“…Due to a variety of advantages such as less corrosion, convenient handling and separation, reusability and less amount of toxic wastes, heterogeneous catalysts are considered as efficient alternatives to homogeneous catalyst (10). Production of zeolite as a catalyst has increasingly improved in recent years (11). In general, zeolites are based on the structure of threedimensional network of an aluminum and silicon tetrahedral as TO 4 (T = Co, Fe, Si, B, Al, Ge, P) linked by shared oxygen atoms (12).…”

“…Cashew nuts with testa shell are also abundant in fatty acids, mainly oleic, linoleic, and palmitic acids (Trox et al 2010). The fatty acids from natural products are of particular interest because of their diverse biological activities and nutritional importance to human health (Jamil et al 2020). They play roles in numerous physiological processes, such as energy metabolism, cell signaling, and membrane structure (Chandrasekara and Shahidi 2011a).…”

The cashew agroindustry generates substantial by-products that are often improperly used. Cashew nut testa shell (CNTS) has attracted interest due to its elevated fatty acid contents and phenolic compounds, raising the relevance of environmentally friendly extraction techniques for its recovery. CNTS was submitted to high-pressure (Supercritical Fluid Extraction – SFE; Pressurized Liquid Extraction – PLE; and Subcritical Water Extraction – SWE) methods compared to traditional low-pressure (Soxhlet and maceration) techniques. Supercritical fluid extraction with CO2 as solvent was selective to recover fatty acids, such as palmitate (12.63 mg g-1), stearic (26.65 mg g-1), and oleic ( 25.61 mg g-1) acids, as well as behenic (46.42 mg g-1) and erucic (28.00 mg g-1), quantified by GC-MS. In contrast, the ethanolic and aqueous extracts, by pressurized liquid and subcritical water extraction, presented polyphenols like catechin, epicatechin, and procyanidin identified by UPLC-PDA-ESI-QDa, known for their high antioxidant potential and biological activities. In addition, fractions of proteins and sugars were also recovered. Considering the different compounds in the raw material, sequential extraction routes were conducted to fractionate the CNTS and provide different products from an underestimated raw material, a novelty that increased the value of the cashew processing chain.

“…However, the catalytic activity decreased after reusing three times. Other researchers used alumina [3,4], zeolite [5], and other metal oxide [6] based catalysts. The use of alumina ensures that the catalyst is still active even when using high freefatty acid feedstock [3].…”

This research investigated the performance of hematite-gamma alumina (Fe2O3/γ-Al2O3) catalyst in biodiesel production from palm oil. A full factorial experimental design was utilized to analyze the effect of hematite content, catalyst loading, and methanol-to-oil ratio on catalyst performance. From the experiment, biodiesel in the range of 73.6 to 87.6% FAME content was obtained. It was concluded that the catalyst composition, the methanol-to-oil ratio, and the catalyst loading have a significant effect on the FAME content of the biodiesel. Hematite has strong affinity for fatty acids, so a larger hematite surface area will result in a higher fatty acid absorption capacity. The addition of excess methanol can reduce the contact inhibition between the reactants and the active site of the catalyst, thereby increasing the conversion rate of the reaction. Moreover, a higher amount of catalyst loading can result in an increase in the FAME content when accompanied by an increase in the hematite content of the catalyst.
