“…Reports on the direct synthesis of oxygenates from CO 2 are quite scarce. Dagle et al [220] report a multifunctional catalytic system formed by mixing several catalysts accounting for different functions. By mixing an Fe-based FTS catalyst, and CuZn-based and PdZn-based methanol synthesis catalysts in a 1:1:1 weight ratio around 500 g L cat −1 h −1 total STY to oxygenates (methanol, ethanol, and acetic acid) was obtained at 350 • C, 80 bar, and 50,000 h −1 .…”

Nowadays, global climate change is likely the most compelling problem mankind is facing. In this scenario, decarbonisation of the chemical industry is one of the global challenges that the scientific community needs to address in the immediate future. Catalysis and catalytic processes are called to play a decisive role in the transition to a more sustainable and low-carbon future. This critical review analyses the unique advantages of structured reactors (isothermicity, a wide range of residence times availability, complex geometries) with the multifunctional design of efficient catalysts to synthesise chemicals using CO2 and renewable H2 in a Power-to-X (PTX) strategy. Fine-chemistry synthetic methods and advanced in situ/operando techniques are essential to elucidate the changes of the catalysts during the studied reaction, thus gathering fundamental information about the active species and reaction mechanisms. Such information becomes crucial to refine the catalyst’s formulation and boost the reaction’s performance. On the other hand, reactors architecture allows flow pattern and temperature control, the management of strong thermal effects and the incorporation of specifically designed materials as catalytically active phases are expected to significantly contribute to the advance in the valorisation of CO2 in the form of high added-value products. From a general perspective, this paper aims to update the state of the art in Carbon Capture and Utilisation (CCU) and PTX concepts with emphasis on processes involving the transformation of CO2 into targeted fuels and platform chemicals, combining innovation from the point of view of both structured reactor design and multifunctional catalysts development.

“…As a matter of fact, a number of methods for extracting elemental sulfur from H 2 S have been developed and followed already since the establishment of Claus process in industry [6,7]. Concerning CO 2 , however, its efficient conversion into valuable products such as fuels and chemicals is so far a global challenge [8][9][10][11]. Diverse approaches including catalysis have been resorted to overcome the barriers to the activation and transformation of CO 2 [9,12,13].…”

“…Carbon dioxide (CO 2 ) is a relatively abundant natural carbon resource [1][2]. Because of increasing anthropogenic levels and the foreseeable impact it will have on the environment, research efforts have focused on capturing CO 2 and then sequestering or catalytically converting it to energy-rich chemical products [1,3,4]. The chemicals produced by this route would ideally replace an equivalent amount currently produced using fossil fuels as feedstock, contributing to the overall reduction of carbon emissions [5,6].…”

A new Langmuir–Hinshelwood–Hougen–Watson (LHHW) type kinetic model is developed for carbon dioxide hydrogenation over a precipitated Fe/Cu/K catalyst in a continuous spinning basket reactor. A number of possible reaction sets originating from the combination of the formate mechanism for the water gas shift reaction and the enolic mechanism for the Fischer–Tropsch synthesis, with various rate determining steps, are considered. The results show that the CO2 hydrogenation process is limited by the reaction between surface CO and hydrogen species to form enolic (HCO) units. This surface reaction is the key reaction step in producing higher hydrocarbons by the Fischer–Tropsch synthesis.
