“…Autothermal reforming of the methane (ATRM) process provides syngas production with varying ranges of the H 2 /CO ratio, which can be manipulated using the relative concentrations of CO 2 and O 2 in the feed. 156 The presence of oxygen in the feed is helpful in inhibiting catalyst deactivation due to carbon deposition. 157 Autothermal reforming (ATR) of the methane (natural gas) process comprises both steam reforming and a partial oxidation reaction, consisting of both exothermic and endothermic reactions.…”

Annually billions of cubic meters of natural gas are flared around the globe at various oil and gas production sites. Natural gas flaring practices waste valuable energy resources that can be used for economic support and will also be beneficial to mitigate global warming effects. In this review, an overview of natural gas flaring impacts with respect to the environment with special emphasis on global annual natural gas flaring emissions and their reformation to energy-efficient fuels has been discussed. Initially, natural gas flaring emissions and their impacts in view of environmental pollution and global warming effects have been highlighted. The strategies to mitigate wastage to valuable energy resources through various flaring management strategies are also evaluated. In the main stream, various gas flaring reductions and utilization technologies based on their applications in the oil and gas industry and especially for remote oil and gas fields are discussed. Liquified natural gas (LNG) and compressed natural gas (CNG) technologies have been identified as the main gas flaring reduction methods based on their applicability, commerciality, and economical potential. In addition, gas to liquid (GTL) has been an advancing technology for the past many years toward its utilization of methane as a feed and converting it to useful industrial products such as synthesis crude and methanol. Finally, reformation technologies for synthesis gas (syngas) production such as thermal reforming, plasma reforming, and photoreforming are deliberated. Based on feed gas mixture, different reforming processes such as steam reforming of methane (SRM), dry reforming of methane (DRM), and bi-reforming of methane (BRM) are evaluated for hydrogen-rich syngas production. The future perspectives regarding gas flaring utilization technologies advancement with further improvements in utilization of flared gas to efficient energy fuels are proposed.

“…The decisive step for higher PTF efficiencies for FT products by Schemme et al [119] was the integration of an autothermal reformer (ATR), leading to a product mix of 75:25 for diesel and jet fuel. Such an ATR has been developed at the Research Centre Jülich, and has been reported on by Pasel et al [120], amongst others. The ATR converts short-chain alkanes such as LPG and crude naphtha into syngas.…”

Achieving the CO2 reduction targets for 2050 requires extensive measures being undertaken in all sectors. In contrast to energy generation, the transport sector has not yet been able to achieve a substantive reduction in CO2 emissions. Measures for the ever more pressing reduction in CO2 emissions from transportation include the increased use of electric vehicles powered by batteries or fuel cells. The use of fuel cells requires the production of hydrogen and the establishment of a corresponding hydrogen production system and associated infrastructure. Synthetic fuels made using carbon dioxide and sustainably-produced hydrogen can be used in the existing infrastructure and will reach the extant vehicle fleet in the medium term. All three options require a major expansion of the generation capacities for renewable electricity. Moreover, various options for road freight transport with light duty vehicles (LDVs) and heavy duty vehicles (HDVs) are analyzed and compared. In addition to efficiency throughout the entire value chain, well-to-wheel efficiency and also other aspects play an important role in this comparison. These include: (a) the possibility of large-scale energy storage in the sense of so-called ‘sector coupling’, which is offered only by hydrogen and synthetic energy sources; (b) the use of the existing fueling station infrastructure and the applicability of the new technology on the existing fleet; (c) fulfilling the power and range requirements of the long-distance road transport.

Reliable electrical and thermal energy supplies are basic requirements for modern societies and their food supply. Stand-alone stationary power generators based on solid oxide fuel cells (SOFC) represent an attractive solution to the problems of providing the energy required in both rural communities and in rurally-based industries such as those of the agricultural industry. The great advantages of SOFC-based systems are high efficiency and high fuel flexibility. A wide range of commercially available fuels can be used with no or low-effort pre-treatment. In this study, a design process for stand-alone system consisting of a reformer unit and an SOFC-based power generator is presented and tested. An adequate agreement between the measured and simulated values for the gas compositions after a reformer unit is observed with a maximum error of 3 vol% (volume percent). Theoretical degradation free operation conditions determined by employing equilibrium calculations are identified to be steam to carbon ratio (H2O/C) higher 0.6 for auto-thermal reformation and H2O/C higher 1 for internal reforming. The produced gas mixtures are used to fuel large planar electrolyte supported cells (ESC). Current densities up to 500 mA/cm2 at 0.75 V are reached under internal reforming conditions without degradation of the cells anode during the more than 500 h long-term test run. More detailed electrochemical analysis of SOFCs fed with different fuel mixtures showed that major losses are caused by gas diffusion processes.
