Reformate surrogate

Packed metal gauze technology, which is in fact a monolithic reactor design, was used by Castaldi et al. [68] and Roychoudh-ury et al. [69] for the WGS reaction. Reformate surrogate containing 3.6 vol.% carbon monoxide was fed to a single-stage... 

The content of CO in the reformate surrogate could be reduced from 10.6 to 1.05 vol.%, which corresponded to 91% conversion. Somewhat lower temperatures were observed at the shell of the reactor, especially in the inlet section, which was attributed to heat losses to the environment. 

Ahluwalia et al. reported on experiments with cordierite monoliths applied for the preferential oxidation of carbon monoxide [548]. The monoliths had 7.62-cm diameter and 12.7-cm length. A commercial catalyst from Engelhard was used for the experiments, which lit-off even at room temperature. Reformate surrogate was... 

Dudfield et al. performed investigations of compact aluminium fin heat-exchanger reactors for the preferential oxidation of carbon monoxide [549]. The reactors had the dimensions of 46-mm height, 56-mm width and 170-mm length, which corresponded to a 0.44-L volume and 590-g weight. They contained 2 g of catalyst each [328]. Platinum/ruthenium catalyst formulations of various composition were incorporated into different reactors and tested. Reformate surrogate with a... 

It was 30-times higher for the sintered structure and 8-times higher for the shell and tube heat-exchanger. The performance of the reactors was compared at 150 °C, 10-175 Lmin fiow rate of reformate surrogate and 1-17.5 Lmin air addition.

Thormann et cd. [9] investigated the performance of Rh/Al203 and Rh/Ce02 catalysts in hexadecane steam reforming in the low-temperature range from 400 to 700 °C. Full conversion of hexadecane, which served as surrogate for diesel fuel, was achieved at a S/C ratio of 4.0 and 700 °C reaction temperature only over the Ce02-supported sample, which also showed short-term stability for 16h, and the alumina-supported sample suffered from rapid deactivation. 

Dreyer et al. [33] investigated the oxidative steam reforming of diesel surrogates over wash-coated ceramic monoliths carrying 5 wt.% rhodium supported by y-alumina. The conversion of M-decane dropped with increasing S/C ratio because the reaction temperature decreased significantly. The beneficial effect of... 

Chen et al. prepared a catalyst for pre-reforming of gasoline [236]. It was composed of 50 wt.% nickel oxide, 18 wt.% lanthana and the balance alumina. The catalyst was tested at a weight hourly space velocity of between 40 and 168 L (hgcai) at 5-bar pressure and 480 °C reaction temperature. The gasoline surrogate was composed of 74 wt.% isooctane, 20 wt.% xylene, 5 wt.% cyclo-hexane and 1 wt.% 1-octene (average...
