“…Meanwhile, the yield started decreasing gradually after the molar ratio is increased to 1:5 and 1:6 ( Figure 7 b). Rafiei et al [ 38 ] used CRL@ZIF-67 in biodiesel production and achieved the highest conversion when the oil/alcohol molar ratio was 1:6.…”

A hierarchical mesoporous zeolitic imidazolate framework (ZIF-8) was processed based on cetyltrimethylammonium bromide (CTAB) as a morphological regulating agent and amino acid (l-histidine) as assisting template agent. Burkholderia cepacia lipase (BCL) was successfully immobilized by ZIF-8 as the carrier via an adsorption method (BCL-ZIF-8). The immobilized lipase (BCL) showed utmost activity recovery up to 1279%, a 12-fold boost in its free counterpart. BCL-ZIF-8 was used as a biocatalyst in the transesterification reaction for the production of biodiesel with 93.4% yield. There was no significant lowering of conversion yield relative to original activity for BCL-ZIF-8 when continuously reused for eight cycles. This work provides a new outlook for biotechnological importance by immobilizing lipase on the hybrid catalyst (ZIF-8) and opens the door for its uses in the industrial field.

“…Application of other types of metal-based catalysts particularly MOFs in this field were rarely reported. These types of catalysts have showed great results in other research areas such as production of biodiesel (Rafiei et al, 2018 ), due to their physico-chemical characteristics (e.g., large surface area and porosity), and their applications should be accelerated in the glycerol acetalization reaction.…”

The last 20 years have seen an unprecedented breakthrough in the biodiesel industry worldwide leads to abundance of glycerol. Therefore, the economic utilization of glycerol to various value-added chemicals is vital for the sustainability of the biodiesel industry. One of the promising processes is acetalization of glycerol to acetals and ketals for applications as fuel additives. These products could be obtained by acid-catalyzed reaction of glycerol with aldehydes and ketones. Application of different supported heterogeneous catalysts such as zeolites, heteropoly acids, metal-based and acid-exchange resins have been evaluated comprehensively in this field. In this review, the glycerol acetalization has been reported, focusing on innovative and potential technologies for sustainable production of solketal. In addition, the impacts of various parameters such as application of different reactants, reaction temperature, water removal, utilization of crude-glycerol on catalytic activity in both batch and continuous processes are discussed. The outcomes of this research will therefore significantly improve the technology required in tomorrow's bio-refineries. This review provides spectacular opportunities for us to use such renewables and will consequently benefit the industry, environment and economy.

Summary The present work investigates the synthesis of a new and highly efficient sodium‐doped nanohydroxyapatite, as a heterogeneous catalyst for the production of fatty acid methyl esters from Schizochytrium algae oil. Sodium nitrate supported on nanohydroxyapatite catalyst was prepared using wet impregnation technique and calcinated at different temperatures. The synthesized nanocatalyst was characterized to determine the structural and morphological properties, using BET, XRD, TGA, FTIR, ICP, and TEM. Characterization results reported that the catalyst calcinated at 900°C exhibits good catalytic property. The catalyst was utilized for the production of biodiesel, under different reaction parameters through transesterification process. Response surface methodology (RSM) and artificial neural network (ANN) were employed to evaluate the best combination of molar ratio, catalyst concentration, and reaction time for transesterification process. By using point prediction method, the optimum yield of 96% was achieved at the catalyst concentration of 9.5 wt% of oil, 1:12 molar ratio, and 121‐minute reaction time. The physiochemical properties of the biodiesel were determined, and the result suggested that the biodiesel produced met ASTM D6751 standard. The catalyst exhibits good catalytic performance on reusability up to six runs without the loss of molecular activity. Therefore, the synthesized heterogeneous catalyst derived from animal bone could be efficiently used for the biodiesel production.
