标 题 :On-line synthesis and regeneration of a catalyst used in autothermal oxidation
发明人：BHARADWAJ SAMEER S; MAJ JOSEPH J; SIDDALL JONATHAN H
权利人:DOW GLOBAL TECHNOLOGIES INC
摘要:An on-line method of synthesizing or regenerating catalysts for autothermal oxidation processes, specifically, the oxidation of paraffinic hydrocarbons, for example, ethane, propane, and naphtha, to olefins, for example, ethylene and propylene. The catalyst comprises a Group 8B metal, for example, a platinum group metal and, optionally, a promoter, such as tin, antimony, or copper, on a support, preferably a monolith support. On-line synthesis or regeneration involves co-feeding a volatile Group 8B metal compound and/or a volatile promoter compound with the paraffinic hydrocarbon and oxygen into the oxidation reactor under ignition or autothermal conditions.
