“…The synthesized catalysts were active and stable in the ATR of diesel fuel of various types, including those with a high content of aromatic hydrocarbons. The catalysts demonstrated high efficiency in the conversion of other liquid hydrocarbon fuels (gasoline and biodiesel) into synthesis gas [ 18 , 92 ]. The oxidative regeneration of catalysts was proved feasible; the conditions for stable catalyst operation were determined.…”

“…Since the coefficient of thermal expansion (CTE) of high-temperature metal alloys twice exceeds that of oxide coatings, the latter often suffer cracking and destruction during heating. This problem was addressed in recent works on the development of a catalyst for diesel fuel ATR, carried out at the Boreskov Institute of Catalysis, SB RAS [ 18 , 48 , 49 , 50 , 51 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ]. An elegant approach has been proposed based on supporting a needle-shaped coating instead of a continuous catalytic layer [ 90 ].…”

The paper considers the current state of research and development of composite structured catalysts for the oxidative conversion of liquid hydrocarbons into synthesis gas for fuel cell feeding and gives more detailed information about recent advances in the Boreskov Institute of Catalysis. The main factors affecting the progress of the target reaction and side reactions leading to catalyst deactivation are discussed. The properties of the Rh/Ce0.75Zr0.25O2/Al2O3/FeCrAl composite multifunctional catalyst for the conversion of diesel fuel into synthesis gas are described. The results of the catalyst testing and mathematical modeling of the process of diesel fuel steam–air conversion into synthesis gas are reported.

“…The H 2 deficit due to CH 4 formation was also neglected in the model, which assumes ideal conditions for H 2 formation. Moreover, it has been experimentally demonstrated that the molar fraction of CH 4 in the reformate from autothermal reforming is usually less than 0.5% 30 or not more than 2% in some cases of hexadecane reforming on a different catalyst 35 so the error of the model introduced here due to the exclusion of the methanation reaction is negligible.…”

Hydrogen for the use in electrochemical fuel cells (FCs) can be obtained from diesel's sourced energy. A small scale process of the catalytic auto-thermal reforming (ATR) with the operational water-gas shift (WGS) for the production of hydrogen with suitable purity grade as a resource in the high temperature polymer membrane redox FCs (HT-PEMFCs) for auxiliary power systems was proposed. The reactors for hydrocarbon ATR dehydrogenation reactions, WGS processor serial treatment and downstream were designed. Technology was simulated using Aspen Plus software. Gibbs minimization was applied to validate the product compound composition for both units' yields, modelling was analysed, and the heat at the ATR device fluid inlet, the potential of pressure, feed, the influence of the oxygen to carbon (C) amount ratio, and the steam to total indicated C equivalent were investigated. one dimensional models were used for ATR/WGS. The first was considered as a plug flow, while the latter as packed-bed vessel. Particular kinetic parameters were estimated from literature; other functional conditions were specified. Combined sequential results, assessed from calculations, allow for a successful engineered construction, operation and intensification of ATR, which requires a good physical understanding, but also control of thermodynamic equilibria, transport phenomena and mechanistic chemical rates.

“…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.
