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.The subject of the application is a method for purifying air from volatile organic compounds (VOCs), which involves feeding VOC-contaminated air into a fluidized bed reactor, characterized in that the fluidized bed in the reactor is a system of cenospheres with intact, unbroken walls, with a grain size of 100 to 160 µm, coated with a catalytic layer of platinum nanoparticles in a zinc oxide matrix (Pt/ZnO/Cenosphere system), wherein the platinum nanoparticle content is at least 0.5% based on the initial mass of the cenospheres. The size of the platinum nanoparticles deposited on the ZnO/cenosphere matrix is no larger than 20 nm. The air is heated to a temperature of 200°C to 500°C, and its flow is conducted within the linear gas stream velocity range of 0.3 to 0.8 cm/s. In turn, the ratio of the diameter to the height of the fluidized bed is from 2/1 to 1/8.
