Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania katalizatora tlenkowego, obejmujący sporządzenie zawiesiny nanocząstek prekursora fazy aktywnej z użyciem pola ultradźwiękowego, nanoszenie i immobilizowanie nanocząstek prekursora na nośnik, a następnie suszenie i kalcynowanie nośnika z immobilizowanym na nim prekursorem fazy aktywnej, charakteryzuje się tym, że odtleniony roztwór reakcyjny, zawierający rozpuszczone w wodzie sole chromu(III), poddaje się działaniu fal ultradźwiękowych o mocy od 70 - 100 W, częstotliwości 20 kHz, amplitudzie od 60 do 100%, w temperaturze od 10 do 60°C przez okres od 15 do 60 minut, przy czym w procesie sonikacji stosuje się nieciągłe w czasie oddziaływanie ultradźwięków na roztwór reakcyjny, gdzie poszczególne przedziały czasu oddziaływania ultradźwiękami trwają przez 2 do 5 min., zaś przerwy pomiędzy nimi wynoszą 20 do 50% a korzystnie 30 do 40% czasu oddziaływania ultradźwiękami. Ponadto do roztworu wprowadza się, najpóźniej w podczas sonikacji, alkohol o liczbie atomów węgla od 1 do 4, korzystnie etanol, w takiej ilości by jego stężenie wynosiło 1 - 3% obj., po czym otrzymaną w wyniku oddziaływania fal ultradźwiękowych nanosuspensję zawierającą jony Cr3+, Cr2+ oraz metaliczne formy chromu, nanosi się na nośnik.The subject of the application is a method for obtaining an oxide catalyst, comprising preparing a suspension of active phase precursor nanoparticles using an ultrasonic field, applying and immobilizing the precursor nanoparticles on a carrier, followed by drying and calcining the carrier with the active phase precursor immobilized on it, characterized in that the deoxygenated reaction solution , containing chromium (III) salts dissolved in water, is subjected to ultrasonic waves of 70 - 100 W, 20 kHz, amplitude from 60 to 100%, at a temperature from 10 to 60 ° C for a period of 15 to 60 minutes , in which the sonication process uses the discontinuous interaction of ultrasound on the reaction solution, where the individual intervals of ultrasound interaction last for 2 to 5 minutes, and the intervals between them are 20 to 50% and preferably 30 to 40% of the ultrasonic exposure time. In addition, alcohol with a carbon number of 1 to 4, preferably ethanol, is introduced into the solution at the latest during sonication, in such an amount that its concentration will be 1 - 3% by volume, after which the nanosuspension containing Cr3 + ions obtained as a result of the influence of ultrasonic waves. , Cr2 + and metallic forms of chromium are applied to the support.
