专利号:US-6624116-B1 优先权日:1998-09-03 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.

专利号:US-6555640-B1 优先权日:1999-09-28 标 题:Process for producing metal-containing resin and composition thereof 发明人:ITO KEI; KAWAMURA CHIKARA 权利人:KANSAI PAINT CO LTD 摘要:Process that is capable of synthesizing a metal-containing resin having a good antifouling property in a short period of time without having such problems associated with the synthesis as gelation. The process for producing a metal-containing resin by conducting a copolymerization reaction of a monomer mixture (A) comprising 1 to 50% by weight of a carboxyl group-containing polymerizable unsaturated monomer (a) and 50 to 99% by weight of other polymerizable unsaturated monomer (b) in an organic solvent in the presence of water and an oxide or hydroxide of a metal having a valency of at least 2, wherein the amount of water is 1 to 30 parts by weight based on 100 parts by weight of the monomer mixture (A), and the formation of a metal carboxylate bond occurs together with the copolymerization of the monomer mixture (A); and an antifouling coating composition containing, as an active constituent, a metal-containing resin obtained by the production process.
