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.

In the process of biodiesel production, a significant amount glycerol, by‐product, is generated. This glycerol needs to be removed purify biodiesel. Hydrocyclones have been developed for efficient separation immiscible liquid–liquid systems. However, performance hydrocyclones operating with high levels liquid impurities requires further investigation. research aims examine impact hydrocyclone geometry on efficiency from Two types hydrocyclones, short‐tail and long‐tail, were studied. A computational fluid dynamics (CFD) model, based Eulerian–Eulerian two‐fluid model was used predict flow behavior within system. Detailed hydrodynamic in both long‐tail analyzed. Separation purity increased decrease volume fraction feed, an increase inlet velocity, or density. these conditions had minimal effect ratio. The exhibited higher compared hydrocyclone, although its ratio considerably lower. Therefore, purification investigated. It found that improved underflow outlet diameter overflow diameter. changes opposite Additionally, optimum configuration obtained.
