A catalyst for oxidative dehydrogenation (ODH) of ethane with an empirical formula MoVTeNbPdO produced using a process comprising impregnation of the Pd component on the surface of the catalyst following a calcination step using a Pd compound free of halogens. The resulting catalyst can be used in both diluted and undiluted ODH processes and shows higher than expected activity without any loss of selectivity.

The present invention provides a porous metal-containing carbon-based material that is stable at high temperatures under aqueous conditions. The porous metal-containing carbon-based materials are particularly useful in catalytic applications. Also provided, are methods for making and using porous shaped metal-carbon products prepared from these materials.

Disclosed is a catalyst for producing the olefin. The catalyst includes a support including alumina and a sub-support component, and a metal oxide impregnated on the support. The metal oxide includes anyone selected from an oxide of chromium, vanadium, manganese, iron, cobalt, molybdenum, copper, zinc, cerium and nickel; and the sub-support component includes anyone selected from zirconium, zinc and platinum.

In order to improve the lifetime of an SCR catalyst in the waste gas purification by means of the SCR process of waste gas of a biomass combustion plant, the catalyst comprises a sacrificial component selected from a zeolite and/or a clay mineral, in particular halloysite. During operation, catalyst poisons contained in the waste gas, in particular alkali metals, are absorbed by the sacrificial component so that catalytically active centers of the catalyst are not blocked by the catalyst poisons.
