    摘要： There is disclosed a catalyst support for selective gas phase reactions in a tubular fixed bed reactor comprising a metallic monolith having channels the walls of which are adapted to receive a catalytically active phase or an intermediate layer acting as a carrier for a catalytically active phase. The monoliths are coated with catalytically active material and loaded lengthwise into tubular reactors, the channels being parallel to the length of the reactors. The catalysts are particularly useful in the chlorination/oxychlorination of alkenes and alkanes, and the oxidation of alkenes. Compared with the use of conventional catalysts in pellet form or in the form of ceramic monoliths the catalysts of the invention offer greater yields and selectivity, the avoidance of hot spots, greater catalyst life and flexibility in use.

    摘要： The present invention provides a cylindrical hollow moulded catalyst having an outer diameter ranging from about 4 mm to about 7 mm, an inner diameter ranging from about 2 mm to about 2.8 mm, length ranging from about 6.1 mm to about 6.9 mm, and the ratio of the outer diameter to the inner diameter ranging from about 2 to about 2.5. The molded catalyst of the present invention is effective in the oxychlorination process, has a low resistance to flow, allows for good heat exchange with the wall of an industrial reactor and, with a suitable active phase based on copper and such additives as alkali metals, alkaline earth metals, group IIIB metals and lanthanides, is a good catalyst for fixed bed oxychlorination processes.

    摘要： In the oxychlorination of ethylene to produce 1,2-dichloroethane (EDC), in which ethylene, a chlorine source and an oxygen source are reacted in a fixed-bed oxychlorination reactor in the presence of a catalyst, a twin reactor system is used and the catalyst is a cupric chloride catalyst whose activity profile is arranged such that the reagent flow first comes into contact with a first layer of high activity catalyst, than a second layer of low activity catalyst and finally a third layer of high activity catalyst.
