Summary: Biodiesel production has increasingly shifted towards using heterogeneous catalysts derived from biomass, due to their sustainability, economical and eco-friendly nature, ease of recovery, and the potential to eliminate biomass residues. The review discusses various biomass sources as precursors for heterogeneous catalysts, different methods for preparation, their advantages and drawbacks, as well as their performance in biodiesel production. The use of biomass ash or biochar-based catalysts shows promise in biodiesel synthesis, but requires improvements in catalyst load, reaction time, temperature, and methanol-to-oil ratio.

Summary: Recent studies have shown that microalgae hold potential for use in biodiesel synthesis. The use of heterogeneous catalysts and immobilized enzymes can simplify the synthesis process, reduce costs, and improve ester yields. Parameters such as temperature and molar ratio of alcohol to oil have significant effects on the yield under enzymatic catalysis conditions.

Summary: Biodiesel, a biofuel with multiple advantages over petroleum diesel, has seen significant growth in utilization from oil-bearing edible biomasses. However, due to increasing global prices, energy demand, and greenhouse gas emissions, edible feedstocks are not sustainable. Inedible biomasses, via catalyzed transesterification, have been proposed as potential feedstocks for biodiesel production. Nanocatalysts, favored for their easy separation and ability to retain catalytic activity, play a crucial role in biodiesel production due to their high efficiency. Nanocatalysts, such as zirconium oxide (ZrO2) and nano CaO, offer high biodiesel conversion rates and environmental friendliness. This review extensively discusses the significance of nanocatalysts in biodiesel synthesis, including reaction mechanisms, support and promoter functions, renewable feedstocks, synthesis routes, and characterization techniques. The review also covers kinetics, thermodynamics, process simulation, and optimization of heterogeneous nanocatalyzed biodiesel production. Ultimately, this review provides researchers with valuable information on developing cost-effective nanocatalysts for sustainable biodiesel production.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
