“…Pompeo et al 37 and Lui et al 38 reported similar results for conversions of CO 2 via dry reforming at elevated temperatures. Haag et al 39 also demonstrated that the calculated equilibrium conversion of CO 2 in dry reforming reactions is greater than 90% at temperatures above 850 C. At that temperature, the conversion of CO 2 was near or above 90% for each case in this work. On the other hand, Haag et al also demonstrated that CO 2 conversion at 750 C was in the 80% range.…”

in Wiley Online Library (wileyonlinelibrary.com) High-temperature CO 2 selective membranes offer potential for use to separate flue gas and produce a warm, pure CO 2 stream as a chemical feedstock. The coupling of separation of CO 2 by a ceramic-carbonate dual-phase membrane with dry reforming of CH 4 to produce syngas is reported. CO 2 permeation and the dry reforming reaction performance of the membrane reactor were experimentally studied with a CO 2 -N 2 mixture as the feed and CH 4 as the sweep gas passing through either an empty permeation chamber or one that was packed with a solid catalyst. CO 2 permeation flux through the membrane matches the rate of dry reforming of methane using a 10% Ni/c-alumina catalyst at temperatures above 750 C. At 850 C under the reaction conditions, the membrane reactor gives a CO 2 permeation flux of 0.17 mL min 21 cm 22, hydrogen production rate of 0.3 mL min 21 cm 22 with a H 2 to CO formation ratio of about 1, and conversion of CO 2 and CH 4 , respectively, of 88.5 and 8.1%.

By contrast, CO disproportionation is an exothermic reaction and its equilibrium constant decreases with increasing temperature [23]. The decrease in the conversion of CH 4 during the reaction was due to the deposition of coke on the surface of the catalyst.…”

Zeolite-supported Ni catalyst for methane reforming with carbon dioxide

In the present work, we compare the catalytic behaviour, in the dry reforming of methane, of Ni-based Silicalite-1 type catalyst obtained by different postsynthesis treatments. The Silicalite-1 type material, used as Ni-support, has been treated in order to observe the role of the silanol groups on the Ni impregnation, and then on the overall catalyst performance. Among the applied treatments (ionic-exchange, calcinations and silylation), the silylation is the one that allows the formation of smaller and more reducible Ni-oxide species that not only improve the methane conversion but also reduce the deactivation of the catalyst, due to the coke deposition.

The steam reforming of the main biodiesel by-product, glycerol, has been catching up the interest of the scientific community in the last years. The use of glycerol for hydrogen production is an advantageous option not only because glycerol is renewable but also because it's use would lead to the decrease of the price of biodiesel, thus making it more competitive. Consequently, the use of biodiesel at large scale would significantly reduce CO2 emissions comparatively to fossil fuels. Moreover, hydrogen itself is seen as a very attractive clean fuel for transportation purposes.Therefore, the industrialization of the glycerol steam reforming (GSR) process would have a tremendous global environmental impact. In the last years, intensive research regarding GSR thermodynamics, catalysts, reaction mechanisms and kinetics, and innovative reactor configurations (sorption enhanced reactors (SERs) and membrane reactors (MRs)) has been done, aiming for improving the process effectiveness. In this review, the main challenges and strategies adopted for optimization of GSR process are addressed, namely the GSR thermodynamic aspects, the last developments on catalysis and kinetics, as well as the last advances on GSR performed in SERs and MRs.
