“…Catalysts 2019, 9, x FOR PEER REVIEW 20 of 39 evidenced that zeolites or ferrierite could effectively mitigate the influence of water and avoid catalyst sintering [89,90]. In a fixed bed reactor, kinetic modeling confirmed the negative effect of water (formed during the reaction process) on DME production, which is consistent with the experimental results.…”

“…Kansai Electric Power Co. and Mitsubishi Heavy Industries have realized a bench-scale (100 cm 3 catalyst loading) experiment for DME synthesis [87,88]. However, during the reaction process, water formation decreased the yield of DME [89][90][91]. Catizzone et al and Bonura et al evidenced that zeolites or ferrierite could effectively mitigate the influence of water and avoid catalyst sintering [89,90].…”

Due to the increasing emission of carbon dioxide (CO2), greenhouse effects are becoming more and more severe, causing global climate change. The conversion and utilization of CO2 is one of the possible solutions to reduce CO2 concentrations. This can be accomplished, among other methods, by direct hydrogenation of CO2, producing value-added products. In this review, the progress of mainly the last five years in direct hydrogenation of CO2 to value-added chemicals (e.g., CO, CH4, CH3OH, DME, olefins, and higher hydrocarbons) by heterogeneous catalysis and plasma catalysis is summarized, and research priorities for CO2 hydrogenation are proposed.

“…e high activity of ferrieritebased catalysts was also found for bio-syngas or CO 2 onepot conversion to DME [22,23]. In particular, Bonura et al report that deactivation of ferrierite-based catalyst depends on both acidity and the crystal size of zeolite [24]. Nevertheless, a very little attention has been paid to investigate the catalytic behaviour of hierarchical FER zeolite.…”

In contrast to high silica zeolites, it is difficult to obtain mesoporosity in zeolites with low Si/Al ratio (e.g., <20) via conventional NaOH-based treatment, making the obtainment of hierarchical zeolites with high acidity a challenging target. In this paper, we report the preparation of hierarchical FER-type zeolite at low Si/Al molar ratio (about 10) by postsynthesis etching involving a sequence of three treatments with NaAlO 2 , HCl, and NaOH solutions and investigate the effect of both NaAlO 2 solution concentration and time of treatment on the textural properties. e obtained materials exhibit a mesoporous volume higher than the parent ferrierite with no significant effect on the sample acidity. e catalytic activity of some samples was investigated in vapour-phase methanol dehydration to dimethyl ether, revealing the superiority of hierarchical zeolites in terms of methanol conversion, although the presence of mesopores causes formation of light hydrocarbons at high temperatures.

“…In these conditions, the reported conversion of CO 2 reached 19% and selectivity to DME 8.6%. Change of the acid component to FER (Si/Al = 8) (240 °C, 3 MPa, GHSV = 8800 NL/g kat h) leads to slightly decreasing conversion of CO 2 (17%) and increasing selectivity to DME (42%) [38]. The most efficient catalyst (CZ citric +HPW-K10) shows 47% selectivity to DME and 5% CO 2 conversion.…”

Dimethyl ether (DME) is considered as a substitution of diesel oil. It can be used in diesel engines because of its high cetane number (> 55). The combustion process does not generate particle matter (PM) or sulphur oxides (SO x) pollutions. One of the methods to obtain DME is direct synthesis from a CO 2 and H 2 mixture. On the other hand, CO 2 is an attractive reagent, which is a safe and economical source of carbon. The aim of this work was to obtain DME in the direct process from the mixture CO 2 and H 2 in the presence of hybrid catalyst. In these catalytic the CuO/ ZrO 2 was selected as a metallic function. The montmorillonite K10 modified by heteropolyacids was selected as an acidic function. The catalysts were obtained by different preparation methods and contained various types of heteropolyacids. The catalysts were characterized by following methods: BET/BJH, XRD, SEM, DCS/ TG, NH 3-TPD and FT-IR. The direct hydrogenation of CO 2 was performed in the high pressure fixed-bed flow reactor connected online with GC equipped with TCD and FID detectors. It was shown that both synthesis method of metallic function and the type of heteropolyacids have influence on the total catalytic activity of the hybrid catalyst. The acidity and thermal stability of HPAs are identified as the most important parameters having a decisive influence on the overall catalytic activity of the samples.
