“…It is an adiabatic ideal plug flow reactor using commercial Cu/ZnO/Al 2 O 3 catalyst. This catalyst was studied by several authors [46,47] for the methanol production from CO 2 , although it is less efficient with supply of CO 2 than CO/CO 2 [47]. The catalyst density is equal to 1775 kg cat /m 3 cat , the fixed bed porosity is 0.5, the pellet diameter is 0.000055 m, and the pellet height is 0.00003 m [12].…”

Carbon dioxide conversion and utilization is gaining significant attention worldwide, not only because carbon dioxide has an impact on global climate change, but also because it provides a source for potential fuels and chemicals. Methanol is an important fuel that can be obtained by the hydrogenation of carbon dioxide. In this research, the modeling of a reactor to produce methanol using carbon dioxide and hydrogen is carried out by way of an ANOVA and a central composite design. Reaction temperature, reaction pressure, H 2 /CO 2 ratio, and recycling are the chosen factors, while the methanol production and the reactor volume are the studied responses. Results show that the interaction AC is common between the two responses and allows improvement of the productivity in reducing the volume. A mathematical model for methanol production and reactor volume is obtained with significant factors. A central composite design is used to optimize the process. Results show that a higher productivity is obtained with temperature, CO 2 /H 2 ratio, and recycle factors at higher, lower, and higher levels, respectively. The methanol production is equal to 33,540 kg/h, while the reactor volume is 6 m 3 . Future research should investigate the economic analysis of the process in order to improve productivity with lower costs.

“…Electrochemistry is an important enabling technology because this involves converting electrical energy to chemical energy. In one study, CO 2 reacted with electrolytic hydrogen to produce methanol and water (14)(15)(16), while in another concept, methane was produced when CO 2 reacted with electrolytic hydrogen (with condensation of water to shift the equilibrium and achieve good yields) (17). However, direct electrochemical reduction of CO 2 to hydrocarbons would be more efficient, simpler and time saving.…”

The increasing atmospheric levels of carbon dioxide (CO 2 ) must be controlled or better reverted to avoid undesirable climate changes. The electrochemical reduction of CO 2 into hydrocarbons is the best approach to solve this problem because it will recycle the 'spent' CO 2 , known as carbon neutral cycle, and will probably be able to remit the energy crises. Nanostructured copper is a novel material known for the efficient and selective reduction of CO 2 into hydrocarbons. This review attempts to summarize the recent development of enlarged surface area nanostructured copper for the efficient reduction of CO 2 into hydrocarbons using renewable energy resources at low overpotentials. The effects of different reaction conditions (e.g. applied potential, CO 2 concentration and electrode surface) on the products and some relationships between these conditions and products are discussed here. Latest achievements in the CO 2 electroreduction technology, remaining challenges and perspective research directions for practical applications are also presented. ARTICLE HISTORY

Vulcan XC-72R-supported Fe catalysts have been synthesised for the electroreduction of CO 2 to high-added value products. Catalysts were obtained by the polyol method, using ethylene glycol as solvent and reducing agent. Prior to the metal deposition, Vulcan was subjected to different oxidation treatments in order to modify its surface chemistry and study its influence on the physicochemical and electrochemical properties of the catalysts, as well as on the product distribution. The oxidation treatments of the supports modify their textural properties, but do not affect significantly the physicochemical properties of catalysts. However, DEMS studies showed that the carbon support degradation, the distribution of products, and the catalytic activity toward the CO 2 electroreduction reaction depend significantly on the surface chemistry of the carbon support.
