The disclosure provides catalyst materials in the form of annular solids with high mechanical integrity useful for water gas shift reactions and methods for using such catalyst materials, for example, for converting carbon monoxide and steam to carbon dioxide and hydrogen.

Shaped catalyst for sour gas shift reactions and methods for using them

A high efficiency catalyst for use in a catalytic partial oxidation process for the production of hydrogen or syngas gas from hydrocarbons is disclosed. The catalyst comprises rhenium in combination with a second metal selected from the group of rhenium to second metal of 25:1 to 1:1. the process comprises reacting a feed containing hydrocarbons with an oxygen source at a C/O ratio of about 0.9 to 1.1 in the presence of the catalyst, and wherein the gas hourly space velocity of the feed over the catalyst ranges from about 1,000 hrto about 2,000,000 hr. In the process, the catalyst is maintained as a temperature of from about 500&#xb0; C. to about 1,500&#xb0; C. as the feed makes contact with the catalyst.

Catalyst for production of hydrogen and synthesis gas

A promoted calcium-alumina supported reforming catalyst that is particularly useful for reforming reactions where low H/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.
