Corn cob pyrolysis: A systematic literature review of methods and applications
The Canadian Journal of Chemical Engineering, EarlyView.Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

ChemPhysChem, EarlyView.Bi/BiOBr/P25 TiO2 composites are synthesized via a solvothermal method incorporating 1 wt% of a carbon‐based material (graphene oxide [GO], graphene, carbon nanotubes, or buckminsterfullerene). The GO–based composite exhibits the highest photocatalytic NOx removal efficiency (≈22% NO and ≈15% NO2) with these synergetic improvements attributed to ...

Aspects of structural features in lignite and lignite humic acids
Fuel Processing Technology, 2006 Abstract Structural features of a South Moravian lignite and its humic acid (HA) fraction were studied by means of UV–vis, 1 H and solid-state 13 C NMR, and FT-IR spectroscopy in addition to basic elemental analyses. The structural differences between the original lignite and its HA-type fraction were relatively minor, and their unambiguous ...

Study on the Water in Lignite by DSC
MATEC Web of Conferences, 2017 As pointed out in several previous works, new drying technologies must be developed to ensure lignite remained competitive. In order to design and test them, it was needed to have a better understanding of the characters of water in lignite.
