Description
Anorganische Adsorbensmaterialien wie Molekularsiebe, Zeolithe usw. sind seit langem verwendet worden, um unerwünschte Bestand teile aus Fluiden (gasförmig und/oder flüssig) zu entfernen. Zeolithe wie Zeolith A und Zeolith X werden weit verbreitet bei Trocknungen und Gasbehandlungen verwendet.Inorganic adsorbent materials such as molecular sieves, zeolites etc. have long been used to inventory unwanted remove parts from fluids (gaseous and / or liquid). Zeolites such as Zeolite A and Zeolite X are widely used in Drying and gas treatments used.
In vielen Fällen wird das Adsorbensmaterial in Form eines freifließenden, teilchenförmigen Stoffes (z. B. Kügelchen) eingesetzt, der mit dem zu behandelnden Fluid in Kontakt gebracht wird.

The initial mixing resulted in one The temperature of the mixture increases to about 250 ° F. There were 495 lbs. Zeolite 3A (Grace Davison) and 55 lbs. Zeolite 13X (Grace Davison) activated and added to the mixer. During the following mixing, heat was generated by the mixing process, so that the temperature of the mixture is a maximum of about 310 ° F reached. The total mixing time was about 8 hours.
Die resultierende Zusammensetzung hatte ausgezeichnete adsorbie rende, rheologische und mechanische Eigenschaften. Die Wasser adsorption der Zusammensetzung ist in Fig. 1 gezeigt. Die Viskosität der Zusammensetzung als Funktion der Scherrate ist in Fig. 2 gezeigt.The resulting composition had excellent adsorbing, rheological and mechanical properties. The water adsorption of the composition is shown in Fig. 1. The viscosity of the composition as a function of the shear rate is shown in FIG. 2.
