For 14-pcs Ru catalyst and H2 rate of 6.08 L min−1 (0.43 L(H2) min−1 g−1 catalyst), the conversion efficiency of hydrogen was about 87%.
Temperature distribution of catalyst and fuel conversion efficiency are studied with various feeding rates of reactant and PM under high-temperature and carbon-rich conditions.
Fanson et al. [29] described the microwave-assisted cracking of hydrocarbons in the presence of a precious metal impregnated, metal oxide catalyst, with high conversion efficiency in the presence of carbon at atmospheric pressure.
The scope of this research encompasses the optimization of the Cu concentration for the SR catalyst, evaluation of the NOx conversion efficiency of the LNT catalyst according to the kind of reductant (H2, CO, and DME), and evaluation of the de-NOx performance of the LNT catalyst and a combined system of SR + LNT.
The catalyst exhibited near complete conversion efficiency for propane concentrations up to 50 ppm of propane, which decreased to 95%% at the highest, 100 ppm test point.
The increased rate of volume flow of sodium borohydride resulted in a decreased duration of contact between sodium borohydride and the catalyst, thereby decreasing the conversion efficiency.
Unlike previous studies, the present study focuses on coupling between the problems of pulsating flow pattern and catalyst thermal response and conversion efficiency.
More selective catalysts have been designed for this reaction, but whereas all of these are almost completely deactivated after only 24 h, ZrNbO catalysts still exhibit 82% conversion efficiency after 177 h on stream, its acrolein selectivity remaining unimpaired.
Finally, DBD-catalysts hybrid reaction is proposed and a synergistic effect between plasma-generated reactive species and catalysts is clarified, suggesting that vibrationally excited species are important for enhancing overall methane conversion efficiency with catalysts.
Under optimal conditions catalyst showed visible light to H2 conversion efficiency of 6.63%.
