Summary: The study successfully validated a model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) using a LTA zeolite hydrophilic membrane. Experimental runs showed that the model accurately predicted the molar fractions of compounds in the reaction medium and their evolution over time. The partial separation of H2O from the reaction medium in the PBMR led to higher DME yield, CO and CO2 conversions compared to systems without membrane.

Summary: The direct conversion of syngas to methyl acetate (MA) via dimethyl ether (DME) was conducted in a combined fixed/fluidized bed reactor using Cu-ZnO-Al2O3 (CZA) and spray-dried ferrierite zeolite (SPD-FER) catalysts. DME synthesis occurred in a fixed bed at the bottom, while DME carbonylation proceeded in a fluidized bed at the top. The XCO decreased with increasing space velocity due to the transition from particulate to bubbling regime, affecting attrition and deactivation rate. The XCO decreased and XDME increased with higher molar fraction of CO, with higher values observed in the combined fixed/fluidized bed reactor compared to the fixed/fixed bed reactor. Additionally, the deactivation rate was higher in the combined fixed/fluidized bed reactor.

Summary: This study experimentally compares the performance of a packed bed membrane reactor (PBMR) and a conventional packed bed reactor (PBR) for CO2 conversion to dimethyl ether (DME). The PBMR outperforms the PBR in most conditions, with improvements in CO2 conversion and DME yield. Higher sweep gas-to-feed ratios increase water removal and improve PBMR performance, but result in the removal of other products. Higher temperatures selectively enhance the rWGS reaction but reduce DME yield due to methanol loss. Higher transmembrane pressures are not beneficial for PBMR performance. Reactor models developed in previous studies accurately describe the performance of both reactors and can be used for further optimization and simulation.

Summary: The direct hydrogenation of CO2 to dimethyl ether (DME) is a promising technology, and a 1D phenomenological reactor model was developed to optimize membrane reactor performance for this conversion. The study found that the circulation of a sweep gas stream through the permeation zone increased overall DME yield, and determined optimal membrane properties for reactor performance, considering non-ideal separation and non-isothermal operation. The membrane reactor demonstrated higher water removal efficiency and improved CO2 conversion and DME yield compared to a conventional packed bed, showing promising potential for CO2 valorisation.

Summary: Tantalum-oxy-nitride nanotubes (TaOxNy NTs) were synthesized through controlled anodic oxidation of metallic Ta foils followed by high-temperature annealing under NH3 flow. The length and inner tube diameter of the NTs were in correlation with the synthesis parameters. The conversion of Ta2O5 into TaOxNy influenced the absorption in the visible region, resulting in a bandgap shift. The TaOxNy NTs film-type electrode showed excellent photo-electrochemical and catalytic performances in various photo-reactions.

Summary: Designing CO2 methanation catalysts that meet industrial requirements is still challenging. We report Ni-Fe hydrotalcite-derived catalysts with a wide range of Ni and Mg loadings showing that an optimised composition with Ni0.4 gives a very high CO2 conversion rate of 0.37 mmol/gcat/s at 300 degrees C. This catalyst is studied by in-situ APXPS and NEXAFS spectro- scopies and compared with the other synthesised samples to obtain new mechanistic in- sights on methanation catalysts active for low-temperature (300 degrees C) methanation, which is an industrial requirement. Under methanation conditions, in-situ investigations revealed the presence of metallic Ni sites and low nuclearity Ni-Fe species at xN; L (Ni loading)=21.2 mol%. These sites are oxidised on the low Ni-loaded catalyst(xN;L=9.2 mol%). The best CO2 conversion rate and CH4 selectivity are shown at intermediate xN;L (21.2 mol%), in the presence of Mg. These superior performances are related to the high metallic surface area, dispersion, and optimal density of basic sites. The TOFCO2(turnover frequency of CO2 con- version) increases exponentially with the fractional density of basic to metallic sites (XB) from 1.1 s-1(xN;L=29.2 mol%) to 9.1 s-1(xN;L=7.6 mol%). It follows the opposite trend of the CO2 conversion rate. In-situ DRIFTS data under methanation conditions evidence that the TOFCO2at high XB is related to the presence of a formate route which is not predominant at low XB (high xN; L ). A synergistic interplay of basic and metallic sites is present. This con- tribution provides a rationale for designing industrially competitive CO2 methanation cat- alysts with high catalytic activity while maintaining low Ni loading.(c) 2023 Institution of Chemical Engineers.

Summary: Operando soft and hard X-ray spectroscopic techniques were used to investigate Zn-containing Cu nanostructured electrocatalysts in CO2 hydrogenation reaction. The study reveals that Zn is alloyed with Cu in the bulk of the nanoparticles, while low reducible Cu(I)-O species are consumed at the interface. The Cu-Zn system represents the optimal active ensembles with stabilized Cu(I)-O, which activates CO2 and supplies H atoms for the hydrogenation reaction.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
