Definitions

  • the catalyst support can be in very different forms, for example as microfine dust with particle sizes in the range from 1 ⁇ m to 15 ⁇ m, as powder or granules with particle sizes in the range from 10 ⁇ m to 2.5 mm or in the form of fibers with diameters in the range from 1 ⁇ m to 100 ⁇ m.
  • a filter body extruded from catalyst carrier material is also conceivable, for example per, which preferably has the dimensions of a conventional tobacco smoke filter and can contain one or more longitudinal channels.
  • Mixed forms are also conceivable for the catalyst support, in particular mixed forms with components which are selected from the aforementioned forms.
  • the catalyst carrier can be sprinkled onto the filter material from a conveyor belt, or the catalyst carrier is mixed with the filter material in a drum.
  • Table 2 shows the carrier effect for each catalyst support in the first column, ie the percentage change in the content of the corresponding gas phase component in relation to the comparison measurement when the reactor is empty.
  • a minus sign means, as in example 1, a decrease.
  • the catalyst effect in the respective second column is the percentage change relative to the respective measurement with a catalyst carrier alone, that is to say without an active component, and accordingly gives Table 2 Percentage change in the content of selected gas phase components in cigarette mainstream smoke (reactor model, with Cambridge Reg filter) for various catalyst support materials; Carrier effect: without active component; Catalyst effect: with gold active component (additional effect)
  • Active components of a catalyst are applied to support materials (catalyst support) by precipitation, as explained in the following example for the preparation of a gold / “Siral 5” supported catalyst.
  • a mixture consisting of 900 mg of tetrachloroauric acid, 450 ml of distilled water and 6 g of urea was added with stirring.
  • the reaction mixture was heated to 70 ° C. and stirred at 70 ° C. for 5 hours.
  • Lyocell fibers with 25% carbon were made by an extrusion process, such as described in DE 100 53 359 AI, the grain size of the activated carbon was less than 12 microns.

Abstract

L'invention concerne un filtre à fumée de tabac servant à réduire les composants de fumée de tabac. Selon l'invention, un support de catalyseur, pourvu d'un composant actif et faisant de préférence partie intégrante d'un catalyseur complet, est placé dans ce filtre. Ce support de catalyseur est introduit dans le matériau filtrant lors de la production d'un tel filtre à fumée de tabac.
