Cellulosic pine needles-based biorefinery for a circular bioeconomy

Bioresource Technology, Год журнала: 2022, Номер 367, С. 128255 - 128255

Опубликована: Ноя. 5, 2022

Pine needles (PNs) are one of the largest bio-polymer produced worldwide. Its waste, i.e., fallen PNs, is mostly responsible for forest fires and a major challenge. In present article, we have reviewed differenteffortsmadeto tackle this situation. PNs been used in various fields such asin composite, water purification industries,electronic devices, etc. Gasification appealing processes turning into bio-energy; pyrolysis technique has employed to create carbon-based materials; saccharification combined with fermentation good yields bio-ethanol; Pd or Ni/PNs biocatalyst showed catalytic properties variousreactionsand without catalyst an alluring prepare bio-fuel. Nano cellulose extracted from thermal mechanical strength. The air quality nearbyenvironment was examinedby studying magnetic PNs. Packing materials made exceptional ethylene scavenging abilities.

A Review on Metal–Organic Framework as a Promising Catalyst for Biodiesel Production

Energy & Fuels, Год журнала: 2024, Номер 38(4), С. 2654 - 2689

Опубликована: Фев. 2, 2024

The rapid depletion of fossil-derived fuels along with rising environmental pollution have motivated academics and manufacturers to pursue more environmentally friendly sustainable energy options in today's globe. Biodiesel has developed as an ecologically favorable alternative. However, the mass manufacturing biodiesel on industrial scale confronts substantial cost pricing challenges. To address this issue, high-efficiency catalysts a large number active sites are needed, resulting increased output quality. Metal–organic frameworks (MOFs) received lot interest catalyst for converting oils/fats or fatty acids into biodiesel. MOFs polyporous materials that can alter pore size well topological structure. They serve versatile foundation designing satisfy unique needs catalytic reactions conversion pathways. purpose current work is shed light underlying mechanisms essential properties MOF-based used synthesis. In addition, several methods connecting inside scrutinized, while usability production process completely compared other catalysts. More importantly, limits future research directions about utilization synthesis route also critically presented. general, review contributes improved awareness potential sector by investigating primary mechanism characteristics
