“…In another study, Aissaoui et al [49] developed a stabilized sorbent-catalyst hybrid material (CaO-UGSO10/NiO) with 10% by weight of UGSO and 20% of NiO that was applied in the steam reforming process of Gly. The results of the operation showed production of H 2 with high purity and yields (95% and 93%, respectively).…”

Glycerol and Catalysis by Waste/Low-Cost Materials—A Review

The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, for example. The most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain alcohols, generating fatty acid esters (biodiesel) and a very important by-product, glycerol (Gly). Gly is widely used in different sectors of the industry, and in order to add value to this by-product, heterogeneous catalysis becomes a relevant tool, whether to transform glycerol into other chemical products of interest or even use it in the production of catalysts. Among the several studies found in the literature, the use of low-cost materials and/or wastes from the most diverse activities to prepare active catalytic materials for the transformation of Gly has been increasingly reported due to its valuable advantages, especially related to the cost of raw materials and environmental aspects. Thus, this brief review article presents the relationship between catalysis, low-cost materials, waste, and glycerol, through different studies that show glycerol being transformed through reactions catalyzed by materials produced from low-cost sources/waste or with the glycerol itself used as a catalyst.

“…Some other elements such as Ca, Mn, Ti, and V are found in trace amounts (less than 1 wt %). Promising results have been obtained in our group by valorizing this residue as a Ni-based catalyst (Ni/UGSO) for hydrogen production by glycerol steam reforming. − These findings suggest that this waste might be used as a possible catalytic support and promoter in other patterns. Some UGSO characteristics led us to conclude that it may be a promising candidate for CO 2 hydrogenation into methanol: UGSO is thermally and mechanically stable given that it is generated at high temperatures (>950 °C) and pressures (>1 bar) …”

Valorization of residual materials in the development of catalytic materials has an appealing potential from the perspective of a sustainable development. For the first time, Fe/Mg-containing metallurgical waste (UGSO) was utilized as a support for the development of innovative catalysts for CO2 hydrogenation into methanol. A series of different CuZn/UGSO catalysts were developed by conventional and modified deposition–coprecipitation methods. The addition of Cu/Zn into the structure of Fe3O4/MgxFe y O4 was found to improve Cu2+ and Zn2+ dispersion, while the presence of MgO favors methanol selectivity. Compared to 10Cu7.5Zn/UGSO (10 wt % Cu, 7.5 wt % Zn), the higher methanol yield obtained over 10Cu7.5Zn/UGSO–EtOH (10 wt % Cu, 7.5 wt % Zn, ethanol addition after coprecipitation) is a result of both higher CO2 conversion [attributed to (i) finer particle sizes of CuO and ZnO, (ii) a higher Cu0/Cu+ percentage, and (iii) higher oxygen vacancies and number of strong basic sites on the catalyst surface] and higher methanol selectivity [assigned to (i) the stronger interaction of Cu and ZnO and (ii) a higher number of medium basic sites] in comparison with its counterpart. This residue-based catalyst offers a 150% higher methanol yield than a commercial Cu-based methanol synthesis catalyst at 260 °C and 20 bar. These promising results can open a window to the utilization of this residue as a catalytic support in other CO2 hydrogenation processes.

“…Thus, until alternative hydrogen producing methods are developed and popularized in the industry, the potential of CO 2 valorization toward reducing global CO 2 emissions will remain somewhat limited. Some examples of greener, more renewable hydrogen production methods include water electrolysis (splitting water into hydrogen and oxygen), hydrocarbons dry reforming, or hydrogen production using biomass (gasification, fermentation) or biomass-derived compounds (such as glycerol or bio-oils). − Several studies done in the research group of professor Iliuta already explored greener hydrogen production methods, such as glycerol and bio-oil steam reforming − or photocatalytic conversion. − …”

Carbon capture is an emerging technology that is often mentioned as a potential solution to the global warming crisis. However, most of the captured carbon is now treated as waste, discarded, and not used in any meaningful way. On the other hand, from a sustainable development point of view, CO 2 valorization could be a very appealing approach that offers an economic potential when this compound is recycled into valuable chemical products. In this regard, this state-of-the-art review encompasses a wide range of different processes to achieve the conversion of CO 2 into a large variety of products. It does not focus solely on a specific reaction or method, but rather brings different aspects together to provide a far more complete portrait of this emerging subject. Several methods and approaches are discussed, namely thermochemical, electrochemical, photochemical, photoelectrochemical, biochemical, and plasma-assisted conversion. The current state of CO 2 valorization, as well as emerging alternatives and stimulating prospects, was examined, while bearing in mind the realities that limit the application of such technologies. Special emphasis was placed on the optimization of reaction conditions and the development of materials that ensure the best possible production of valuable and environmentally friendly compounds from CO 2 . This review also highlights the challenges related to the application of CO 2 valorization at an industrial scale, which are also important in directing further research in this domain and assessing the prospects of these technologies. Due to the growing number of published papers on the subject, and the limited number of papers offering such a large perspective, we thus believe that this review will be a valuable addition to guide all researchers involved in the field of CO 2 valorization, but also for industrial and political leaders interested in investing in and developing these promising new technologies.
