Dry and Steam Reforming Technologies, and Application in Chemical Engineering

Dear Colleagues,

Industrially, hydrogen gas is largely produced by the reforming of methane. By far, the reforming of methane with steam at high temperature, known as steam reforming, is the leading technology for producing hydrogen and synthesis gas with CO:H₂ ratio close to unity. Synthesis gas (syngas) is a building block for the manufacture of bulk such as hydrogen (H₂), methanol (CH₃OH), and liquid synthetic motor fuels (gasoline (C₅–C₁₂), naphtha (C₈–C₁₂), kerosene (C₁₁–C₁₃), and diesel (C₁₂–C₂₂)). On the other hand, the reforming of methane with carbon dioxide is an excellent alternative process which can be environmentally friendly as it utilizes CO₂, the greenhouse gas. Moreover, these two reforming processes are attractive ways to utilize the vast reserves of natural gas. At present, biogas is freely available as a source of methane, but it has a significant amount of CO₂, which may be more suitable for dry reforming than steam reforming, and finally yields the desired unity H₂/CO ratio for the Fischer–Tropsch process. Both reforming processes are highly endothermic reactions, and hence require high temperature (550–700 °C). The endothermic nature of this process favors the carbonaceous deposition, which deactivates the catalyst and limits its usage. Nickel-based catalysts are commonly accepted for the DRM process due to their low cost, but are prone to deactivation at high temperatures, and so bimetallic catalysts were introduced.

This Special Issue on “Dry and Steam Reforming Technologies, and Application in Chemical Engineering” aims to curate novel advances in the development and application of steam and dry reforming of methane to address contemporary issues in chemical engineering such as energy and environment. This Special Issue invites high-quality papers on topics including, but not limited to:

• Fundamental studies on the kinetics and mechanism of deactivation in the dry and steam reforming process;
• Development low-cost, durable, coke-resistant and highly selective multifunctional catalysts for dry and steam reforming;
• Experimental and theoretical studies related to advanced support materials and co-catalysts;
• Exploring the techno-economic analysis of dry and steam reforming and hybrid processes;
• Kinetic modelling of the reforming process to optimize the process parameters.
