Photooxidation of sub-parts-per-million toluene and formaldehyde levels on titania using a glass-plate reactor
Article Abstract:
A titania-coated glass plate reactor was utilized to determine the kinetics of toluene and formaldehyde photooxidation in various sub-parts-per-million (ppmv) contaminant levels, humidity levels and ultraviolet (UV) intensities. The oxidation rates of toluene and formaldehyde were affected by high levels of temperature and humidity in the plate reactor. Formaldehyde also exhibited high reactivity levels compared to toluene during exposure to intense UV radiations.

TiO2 photocatalysis for indoor air applications: effects of humidity and trace contaminant levels on the oxidation rates of formaldehyde, toluene, and 1,3-butadiene
Article Abstract:
A study was conducted to analyze the effects of humidity and trace contaminant levels on the oxidation rates of formaldehyde, toluene and 1,3-butadiene. UV intensities from mercury fluorescent lamps of each element were measured and compared. The results showed that oxidation rates of the contaminants increased in the presence of water vapor. This suggests that there is a directly proportional relationship between contaminant concentration and humidity levels.

Heterogeneous oxidation of acetic acid in supercritical water
Article Abstract:
The kinetics of acetic acid supercritical water oxidation (SCWO) were analyzed batch SCWO reactor systems. The SCWO of acetic acid was characterized by a heterogeneous mechanism under constant surface effect in the bioreactor. Furthermore, the rate of acetic acid conversion also increased with the levels of oxygen in the bioreactor system. However, bioreactor surface effect greatly affected the heterogeneity of acetic acid SCWO.
