Abstract
Przedmiotem zgłoszenia jest sposób termokatalitycznego utleniania i odsiarczania związków organicznych zawierających siarkę, polegający na poddaniu ich w stanie gazowym całkowitemu utlenieniu powietrzem w reaktorze przepływowym, w obecności katalizatora kontaktowego reakcji utleniania, przy stosunku objętościowego natężenia przepływu powietrza użytego w procesie do objętościowego natężenia przepływu powietrza teoretycznie niezbędnego do całkowitego utlenienia substratu równym co najmniej 1,1, przy stosunku objętościowego natężenia przepływu mieszaniny reakcyjnej do objętości katalizatora równym 360 — 360000 h<sup>-1</sup> i czasie kontaktu z katalizatorem 0,01 — 10 s, a po procesie utleniania na usunięciu siarki zaadsorbowanej na katalizatorze w postaci jej tlenków oraz usunięciu produktu całkowitego utlenienia związku organicznego do środowiska, po zneutralizowaniu jego kwaśnych składników, charakteryzuje się tym, że stosuje się katalizator zawierający metal szlachetny osadzony na nośniku zawierającym metal przejściowy, zawierający co najmniej 0,1% wagowych metalu szlachetnego. Proces utleniania prowadzi się w temperaturze 300°C — 550°C.
