“…In dry reforming of real natural gas (NG) containing up to 6% of C2-C4 alkanes also high and stable performance of structured catalyst was demonstrated for concentrated feed (Figure 6). This advantage of structured catalysts on heat-conducting metal/cermet substrates allowed to carry out efficient transformation of a lot of fuels including gasoline and diesel into syngas via partial oxidation and steam/autothermal reforming [82][83][84][85][86][87]117,[139][140][141][142]. Reforming of biofuels such as acetone, ethyl acetate and glycerol is known to be accompanied by gas-phase reactions yielding ethylene, which is easily transformed into coke on catalysts.…”

This review considers problems related to design of efficient structured catalysts for natural gas and biofuels transformation into syngas. Their active components are comprised of fluorite, perovskite and spinel oxides or their nanocomposites (both bulk and supported on high surface area Mg-doped alumina or MgAl2O4) promoted by platinum group metals, nickel and their alloys. A complex of modern structural, spectroscopic and kinetic methods was applied to elucidate atomic-scale factors controlling their performance and stability to coking, such as dispersion of metals/alloys, strong metal-support interaction and oxygen mobility/reactivity as dependent upon their composition and synthesis procedures. Monolithic catalysts comprised of optimized active components loaded on structured substrates with a high thermal conductivity demonstrated high activity and stability to coking in processes of natural gas and biofuels reforming into syngas. A pilot-scale axial reactor equipped with the internal heat exchanger and such catalysts allowed to efficiently convert into syngas the mixture of natural gas, air and liquid biofuels in the autothermal reforming mode at low (~50–100 °C) inlet temperatures and GHSV up to 40,000 h−1.

“…On the other hand, in applications, such as catalytic reforming of fuel into syngas and hydrogen [1][2][3], it is necessary to optimize the atomization process for regimes with low fuel flow rate, limited by the effective area of the catalyst. In such applications in is needed to ensure a high degree of mixture homogeneity, which is necessary for the correct operation of the catalyst.…”

Nozzle prototype for a diesel fuel reformer was investigated using numerical simulation. The main goal was to increase the rate and degree of fuel evaporation, as well as to improve the mixing characteristics between diesel fuel and superheated steam. A nozzle design was proposed with two internal regions, in which jets with opposite swirl directions were created. The simulation of mixing and evaporation of liquid fuel droplets and steam jets was performed in a finite volume formulation. The results of simulations show good uniformity of the mixture concentration downstream the nozzle exit, as well as high degree of evaporation, which is important for catalytic processes.

“…High activity and stability, however, are threatened by the above-mentioned coke deposits and, additionally, by adsorbing sulfur-and phosphorouscontaining components, which might block the catalytically-active sites on the catalyst surface being no longer accessible for the reactants. There are numerous papers in the literature regarding experimental investigations in this respect [48][49][50][51][52][53][54][55][56][57][58][59][60]. Although the formation of coke deposits on the catalyst surface is known to be one of the most important reasons for catalyst deactivation, only a few papers deal with a priori technical approaches to suppress them [23,[61][62][63][64].…”
