This work focuses on the impact of carrier gas quantity and quality pyrolytic products received from intermediate pyrolysis brewer’s spent grain. In this study, three types gases were tested: argon, nitrogen, carbon dioxide at temperatures 500, 600, 700 °C. On basis process conditions, yield was determined. The ultimate analysis char performed, for selected chars, combustion properties Gas chro...

Laser-induced graphitization leads to screen printed highly oriented pyrolytic graphite electrodes.

Fast pyrolysis is an efficient technique for thermal degradation of lignin to bio-oils containing bio-phenols for the synthesis of adhesives, resins, and polymers. Lignin has a complex structure, and hence a large number of pyrolytic components are generated during the pyrolysis process. The composition of the pyrolytic products depends on the type of lignin, temperature, types of catalyst, and...

Pine sawdust pyrolysis was carried out respectively using microwave and conventional electrical heating at different temperatures in order to understand the properties of pyrolytic products from microwave pyrolysis of biomass. Less char material was obtained by microwave pyrolysis compared to conventional heating at the same temperature. While comparing the components of the pyrolytic gases, it...

Catalytic substrate, which is devoid of expensive noble metals and enzymes for hydrogen peroxide (H₂O₂), reduction reactions can be obtained via nitrogen doping of graphite. Here, we report a facile fabrication method for obtaining such nitrogen doped graphitized carbon using polyacrylonitrile (PAN) mats and its use in H₂O₂ sensing. A high degree of graphitization was obtained with a mechanical...

In a previous work we studied the influence of heat treatment on the molecular sieve properties of activated carbons prepared by chemical activation of lignin [1]. The thermal treatment modified the porous structure of the activated carbons, giving rise to solids that separate C6H6 from C6H12, CO2 from CH4 and O2 from N2 with a relative high selectivity. However, the heat treatment drastically ...
