“…The reforming of natural gas with CO 2 (the DRM process) is a very attractive reaction in terms of both the academic study of syngas production and industrial utilization, as it offers several advantages: a) mitigation of CO 2 and natural gas; b) transformation of natural gas and CO 2 into valuable syngas; c) effective utilization of low-grade natural gas resources consisting of natural gas and CO 2 ; d) producing syngas with a high CO/H 2 ratio.

The mitigation and utilization of greenhouse gases, such as carbon dioxide and methane, are among the most important challenges in the area of energy research. Dry reforming of CH4 (DRM), which uses both CO2 and CH4 as reactants, is a potential method to utilize the greenhouse gases in the atmosphere. Natural gas containing high concentrations of CO2 and CH4 could therefore be utilized for hydrogen and synthesis gas (syngas) production in the near future, without need for the removal of CO2 from the source gas. Thus, the DRM reaction is a suitable process to convert CH4 and CO2 to syngas, which is a raw material for liquid fuel production, through the Fischer–Tropsch process. Herein, the development of CO2 reforming for syngas production is reviewed, covering process chemistry, catalyst development, and process technologies as well as the potential future direction for this process.

“…For the egg-shell catalysts, the metallic active phase was distributed only on a thin external surface layer of γ-Al 2 O 3 carrier spheres, but not in the internal pores. 15 Such arrangement is congruent with a low-contact time process, controlled by external mass transfer phenomena: 16 the reaction takes place on the catalyst surface, easily and quickly accessible by the reagents, which would have limited possibility to diffuse and react inside the pores. For the egg-yolk catalysts, the metallic active phase was embedded in a mixture of porous γ-and θ-Al 2 O 3 , 12 to limit the sintering of Rh clusters under the severe CH 4 CPO environment.…”

Short contact time catalytic partial oxidation (SCT-CPO) of natural gas is a promising technology for syngas production, representing an appealing alternative to existing processes. This process is likely to become more important in the future due to its advantages in thermodynamics, mildly exothermic overall reaction, and H 2 /CO ratio of 2, ideal for downstream processes. Rh catalysts are preferred among those based on noble metals because they avoid coke deposition. However, Rh is very expensive. Thus, the design of nanocomposite catalysts with the minimum Rh load for a feasible industrial process is the aim of the present work: 0.25, 0.5, and 1% Rh load were considered. The catalytic reactor is made of a fixed bed of Rh deposited on both Al 2 O 3 spheres in an egg-shell configuration and Al 2 O 3 irregular particles in an egg-yolk configuration. The weight hourly space velocity (WHSV) was varied from 130 to 460 N L h -1 g cat -1. The 0.5% Rh in the egg-yolk configuration allowed the highest CH 4 conversion (>90%) and H 2 selectivity (>98%) values at any tested WHSV.
