“…The O1s spectrum characteristic of oxygen is clearly observed at a binding energy at 530 eV. Al2p can be observed with a typical binding energy of 74 eV [25]; thus, it was determined that the Al atoms are in the oxide form, and can act as catalyst supports [26]. Figure 2b shows the peaks in the range between 850 and 900 eV.…”

Abstract:To contribute to the search for an oxygen-free biodiesel from vegetable oil, a process based in the oleic acid hydrodeoxygenation over Ni/γ-Al 2 O 3 catalysts was performed. In this work different wt % of Ni nanoparticles were prepared by wetness impregnation and tested as catalytic phases. Oleic acid was used as a model molecule for biodiesel production due to its high proportion in vegetable oils used in food and agro-industrial processes. A theoretical model to optimize yield of n-C 17 was developed using size, distribution, and wt % of Ni nanoparticles (NPs) as additional factors besides operational conditions such as temperature and reaction time. These mathematical models related to response surfaces plots predict a higher yield of n-C 17 when physical parameters of Ni NPs are suitable. It can be of particular interest that the model components have a high interaction with operation conditions for the n-C 17 yields, with the size, distribution, and wt % of Ni NPs being the most significant. A combination of these factors statistically pointed out those conditions that create a maximum yield of alkanes; these proved to be affordable for producing biodiesel from this catalytic environmental process.

“…In terms of reactor design, the inner passageways are metal conduits aligned co-axially with the reactor conduit, and are capable of facilitating heat transfer (from partial oxidation reaction) to the reformer. In a recent invention, Olah and Prakash (2013) advocated the method of forming methanol, in which the DRM reaction is combined with the conventional steam reforming of methane at a specified ratio in a process described as bi-reforming reaction. In this reaction, the methane, CO 2 , and water are reacted in the ratio of 3:2:1 as shown below:…”

“…The bi-reforming reaction catalyzed on a Ni-supported on high surface area or nanostructured support is able to suppress coke formation and produces syngas in the ratio of 2H 2 :CO (Olah and Prakash, 2013). This ratio is the right amount required for methanol production, which is used as a building block in the chemical industry.…”

This paper presents a review on the developments in catalyst technology for the reactions utilizing CO 2 for high-temperature applications. These include dehydrogenation of alkanes to olefins, the dehydrogenation of ethylbenzene to styrene, and finally CO 2 reforming of hydrocarbon feedstock (i.e., methane) and alcohols. Aspects on the various reaction pathways are also highlighted. The literature on the role of promoters and catalyst development is critically evaluated. Most of the reactions discussed in this review are exploited in industries and related to on-going processes, thus providing extensive data from literature. However, some reactions, such as CO 2 reforming of ethanol and glycerol, which have not reached industrial scale, are also reviewed owing to their great potential in terms of sustainability, which is essential as energy for the future. This review further illustrates the building-up of knowledge that shows the role of support and catalysts for each reaction and the underlying linkage between certain catalysts, which can be adapted for the multiple CO 2 -related reactions.

“…The packing in gas–solid trickle bed reactor may be in the form of Pall or Raschig rings, but Verver and van Swaaij found that regularly stacked packing further minimized pressure drop and static solids hold‐up, and provided rapid radial solid distribution throughout the column. Recently, Obradović et al introduced a novel structured plate‐type catalyst in the form of a static mixer with corrugated plates, which is an excellent example of the regularly stacked type packing described above. Static mixers with corrugated plates (e.g., the SMV mixer) induce intense radial mixing for shortest space requirements …”

The sorption reaction CaO–CO2 was examined in a countercurrent gas–solid trickle flow reactor with regularly stacked packing at T = 500–600°C, pCO2 = 40–50 kPa, solid‐phase fluxes S = 0.3–0.5 kg m−2 s−1, and CaO particles of 500–710 μm in size. Sorption kinetics was evaluated by thermogravimetric (TG) technique. The random pore model was used for the description of the carbonization reaction. Hydrodynamic characteristics of gas–solid trickle flow were estimated at room temperature and ambient pressure. Plug flow model of both gas and solid‐phase, with the parameters obtained from TG and hydrodynamics experiments, satisfactorily described the sorption process in countercurrent gas–solid trickle flow reactor. © 2015 American Institute of Chemical Engineers AIChE J, 61: 1601–1612, 2015
