“…conversion drop lower than 0.1 suggesting that above 200 °C, for zeolites, the inhibitory effects of water on dimethyl ether formation can be neglected as also reported in a previous study for MFI-type zeolites [29] . Such results propose that the deactivation of Cu-Zn-ZrO 2 /FER hybrid grain during CO 2 -to-DME process observed by Frusteri et al [37] can be fairly related to deactivation of the metal sites (i.e. sintering) rather than the acid sites of zeolite.…”

“…MFI, MOR, Y) was also demonstrated during either CO or CO 2 one-pot conversion to DME, coupling zeolites with copper-based catalyst via co-precipitation method [35,36] . Nevertheless, Frusteri et al [37] observed an important deactivation of Cu-Zn-ZrO 2 /FER hybrid grain during CO 2to-DME process, and the authors attributed this behaviour to the water produced during the reactions, that progressively deactivates both metal and acid sites but no experimental evidences were reported to confirm this assumption.…”

“…Different strategies have been applied to prepare the bifunctional catalysts for the direct DME synthesis. For instance, methods including impregnation, co-precipitation [ 158 , 159 , 160 , 161 , 162 ] or sol-gel steps (or their combinations) [ 44 , 163 ] and even more sophisticated approaches leading to core–shell catalyst structures [ 164 , 165 , 166 ] have been reported. Nevertheless, there are different opinions on the efficiency of bifunctional catalysts in comparison to admixed systems.…”

“…Beside acidity, the textural properties of zeolite crystals also strongly affect the catalytic behaviour of hybrid catalysts. In this regard, the one-pot CO 2 -to-DME reaction in the presence of hybrid grains prepared via co-precipitation of CuZnZr precursors over zeolite crystals with different channel systems (i.e., MOR, FER and MFI) was recently investigated [ 158 ]. The microscopy analysis of hybrid grains revealed that zeolite crystal features strongly affect the metal-oxide(s) distribution, producing a very homogenous distribution over lamellar FER-type crystals and a formation of metal clusters on the other zeolite crystals.…”

CO2 Recycling to Dimethyl Ether: State-of-the-Art and Perspectives

This review reports recent achievements in dimethyl ether (DME) synthesis via CO2 hydrogenation. This gas-phase process could be considered as a promising alternative for carbon dioxide recycling toward a (bio)fuel as DME. In this view, the production of DME from catalytic hydrogenation of CO2 appears as a technology able to face also the ever-increasing demand for alternative, environmentally-friendly fuels and energy carriers. Basic considerations on thermodynamic aspects controlling DME production from CO2 are presented along with a survey of the most innovative catalytic systems developed in this field. During the last years, special attention has been paid to the role of zeolite-based catalysts, either in the methanol-to-DME dehydration step or in the one-pot CO2-to-DME hydrogenation. Overall, the productivity of DME was shown to be dependent on several catalyst features, related not only to the metal-oxide phase—responsible for CO2 activation/hydrogenation—but also to specific properties of the zeolites (i.e., topology, porosity, specific surface area, acidity, interaction with active metals, distributions of metal particles, …) influencing activity and stability of hybridized bifunctional heterogeneous catalysts. All these aspects are discussed in details, summarizing recent achievements in this research field.

“…In this regard, production of bio-methane via waste conversion is a strategy to strongly increase the sustainability of several processes, from energy to chemical production. In fact, methane can be used as fuel for energy generation or as feedstock for the production of CO and H 2 , used as reactants in several chemical processes [21][22][23][24][25].…”

Pilot Plant Data Assessment in Anaerobic Digestion of Organic Fraction of Municipal Waste Solids

et al. 2019

In this paper, a preliminary study of anaerobic digestion of organic fraction of municipal solid wastes (OFMSW) in presented with the aim to compare the performances of both wet- and dry-type reactors. The treatment of OFMSW via anaerobic digestion (AD) producing biogas is a process that is receiving a growing interest because two different needs can be coupled: the request of sustainable municipal waste treatments and increasing demand renewable energy. This paper aims to offer experimental results comparing batch test and continuous experimental reactors under different conditions of humidity and solid content. Results show that both the investigated configurations may be used for converting OFMSW into a high quality biogas and that the increase of dry matter in the continuous process still allows to achieve significant biogas production rates. A slight reduction of the methane content was observed (less than 5% relative) that can be also related to the change in the level of volatile fatty acids. These results are very promising in supporting the possibility of operating an industrial scale plant with a dry-process without affecting the system performance.
