Abstract: A method for the dehydrogenation of lower alkanes is disclosed. The method employs a chromium-alumina dehydrogenation catalyst with high chromium content supported on eta-alumina. The catalyst contains greater than 25 percent by weight chromium in the form of chromium (III) oxide, and exhibits extended stability over traditional alkane dehydrogenation catalysts.

Abstract: Rare earth element containing catalysts for dehydrogenating paraffins and the methods of making the catalysts are disclosed. A rare earth modified alumina support in eta-alumina form, theta-alumina form, or combinations thereof is impregnated with chromium-containing solution. The chromium-impregnated support is then subjected to calcination processes. The produced catalyst contains the rare earth element, chromium, and alumina. The crush strength of the produced catalyst is greater than 0.4 daN/mm.

Abstract: A method for producing methanol is disclosed. The method includes supplying a high oxygen content oxidant to combust hydrocarbons, in particular methane, and then using the resulting hot gases to heat natural gas so as to convert the natural gas to synthesis gas. The synthesis gas is used to produce methanol in a methanol synthesis reactor. At least some of the carbon dioxide from the hot gases is fed to the methanol synthesis reactor to make methanol.
