Destruction of Volatile Organic Compounds by Catalytic Oxidation

Abstract

Volatile organic compounds, emitted by a lot of sources, particularly from gasoline engines of automobiles, are air pollutants that give rise to deleterious health and environmental effects. Total catalytic oxidation is an attractive method in controlling these emissions due the great amounts of energy saved, by the moderate temperature involved. For wide implementation of catalytic combustion, thermally, mechanically and chemically stable catalysts are required. The paper is a short reviewing of the available catalysts and also of the new innovations concerning either enhance of their performances or new better formulations.

Monolith Metal-Oxide-Supported Catalysts: Sorbent for Environmental Application

“…where, ∆x is the relative loss of activity, x the conversion, and indices 0 and t stand for times of exposure [81]. The blockage of active sites as a result of poisoning are discussed in detail elsewhere [62,[79][80][81][82][83]. Table 4 shows the types, treatment, and causes of catalyst deactivation.…”

Kinetics of methyl methacrylate combustion over a Pt/alumina catalyst

“…Among the materials featuring the catalytic activity for VOC's combustion, the most investigated are the supported noble metals, the supported transitional non-noble metals and the transitional metals oxides. [4][5][6][7] So far, the supported noble metal catalysts are the most used in practical applications, as the result of their high activity and the relatively good resistance to deactivation. In this class, the most frequently used are Pt and Pd supported on γ-alumina.…”

Development and characterization of a catalytic membrane for volatile organic compound combustion

“…These symptoms include; headaches, allergic skin reaction, visual disorders, dizziness, coughing, eye and respiratory tract irritation and fatigue. Likewise, brain damage, damage to the nervous, kidney, reproductive and immune systems are associated with long term exposure to VOCs [4]. Emissions of VOCs could be a result of natural sources, although, most VOC emissions result from anthropogenic sources.…”

“…Emissions of VOCs could be a result of natural sources, although, most VOC emissions result from anthropogenic sources. The degree of VOCs released yearly into the atmosphere from man-made sources alone constitute to about 235 million tonnes [4]. From an environmental point of view, curtailing these vapour emissions could lead to a vital landmark in the oil and process industries.…”
