C 07 c Zakłady Chemiczne "Oswiecim" *) Oswiecim, Poland Method for the preparation of a dehydration catalyst Additional patent to patent No. 45796 Patent valid since December 13, 1962 The subject of patent No. 45796 is a method of producing a dehydration catalyst from oxygen Iron activated with chromium and potassium, consisting in the use of a mineral called hematite cream. The iron oxide obtained by enrichment of the minerals by sludging is activated with chromium and potassium compounds, and a catalyst is obtained that is suitable for various dehydration reactions, especially for carrying out ethylbenzene. styrene.It turned out that the addition of magnesium compounds to the catalyst prepared in this way causes its further activation and improves its properties, especially it turned out to be The proprietor of the patent stated that the authors of the invention were Kazimierz Zielenski, Benedykt Kubica and Lech Soroczynski. of hematite obtained by slurring hematite cream, mixing and decanting into a paste to which the remaining activators are added as described in the patent specification No. 45796. The novel dehydrating catalyst thus obtained is suitable in particular for the preparation of isoprene from isoamylenes and of butadiene from butylenes, and furthermore exhibits excellent properties in many other dehydration reactions. 100 kg of a mineral called hematite cream was slurried to remove the deposit. The enriched product was composed of: Fe2O3 - 90%, SiO2 - 5%, Al2O3 - 4%, S - 0.3% in the amount of 692 kg. This product was mixed with 166 kg of magnesium oxide made into a thin paste. The whole was dried to a moisture content of 2%, 83 kg of potassium chromate, 43 kg of potassium carbonate and 16 kg of potassium hydroxide in concentrated aqueous solutions were added. After the mass was homogenized, sticks of 3 mm in diameter were pressed, dried and calcined at temperature. 500 ° C for 12 hours. Part of the obtained catalyst was operated at a temperature of about 620 ° C with a load of 500 l of butylenes per liter of catalyst per hour, giving an efficiency of about 85% of butadiene in terms of reacted butylenes. The part was used to dehydrogenate isoamylenes to isoprene at a temperature of 620 ° C with a load of 600 liters per liter of catalyst per hour. The yield was 83% of isoprene, based on the reacted isoamylenes. Regeneration was carried out by passing water vapor with air in such amounts that the temperature increase did not exceed 10 ° C. The periods between regenerations ranged from 10 - 4 hours depending on the working time (catalyst. PL
