Summary: In this study, high-performance catalysts containing copper carbide (CuxC) were prepared for the hydrogenolysis of renewable glycerol towards 1,2-propanediol (1,2-PDO). The synthesis of Cu(OH)2-Zn(OH)2 mixture in a microchannel reaction system yielded highly dispersed precursors, and the addition of ZnO improved the dispersion of copper species with enhanced acidity. Copper carbide composite catalyst (Cu/Zn = 8) exhibited significantly higher hydrogenation activity and contributed to enhanced catalytic activity for continuous glycerol hydrogenolysis.

Summary: The production of 1,2-propanediol is facing significant challenges in the chemical industry due to the increasing demand and environmental regulations. The traditional method is energy intensive, therefore sustainable routes using renewable raw materials are becoming more attractive. This perspective reviews the current research and patents on 1,2-propanediol production, discussing alternative pathways, such as glycerol hydrogenolysis and biotechnological methods, and modern methods like chromium-free catalytic systems and multifunctional catalysts. Biobased 1,2-propanediol has the potential to replace traditional petroleum-derived 1,2-propanediol with environmental and economic benefits.

Summary: The hydrogenolysis of biomass-derived glycerol to produce 1,2-propanediol was investigated using transition metal catalysts supported on dolomite. Among the catalysts tested, Cu/Dol catalyst exhibited the best performance due to the interaction between copper species and dolomite, leading to high glycerol conversion and high selectivity for 1,2-propanediol with low methanol by-product formation.

Summary: The study reported a series of copper-loaded magnesium-aluminum-gallium oxide catalysts prepared by wet impregnation method, where gallium was found to have significant effects on the final catalysts. The catalytic activity of copper was identified as crucial for glycerol hydrogenolysis, with lower copper loading showing higher selectivity to 1,2-propanediol due to highly dispersed particles and sufficient amount of basic and acido-basic sites. The optimized reaction conditions for glycerol conversion were systematically investigated, including copper loading, Mg/Al/Ga ratios, reaction temperature, hydrogen flow rate, glycerol concentration, and weight hourly space velocity, further establishing stability, reusability, and structure-activity correlation of the catalyst.

Summary: The successful synthesis of finely tuned Ni1.5Sn nanoalloy phases from a mixed-metal zeolitic imidazolate framework (MM-ZIF) and its catalytic performance in the production of 1,2-propanediol (1,2-PDO) were investigated. The results demonstrated that the synergy between Ni-Sn alloy, finely dispersed Ni metallic sites, and the Lewis acidity of SnOx species-loaded ZnO played a pivotal role in the high activity and selectivity of the catalyst.

Summary: Glycerol conversion to 1,3-propanediol is an economical and sustainable approach, but traditional catalytic reactions often result in the production of 1,2-propanediol. Currently, tungsten-containing bifunctional catalysts are considered as highly effective and atom-economical catalytic systems for selectively hydrogenolysis of glycerol to 1,3-propanediol.

Summary: The hydrothermal treatment of pure silica Beta zeolite supported copper species (Cu/Si-Beta-HT) has been found to be highly efficient for the catalytic conversion of glycerol to 1,2-propanediol, achieving a conversion rate of 96.0% and selectivity of more than 99.9%. The high dispersion of Cu nanoparticles in the catalyst is confirmed by TEM images and N2O titration experiments. Pyridine-adsorption FTIR spectra and NH3-TPD profiles suggest the presence of copper species as Lewis acidic sites in the catalyst. The hydrogenolysis of glycerol to 1,2-propanediol involves the dehydration of glycerol to acetol and the hydrogenation of acetol to 1,2-propanediol, catalyzed by copper cations and Cu nanoparticles, respectively. In situ FT-IR spectra and kinetic studies indicate that the dehydration step is slower than the hydrogenation step and is a key process for this reaction.

Summary: Cu-Ni / xMgO-Al2O3 catalysts were used for the hydrogenolysis of glycerol to produce 1,2-propanediol without the addition of external hydrogen. The addition of MgO to alumina improved the yield of 1,2-propanediol. The rate limiting step for MgO-Al2O3 catalysts is the hydrogenation of acetol, while Cu-Ni / MgO catalysts follow a basic route.

Summary: In this study, HZSM-5 supported bimetallic Ru-Cu catalysts were used to convert glycerol from biodiesel production into propanediols through the hydrogenolysis reaction. The catalysts were characterized using physisorption analysis, XPS analysis, and chemisorption analysis. It was found that the bimetallic catalysts showed an improvement in selectivity to propanediols, although they had lower activity and reaction's TOF compared to the monometallic catalysts. The results indicate that Ru dilutes Cu and the interaction between Ru and Cu plays a crucial role in the catalytic performance.

Summary: The study investigates Ruthenium-copper bimetallic catalysts supported on modified zirconia for the hydrogenolysis of glycerol to produce 1,2-propanediol. The addition of copper to the Ru-based catalysts resulted in decreased glycerol conversion and increased selectivity to 1,2-propanediol. The best performing catalyst was bimetallic Ru-Cu/m-ZrO2, while catalysts supported on 3%SO4-ZrO2 showed lower activity likely due to sulfur poisoning. Addition of Cu to Ru led to site blockage and tuning of selectivity towards C-O cleavage.

Summary: This study explores the techno-economic feasibility of using glycerol to produce propanediols. Selective hydrogenolysis of glycerol can produce 1,2-propanediol, while microbial fermentation of glycerol can produce 1,3-propanediol with the co-production of 2,3-butanediol and ethanol. Process integration reduces utility demands, but utilities are still major operating costs. The production cost of 1,3-propanediol by batch fermentation is higher than that of 1,2-propanediol, while fed-batch fermentation of microbial 1,3-propanediol is economically viable.

Summary: A membrane-assisted stirred slurry reactor was developed by introducing a membrane tube into a stirred tank, and simulations using Euler-Lagrange method showed good agreement with experimental data on cake mass and particle deposition patterns. The presence of the membrane tube created an asymmetric flow field, with shear stress on the membrane surface directly affecting particle deposition. Increasing impeller speed reduced particle deposition, and positioning the membrane tube close to the impeller decreased cake mass. Upward liquid flow from a pitched-blade impeller resulted in lower shear stress, making a vertical-blade impeller preferable.

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.
