Abstract

Przedmiotem zgłoszenia jest sposób oczyszczania powietrza z lotnych związków organicznych (LZO), polegający na tym, że powietrze zanieczyszczone LZO podaje się do przepływowego reaktora fluidalnego, charakteryzujący się tym, że złoże fluidalne w reaktorze stanowi układ cenosfer o nienaruszonych, niepołamanych ściankach, o wielkości ziaren od 100 do 160 µm, pokrytych warstwą katalityczną nanocząstek platyny w matrycy z tlenku cynku (układ Pt/ZnO/Cenosfery), w którym zawartość nanocząstek platyny wynosi co najmniej 0,5%o w odniesieniu do masy początkowej cenosfer. Rozmiary nanocząstek platyny, osadzone na matrycy ZnO/cenosfery są nie większe niż 20 nm. Natomiast powietrze podgrzewa się do temperatury od 200°C do 500°C, a jego przepływ prowadzi się w zakresie prędkości liniowej strumienia gazowego 0,3 do 0,8 cm/s. Z kolei stosunek średnicy do wysokości złoża fluidalnego wynosi od 2/1 do 1/8.
