Gaseous ozone decomposition over high silica zeolitic frameworks
(2018-09)For several decades, it has been known that ozone emissions are harmful to humans, plants, and animals. Heterogeneous catalytic decomposition is an efficient process for removing ozone from air. This study examines the ... -
Heterogeneous catalytic ozonation of benzothiazole aqueous solution promoted by volcanic sand
(2008-05-30)This paper presents experimental results on the catalytic effect of volcanic sands on benzothiazole ozonation. Experiments were assessed at laboratory scale, in a differential circular flow reactor composed of a volcanic ... -
New insight of the influence of acidic surface sites of zeolite on the ability to remove gaseous ozone using operando DRIFTS studies
(2020-01-01)Recently, natural zeolites have started to be used as alternative materials for ozone abatement from working environments. In this study, a surface response methodology based on a D-Optimal design is applied to develop ... -
Oxidative regeneration of toluene-saturated natural zeolite by gaseous ozone: The influence of zeolite chemical surface characteristics
(2014)In this study, the effect of zeolite chemical surface characteristics on the oxidative regeneration of toluene saturated-zeolite samples is investigated. A Chilean natural zeolite (53% clinoptilolite, 40% mordenite and 7% ... -
Ozonation of pentylacetate contaminated waters from textile care industry
(2013)In this article the use of ozone for the treatment of pentylacetate contaminated waters is evaluated. Pentylacetate has started to be used in the drycleaning process as a new solvent due to its economic benefits. ... -
Role of Lewis acid sites of ZSM-5 zeolite on gaseous ozone abatement
(2013)In this work, chemical interactions between ozone and zeolite surface active sites are studied in order to propose a process for gaseous ozone removal. Synthetic ZSM-5 zeolites with three different Si/Al2 ratios and similar ...
