Special Issue Information

Dear Colleagues,

Catalytic combustion has been studied extensively for a variety of catalyst formulations and fuel conversion. In the late 1980’s to early 2000’s catalytic combustion of natural gas was determined to be one of a couple of technologies that can meet ultra-low NOx (i.e., less than 3 ppmV@15% O2) requirements in the power generation industry. The extreme temperature gradients and rapid reaction kinetics are coupled with the requirement to maintain a low pressure thus making the design of the system very challenging. Although the pace of development has slowed recently there is still research continuing primarily due to the attributes associated with catalytic combustion. For example, catalytic combustion enables operation outside the flammability regime and it releases heat directly onto a surface enabling non-conventional heat integration. Furthermore, it has been shown that catalytic combustion has the ability to interrupt the NOx formation pathways and does not allow carbon-based emissions, such as CO and UHC to be released making it a true pollution prevention technique. Finally, there are some very similar performance characteristics with partial oxidation systems. It is anticipated that as synthetic fuels are developed their combustion characteristics will vary yet catalytic combustion may normalize those variations.

This special issue will cover numerous developments in the area of catalytic combustion research.

Abstract:In this work the effects of the modification of hexagonal mesoporous silica, SBA-15 and HMS by doping with ceria (5–20 wt%) on the physico-chemical and catalytic properties of Au (1.5 wt%) supported catalysts were evaluated. Characterizations by N2 physisorption, XRD, XPS, SEM and 29Si1H CP-MAS NMR techniques were performed. The catalytic performances were evaluated in the total oxidation of propene, chosen as model VOC molecule. To this aim, catalytic activity tests were carried out in a tubular fixed-bed reactor under the reactive gas mixture containing 1000 ppm of C3H6 and 9% O2 in He. The hexagonally ordered mesoporous structure of SBA-15 played a key role in stabilizing Au particle size and Au-CeO2 interaction, which are the key factors for propene oxidation activity. On the contrary, ceria deposition disturbed the symmetry of the wormhole HMS silica causing poor Au-CeO2 interaction and poor activity for ceria loading >15 wt%.

Volatile organic compounds (VOCs) are organic chemical compounds such as aldehydes, ketones, and other light weight hydrocarbons. Since they have relatively high vapor pressures under ambient conditions, they vaporize easily and diffuse into the atmosphere. Some VOCs are harmful to human health and the environment, as recognized to cause sick building syndrome, multiple chemical sensitivity, and air pollution such as photo-chemical smog and ground-level ozone. Among the VOCs, toluene is widely used as an organic solvent for paints, printing inks, adhesives, and antiseptics due to its excellent ability to dissolve organic substances. However, toluene has an unpleasant odor and causes sick building syndrome by evaporating into the atmosphere. To protect our health and the environment from such noxious influences, it is necessary to remove toluene released into the atmosphere as much as possible. In our previous studies, we found that employing solid solutions, which have high oxygen release and storage properties, as promoters was effective to establish complete oxidation of VOCs at moderate temperatures. In particular, introduction of a small amount of SnO2, which has been well-known as a typical n-type semiconductor with electronic conduction, into the CeO2-ZrO2 lattice considerably facilitated the VOCs oxidation. However, thermal stability of the toluene oxidation catalysis on the Pt/CeO2-ZrO2-SnO2 catalysts was not enough due to readily-reducibility of SnO2.In this study, we focused on zinc oxide (ZnO), also known as a stable n-type semiconductor, and a 0.4wt%Pt/Ce0.76Zr0.19Zn0.05O1.95 catalyst was prepared. The catalytic toluene oxidation activity of this catalyst was investigated and calcination temperature dependence on the toluene oxidation activity was characterized. It was confirmed that only CO2 and steam were produced by the complete oxidation of toluene, and no toluene-derived compounds were detected as by-products with a gas chromatography mass spectrometer. Toluene was completely oxidized at 320 °C on the 0.4wt%Pt/Ce0.76Zr0.19Zn0.05O1.95 catalyst calcined at 500 °C. The toluene oxidation activity slightly decreased with increasing the calcination temperature of the catalyst. However, significant deactivation was not recognized in the present 0.4wt%Pt/Ce0.76Zr0.19Zn0.05O1.95 catalyst, and toluene was completely oxidized at 360 °C even after calcination at 1000 °C. From these results, it became obvious that the 0.4 wt%Pt/Ce0.76Zr0.19Zn0.05O1.95 catalyst has high thermal stability for toluene oxidation activity.

Abstract: This paper will be discussing a Rh-based pyrochlore catalyst used for diesel reforming for fuel cell application. The paper will include pre- and post-reaction characterization of the catalyst. Also, it will report results from a 1 000-hr diesel reforming test on a powder pyrochlore catalyst developed by NETL over an oxygen-conducting support demonstrates that the catalyst and support compositions selected have significant potential in a commercial reforming application. Complete hydrocarbon conversion and near equilibrium syngas yields with no signs of catalyst deactivation (olefin formation, pressure buildup, etc.) were observed during reforming of diesel fuel over pyrochlore-based catalyst.
