Special Issue Information

Dear Colleagues,

The global demand for energy is steadily increasing, mainly because of the increasing population. Current energy production is heavily dependent on fossil fuels and emits greenhouse gases. Carbon dioxide (CO2), whose emission is steadily increasing, is one of the major components of greenhouse gases emitted into the Earth’s atmosphere due to human activities and is comprised of ~82% of the total greenhouse gases emitted. The increasing amount of CO2 emission over the decades has raised serious environmental concerns. At the current level of the CO2-emission rate, the global temperature is projected to rise by 2–5 0C this century above the preindustrial level. Therefore, CO2 management is one of the most challenging issues of the current generation.

Various schemes of carbon management have been put forward as ways to tackle this issue. Among them, chemical conversion of CO2, which is enabled by the use of catalysts, is one of the promising ways to transform CO2 to fuels and chemicals. Thus, generated fuels and chemicals can be directly used as fuels or feedstocks in existing industrial processes without a need to reinvent the new infrastructures.

This Special Issue, therefore, seeks to contribute to a fundamental understanding of the catalytic hydrogenation of CO2 to fuels and feedstock chemicals. Topics of interest for publication include but are not limited to the following:

Experimental (ex-situ and in-situ) and theoretical studies of

-Catalytic CO2 conversion;

-Reactions of CO2 with molecules;

-Catalyst design for CO2 conversion and reaction of CO2 with other molecules.

Abstract
Three Ni-based natural gas steam reforming catalysts, i.e., commercial JM25-4Q and JM57-4Q, and a laboratory-made catalyst (26% Ni on a 5% SiO2–95% Al2O3), are tested in a laboratory reactor, under carbon dioxide methanation and methane steam reforming [...] Read more.
Three Ni-based natural gas steam reforming catalysts, i.e., commercial JM25-4Q and JM57-4Q, and a laboratory-made catalyst (26% Ni on a 5% SiO2–95% Al2O3), are tested in a laboratory reactor, under carbon dioxide methanation and methane steam reforming operating conditions. The laboratory catalyst is more active in both CO2 methanation (equilibrium is reached at 623 K with 100% selectivity) and methane steam reforming (92% hydrogen yield at 890 K) than the two commercial catalysts, likely due to its higher nickel loading. In any case, commercial steam reforming catalysts also show interesting activity in CO2 methanation, reduced by K-doping. The interpretation of the experimental results is supported by a one-dimensional (1D) pseudo-homogeneous packed-bed reactor model, embedding the Xu and Froment local kinetics, with appropriate kinetic parameters for each catalyst. In particular, the H2O adsorption coefficient adopted for the commercial catalysts is about two orders of magnitude higher than for the laboratory-made catalyst, and this is in line with the expectations, considering that the commercial catalysts have Ca and K added, which may promote water adsorption.
