Summary: In this study, Metal-Organic Framework MOF-5 was used for the first time as a heterogeneous acid catalyst for the simultaneous esterification/transesterification of two nonedible oils. The optimal reaction conditions for biodiesel production from waste cooking oil and Jatropha curcas oil were identified using a surface response methodology, with high yield conversions and decreased free fatty acid content. The produced biodiesel met the ASTM D6751 quality standard, and a cost analysis of biodiesel production was also provided.

Summary: Five heterogeneous catalysts (Ba(OH)(2), CaO, MgO, ZnO, and AlCl3) were used to produce biodiesel from waste cooking oil. The reaction parameters of each catalyst were optimized by studying the influence of catalyst loading, methanol-to-oil ratio, and reaction duration. The addition of acetone as a cosolvent increased the biodiesel yield, and all heterogeneous catalysts were found to be reusable, with Ba(OH)(2) and CaO showing significant yields until the third cycle.

Summary: The study aimed to develop a sustainable Ni/Zeolite catalyst derived from geothermal solid waste for waste cooking oil processing. By investigating the effects of catalyst concentration and operation temperature on transesterification process, the optimal conditions for biodiesel production from waste cooking oil were determined. Results showed that the synthesized Ni/Zeolite catalyst had granular shape, crystalline structure, increased surface area, and pore volume. Highest biodiesel yield was achieved at 3% w/w Ni/Zeolite catalyst addition and 60 degrees C operating temperature. The synthesized catalyst showed a decrease in biodiesel yield after three cycles of reuse.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
