Biodiesel is a renewable and environmentally friendly alternative to fossil fuels. Despite nearly 3 decades of research in the field of biodiesel, there remains major obstacles for large-scale production. In the search for an active, selective, and reusable solid base catalyst, strontium oxide (SrO) is emerging out as a preferred choice for the transesterification reaction under various methods of activation. SrO exhibits the highest activity among processable alkaline earth metal oxides as a result of its strong basicity. SrO nanoparticles (NPs) and hybrids showed improved performance. Recent progress achieved in the development of synthetic methods of SrO NPs is reviewed. Advantages of SrO-based nanocomposites for biodiesel production are discussed. Finally, potential support materials for enhancing the catalytic performance of SrO NPs with commercial implications are elaborated.

“…For heterogeneous catalysts, the catalytic activity is affected by the surface area of the catalyst (Balajii and Niju 2019). The nitrogen adsorption evaluation was carried out to estimate the Brunauer-Emmett-Teller (BET) surface area (Sahani et al 2020). The BET results for NaOH/NaX catalyst (Fig.…”

In this research, Capparis spinosa oil was used as a feedstock for biodiesel production in the presence of NaOH/NaX as a nano heterogeneous catalyst. The NaOH/NaX catalyst was characterized by XRD, SEM, and BET analyses. The transesterification reaction was optimized through response surface methodology (RSM) based on the central composite design (CCD) of experiments. The effects of key variables of catalyst weight, methanol to oil molar ratio, and time on the reaction were studied, and a precise discussion about the impact of each process variable on the biodiesel yield was carried out. The highest biodiesel yield was 90.33% for the optimum reaction conditions that include a constant temperature of 60 °C, methanol to oil molar ratio of 6.7:1, catalyst weight of 2.3 wt%, and reaction time of 1.24 h. Furthermore, all physicochemical properties of the produced biodiesel were matched to the ASTM standard. Based on the obtained results, Capparis spinosa oil is a suitable source for biodiesel production.

“…non-toxic to the equipment(Chen et al 2020), easily separable from the biodiesel product, which improves biodiesel quality and reduces post-treatment cost (Naik and Meivelu 2020). heterogeneous base catalyst is more e cient than heterogeneous acid catalyst as they catalyze the reaction 4000 times faster than heterogeneous acid catalyst (Sahani et al 2020). the major drawback of heterogeneous catalysts is that it requires high temperature and pressure for acidic heterogeneous catalysts, low acid value feedstock for basic catalysts, and high cost for immobilized enzymatic catalysts(Khandan and Saffarzadeh-Matin 2020).…”

Biodiesel has recently received widespread attention as an essential source of renewable and environmentally friendly energy due to its ease of production and clean burning. Cashew nutshell is a biomass waste readily available in India. This work studies the production of fatty acid methyl ester (FAME) from the cashew nut shell liquid (CNSL) using sulfonated cashew nutshell biochar catalyst by transesterification reaction. Catalyst efficiency is compared with a conventional catalyst for biodiesel production. Characterization of the catalyst was done using FTIR, TGA, elemental analysis, and BET. Transesterification studies were carried out using KOH and the biochar catalyst. These studies inferred that the highest conversion of CNSL to FAME is achieved by using the conventional catalyst KOH (94.2% yield) and process parameters of 650C reaction temperature, 1hr reaction time, 18:1 methanol to oil ratio, and 5 w/w % catalyst weight. The highest conversion achieved using the biochar catalyst was 43.4% at optimum process parameters. The study revealed the feasibility of producing FAME from waste biomass, which lowers production costs and benefits environmental sustainability.
