Ozone Decomposition and Acetone Oxidation on Manganese Oxide Catalysts
… a typical volatile organic compound (VOC), and ozone decomposition. This topic is of great value because of environmental concerns of the elimination of the harmful VOCs and ozone. Manganese oxide was chosen because it is a well-known complete oxidation catalyst for VOCs and also an active …

Structure and Ozone Decomposition Reactivity of Supported Manganese Oxide Catalysts
… were used to study the effect of support on ozone decomposition kinetics. X-ray diffraction (XRD), in-situ laser Raman spectroscopy, temperature programmed oxygen desorption, surface area measurements, extended and near edge x-ray absorption fine structure (EXAFS and NEXAFS) showed that the …

Kinetics and Mechanism of Ozone Decomposition and Oxidation of Ethanol on Manganese Oxide Catalysts
… of catalytic reactions. Two cases involving ozone reactions on manganese oxide catalysts were treated. Manganese oxide was chosen because it is the most active of the transition metal oxides for ozone decomposition and because it is a well-known catalyst for complete oxidation reactions. The …

Kinetic and mass transfer studies of ozone degradation of organics in liquid/gas-ozone and liquid/solid-ozone systems.
… of mass transfer and kinetic parameters of ozone reactions with four organic compounds from different families, namely reactive dye RO16, triclocarban, naphthalene and methanol. In order to understand the mechanisms of ozone reactions with the organic pollutants, a radical scavenger …

Bubbling to turbulent regime transition in a 2D catalytic fluidized bed reactor
The ozone decomposition reaction was performed in a 2.5cmx40cmx450cm two dimensional (2D) catalytic fluidized bed reactor. Commercial FCC catalyst impregnated with Fe2O3 was used at superficial gas velocities ranging between 0.006 m/s and 0.55 m/s. The onset velocity of the turbulent regime (uc) …

Emission Reduction and Assisted Combustion Strategies for Compression Ignition Engines with Subsequent Testing on a Single-Cylinder Engine
… Chapter three analyzes the effects of ozone-assisted combustion on a single cylinder diesel engine. This work starts with a summarization of the literature in the field, which supports the simplified combustion model for determination of trends. Experimentation results demonstrate the …

In situ laser Raman studies of the mechanism of ethanol oxidation over supported molybdenum oxide
… was carried out in a flow reactor. The effect of ozone appeared below a transition temperature which differed according to the support (523 K on SiO₂, 448 K on Al₂O₃ and 443 K on TiO₂). The reactivity below the transition temperature followed the order SiO₂ > TiO₂ > Al₂O₃, while above it the …
