Pyrolysis of Yellow Passion Fruit Peel Waste: A Route to Bio-Oil and Value-Added Chemicals.

Defect Engineering of Disordered Carbon Anodes with Ultra-High Heteroatom Doping Through a Supermolecule-Mediated Strategy for Potassium-Ion Hybrid Capacitors

Highlights The N/S co-doped lignin-derived porous carbon (NSLPCs) with ultra-high heteroatom doping was prepared through a novel supramolecule-mediated pyrolysis strategy. Covalently bonded graphitic carbon/amorphous carbon intermediates in...

Synergistic Effects and Kinetic Analysis in Co-Pyrolysis of Peanut Shells and Polypropylene

The impact of COVID-19 has boosted growth in the takeaway and medical industries but has also generated a large amount of plastic waste. Peanut shells (PS) are produced in large quantities and are challenging to recycle in China. Co-pyrolys...

Integrated geochemical evaluation of hydrocarbon source potential in late quaternary sediments of the Nkhata basin, Malawi

Abstract The Nkhata basin located in the central part of the Malawi rift consists of Late Quaternary (Chibanian to present;  6.02 wt% and S2 > 25.55 mg HC/g rock; 1 C: TOC up to 6.16 wt%, S2 up to 56.9 mg HC/g rock). The sediments were domi...

Pyrolysis and Pyrolysis Reoxidation Combustion Characteristics of Lignite

Coal, as the main energy source for building heating in northern cities of China, features large reserves, low cost, and high stability in heat supply. Low-temperature pyrolysis reactions are prone to occur within the coal pile; the coal af...

The Effect of Time on the Activation of Bayah Natural Zeolite for Application of Palm Oil Shell Pyrolysis

Oil palm shell (OPS) constitutes 60% of the waste generated during the processing of palm oil. However, OPS can potentially be converted into energy and chemicals through pyrolysis. The purpose of this study is to determine and analyse the ...

Correlation between molar concentration and properties of sprayed copper oxide thin films

Copper oxide precursor solutions containing 0.10 M, 0.15 M, 0.20 M and 0.25 M concentration of copper were deposited on a glass substrate using the spray pyrolysis method. The structural, optical and surface properties of the resulting copp...

Study of the red lacquer from a pair of Namban stirrups by Py-GC/MS

Oriental lacquer is a material of vegetal origin that is used in the Asian countries as a coating for the most varied kinds of religious and civil use objects. With the Portuguese arrival to the East, the Europeans started to develop a tast...

Unraveling the formation mechanism of 3-methylindole from tryptophan in the glucose-mediated Maillard reaction: a combined ReaxFF MD, DFT, and experimental study

3-Methylindole is a concentration-dependent aroma compound, and its formation mechanism in the tryptophan-glucose Maillard reaction is crucial for flavor regulation but remains incompletely elucidated. Using gas chromatography-olfactometry-...

Comparative Study for Selective Lithium Recovery via Chemical Transformations during Incineration and Dynamic Pyrolysis of EV Li-Ion Batteries

Selective leaching of Li from spent LIBs thermally pretreated by pyrolysis and incineration between 400 and 700 °C for 30, 60, and 90 min followed by water leaching at high temperature and high L/S ratio was examined. During the thermal pre...
