The present work reports a theoretical study of the infrared spectra chemical structures that are suitable to description surface chemistry carbon materials. Prior any consideration, computational approach was tested and adapted by comparing predicted IR those obtained experimentally for various reference compounds. Several models were considered, subsequently accounting most relevant functional groups have been postulated decorate edges graphene layers on materials (i.e., anhydrides,...

Residual biomass is a valuable and growing by-product, but often underutilized. This research aims to investigate the possible strategies for energetic valorisation of agri-food industry wastes: grape seed chestnut shell. Pyrolysis thermal process was selected this work. Applied biomass, pyrolysis promising method simultaneous production biochar, bio-oil, gas. Two different processes were conducted: conventional at 750 °C flash 850 °C. Flash yielded superior product properties compared...

Herein we report results from quantum chemical calculations on a large series of pyrone-like model compounds which are relevant for carbon basicity. In consonance with previous work (Carbon 1999, 37, 1002), functionalities at the edge graphene layers predicted to exhibit broad range pKa values (4−13) depending relative position ketone and etheric rings. The thermodynamic stability pyrones is discussed in terms reaction energies calculated selected isodesmic processes give insight into role...

The use of sewage sludge as a precursor adsorbent/catalyst materials for environmental applications has been encouraged during the past few years. Due to heterogeneous nature sludges, there exists lack information regarding characteristics these low-cost precursors and how their physicochemical properties affect final performance prepared from them. In this work, three sewage-sludges collected at WWTPs with assorted sludge/wastewater treatment schemes were used adsorbents/catalysts H2S...

The textile industry generates millions of tons waste annually, making this sector one the most polluting in world. objective research was to study energy potential three industrial wastes vegetable and animal origin: CW (card waste), SFW (short fibre waste) W (wool), using conventional flash pyrolysis at 500 °C 750 °C. thermogravimetric profiles were very different from W. In general, bio-oil yield higher low-temperature (up 55 %). gas obtained by has flue content lower CO2 so their high...

Green and Sustainable activated carbons were obtained by one-step alkaline chemical activation process using a food industry lignocellulosic waste (pomegranate peels) as precursor. A non-harmful activating agent (alkali carbonate) was used, more sustainable alternative to alkali hydroxides. The pomegranate peels-based present high carbon content (>94%), low ash (<0.5%) significant nitrogen (>1.0%); this last value is important because they can be highly effective CO2 adsorbents with the aim...

The contribution to carbon basicity of π−cation interactions in aromatic systems has been investigated this work by carrying out ab initio calculations on various cluster models. According levels theory, the mono-, bi-, and tridentate H3O+−benzene complexes present a binding enthalpy gas phase about −28 kcal/mol showing intermolecular contact through unconventional hydrogen bonding between H3O+ π-cloud benzene. interaction energies calculated for other models (pyrene−benzene−H3O+,...

The present paper discusses H2S removal by a new generation of sewage-sludge-derived materials which are characterized their outstanding textural properties when compared to previous obtained pyrolysis and/or activation similar precursors. Alkaline hydroxide was used prepare adsorbents/catalysts covering wide range porosities (SBET values from 10 1300 m2 g-1). Our results outline that important for abatement. However, not only highly porous sorbents, but also high metallic content and basic...
