour gas catalyst. The specific catalyst used in the first reactor limits the exothermic shift reaction to such an extent that the reaction temperatures in the first and second reactors remain so low to avoid thermal damage to the catalysts even without introduction of external steam, and the desired gas composition is achieved.

Abstract: A process for removing one or more of arsenic and other contaminants from a synthetic gas feedstock comprising a sulfur compound. The synthetic gas feedstock is contacted with a composition having an active material. The active material includes one or more elements having an electronegativity from 1.6 to 2.0 on the Pauling scale. At least a portion of the active material is a sulfide phase.

Abstract: A strontium-doped, calcium-alumina nickel supported reforming catalyst is useful for reforming reactions when it is desired to generate a low H2/CO ratio synthesis gas and to reduce coking. The catalyst can generate a synthesis gas having a H2/CO ratio of less than about 2.3. The catalyst includes alumina, from about 0.3 wt. % to about 35 wt. % of calcium oxide, from about 0.1 wl % to about 35 wt. % of a strontium promoter, and about 0.5 wt. % to about 30 wt. % nickel. The support is prepared by a method wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.

Abstract: 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.
