    摘要: Process for preparing polyolefins having high molecular weights in the presence of a catalyst comprising an organic transition metal compound in a gas-phase fluidized-bed reactor, where the polyolefins prepared have a melt flow rate at 2.16 kg and 190° C. in accordance with ISO 1133 of less than 4 g/10 min. According to the present invention, a start-up phase during which a polyolefin having an increased melt flow rate of above 4 g/10 min is produced for a transitional period is provided. In this way, trouble-free start-up of the reactor is ensured even in the case of polymer products having a high molecular weight and a melt flow rate below 4 g/10 min and even when using catalysts based on organic transition metal compounds, in particular metallocene catalysts.

    摘要: In a method of removing volatile oxidizable compounds from particles present in a container, a gas stream is continuously introduced into the container, the gas stream takes up the oxidizable compound from the particles in the container and a gas stream laden with the oxidizable compound is discharged from the container. In the method of the present invention, oxygen is added to the gas stream which has been discharged and the oxidizable compound present in the discharged gas stream is subsequently at least partly catalytically oxidized by means of the oxygen and this oxidized gas stream forms at least part of the gas stream introduced, so that the gas stream is circulated. This makes safe and inexpensive removal of the oxidizable compounds from the particles possible.

    摘要: In EUV lithography apparatuses (10), it is proposed, in order to lengthen the lifetime of contamination-sensitive components, to arrange them in a protection module. The protection module comprises a housing (23-29) having at least one opening (37-47), in which at least one component (13a, 13b, 15, 16, 18, 19) is arranged and at which one or more gas feeds (30-36) are provided in order to introduce a gas flow into the housing (23-29), which emerges through the at least one opening (37-47). In order to effectively prevent contaminating substances from penetrating into the protection module, a light source (48-56) is arranged at the at least one opening (37-47), which light source illuminates the opening (37-47) with one or more wavelengths by which the contaminating substances can be dissociated before they penetrate through the opening (37-47).
