This work provides insights into the relationship between pyrolysis products distribution and structural features of xylose-based hemicelluloses. Three hemicelluloses differing in composition, molecular weight, chain branching origin were selected, structurally characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis nuclear magnetic resonance then used as feedstocks...

Abstract Corncob waste is not managed properly has the potential to environmental pollution. The purpose of this reasearch utilize corncob as a biomass into bioethanol. Process making bioethanol carried out in 4 steps, namely delignification, hydrolysis, fermentation, distillation. substrate were prepared mechanically become size powder 40 mesh. Delignification by fungi Dekkera Bruxellensis was...

Smoking is one of the efforts to maintain quality smoked fish. Phenol compounds in smoke can act as natural antioxidants inhibit lipid oxidation. Milkfish have a high content after protein, which undergo oxidation during processing and storage. The aim this study was observe effect antioxidant activity on different smoking methods storage time for 28 days at freezing temperature milkfish. Corn ...

Abstract Corncob pyrochar activated with steam (CCA) and nonactivated corncob (NCC) were produced characterized. The performance of the best material was tested in a dual‐chambered microbial fuel cell (MFC) as an electrode for bioelectricity generation using wet torrefaction wastewater substrate. Pyrolysis 80.3 g dried corncobs carried out at 600°C under constant N 2 flow 3 L min −1 30 resultin...

This paper presents results obtained from corncob combustion in a pilot scale vortexing fluidized bed combustor (VFBC). Three combustion modes including direct combustion, staged combustion and flue gas recirculation (FGR) combustion were employed, and their combustion and pollutant emission characteristics were studied. In addition, the effects of combustion fraction and bed temperature on pol...

Abstract Considering the expected increasing demand for cellulose fibers in near future and that its major source is wood pulp, alternative sources such as vegetable wastes from agricultural activities agro-food industries are currently being sought to prevent deforestation. In present study, was successfully isolated six agroindustrial residues: corncob, corn husk, grape stalk, pomegranate pee...
