Abstract The application of nanocatalysts for the conversion crude oil into biodiesel represents a promising strategy to mitigate environmental issues and diminish dependence on fossil fuels. This review scrutinizes contemporary developments in nanocatalyst technology pertaining synthesis, emphasizing effectiveness, specificity, ecological sustainability various nanocatalysts, which include metal oxides, magnetic solid catalysts, an array other nanostructured materials. These catalysts have exhibited substantial potential augmenting efficiency selectivity production, attributable their enhanced catalytic performance, extensive surface area, resilience saponification, rendering them appropriate diverse feedstocks such as recycled oils, animal fats, plant oils. Notwithstanding obstacles associated with production costs recycling procedures, recent progress economically viable manufacturing techniques sustainable recovery methods, including separation approaches, offers significant promise. A thorough lifecycle assessment (LCA) remains imperative appraise economic viability employing taking account parameters, raw material acquisition, energy utilization, waste generation. accentuates superior efficacy comparison traditional heterogeneous underscoring capacity expedite synthesis facilitate transition toward more environmentally paradigm.

Compression ignition (CI) engines are widely used in transportation and industry due to their reliability high thermal efficiency. On the other hand, use of CI coincides with emission harmful pollutants, address these problems, researchers were interested studying different types fuel additives, such as biodiesel, ethanol, nanoparticles. Generally, there increasing views that adding Nano-additives improves thermo physical properties helps enhance combustion characteristics. More so, investment Nano-fuel additives generally leads premature accelerated charge inside engine cylinder. What's more, optimal amount Nano is associated improvements characteristics reduced exhaust emissions. This review concentrated on recent advancements nanoparticles, specifically from Nanoparticles, a diesel additive, including experimental theoretical analyses. study's findings can contribute development more efficient environmentally friendly technology. Finally, potential mechanisms underlying also reviewed discussed.

This study aims to enhance local bentonite's effectiveness in removing methylene blue and procion deep red dyes from aqueous media through organic modification with cetyltrimethylammonium bromide surfactant. Raw modified bentonites were analyzed using XRF, XRD, FTIR, BET/BJH, DSC techniques. The bentonite showed a crystalline structure mesoporous morphology heterogeneous surface. Optimal adsorption conditions for MB dye 0.2 g adsorbent dose, 60 min contact time, mg/L initial concentration, pH 8, achieving maximum sorption capacity of 6.418 mg/g. For PDR dye, optimal 0.125 40 30 acidic pH, 8.503 Isotherm analysis indicated the Langmuir model best fits data, suggesting mono-layer process. Kinetic investigations revealed that follows pseudo-second-order model, indicating chemisorption mechanism. Thermodynamic results exothermic endothermic PDR. work highlights potential surfactant-modified as cost-effective sorbent treating polluted systems, effectively both cationic anionic dyes.

Improvement in biofuel synthesis technology could facilitate widespread utilization of biodiesel, and an efficient operation terms cost. Catalyst enhancement through mineralization waste biogenic material is vital for biodiesel production. In this study, production was from cooking oil (WCO) using a bifunctional catalyst synthesized eggshells ferric sulfate. The CaO precursor developed calcined eggshell at 800 °C 3 h impregnated with sulfate ratio 1:1. Bifunctional characterized X-ray diffractometer, scanning electron microscopy, Fourier transform infrared spectroscopy energy-dispersive analysis. applied one-pot reaction WCO methanol to produce biodiesel. modeled the Taguchi orthogonal array design maximize heterogeneous contained Ca (20.7 %), Fe (18.5 S (4.5 O (54.8 %). identified crystalline phases are CaSO4/Fe2O3 CaSO4.0.5H2O/Fe2O3. A maximum yield 89.94 wt% observed under operating conditions methanol/oil molar 5:1, time 45 min, temperature 70 °C, amount 4 wt%. reusability established (four) cycles without further treatment. met standard specifications. Hence, proved effective transesterification moderately high free fatty acid, thereby expedite oil, serve as fuel powering diesel engines.
