Towards a complete characterisation of guaiacwood oil

Authors: Loïc Tissandié, Stéphane Viciana, Hugues Brevard, Uwe J. Meierhenrich, Jean-Jacques Filippi Abstract Guaiacwood oil is a common perfume ingredient used in modern compositions for its suave woody-rosy scent. This essential oil is a byproduct of the timber industry obtained by hydrodistillation of the heartwood of Bulnesia sarmientoi, a tree native from Latin America. Despite being widely used in perfumery, guaiacwood oil has been …

Catalytic conversion of beech wood pyrolytic vapors

Authors: Alexandre Margeriat, Alissa Bouzeggane, Chantal Lorentz, Dorothée Laurenti, Nolven Guilhaume, Claude Mirodatos, Christophe Geantet, Yves Schuurman Abstract Catalytic fast pyrolysis (CFP) of beech wood chips was undertaken in a laboratory-scale fixed bed reactor equipped with a biomass semi-continuous dispenser. During pyrolysis, chars are retained on a quartz frit and the pyrolytic vapors are entrained …

Co-processing of pyrolisis bio oils and gas oil for new generation of bio-fuels: Hydrodeoxygenation of guaı ̈acol and SRGO mixed feed

Authors: Stylianos D. StefanidisKonstantinos, G. Kalogiannis, Angelos A. Lappas Abstract Pyrolysis oil from lignocellulosic biomass (bio‐oil) is a promising renewable energy carrier that can be utilized for the production of second‐generation drop‐in biofuels. Co‐processing bio‐oil with petroleum feeds in existing refinery processes, such as fluid catalytic cracking (FCC), has been proposed as a cost‐effective way …

Valorization of coffee silverskin industrial waste by pyrolysis: From optimization of bio-oil production to chemical characterization by GC × GC/qMS

Authors: Allan dos Santos Polidoro, Enelise Scapin, Eliane Lazzari, Aline Nunes Silva, Anaí Loreirodos Santos, Elina Bastos Caramão, Rosângela Assis Jacques Abstract Coffee bean tegument (silverskin) is a by-product derived from the coffee roasting process. This residue has been discarded, which constitutes a serious environmental problem. The depletion of oil reserves and environmental issues promoted …

Supported oxides catalysts for the dehydration of isobutanol into butenes: Relationships between acidic and catalytic properties

Authors: Z. Buniazet, C. Lorentz, A. Cabiac, S. Maury, S.Loridant Abstract H4SiW12O40 heteropolyanions, WO3, TiO2 and SnO2 were supported over SiO2 at high loading by wet impregnation or grafting methods and evaluated in the dehydration of isobutanol to butenes. Their structural and textural properties were determined by different techniques such as XRD, TEM, IR, XPS and N2 liquid physisorption respectively. …

Integrated analyses of the transcriptome and metabolome of the leaves of albino tea cultivars reveal coordinated regulation of the carbon and nitrogen metabolism

Authors: Qunfeng Zhang, Dandan Tang, Meiya Liu, Jianyun Ruan Abstract Previous studies have revealed that dramatic changes in metabolism occur in albino tea leaves compared with regular green tea leaves. In particular, the flavonoid content decreased while the amino acid content increased notably, indicating that both the carbon and nitrogen metabolism had undergone significant changes. …

Naphthenic acids in oil sands process waters: Identification by conversion of the acids or esters to hydrocarbons

Authors: Michael J. Wilde, Steven J. Rowland Abstract Concerns over the toxicity associated with ‘naphthenic’ acids (NA) within oil produced waters and oil sands process waters (OSPW), whether justified or not, have increased the need for the structural elucidation of NA. Certainly, oil sands mining operations, such as those in Alberta, Canada, result in the …
