“…It has been frequently used for the analysis of pyrolysis oils ( Li et al, 2017 , Chen et al, 2021 ). For a comprehensive overview of further analytical techniques for the characterization of complex pyrolysis (bio) oils including solvent fractionation techniques and volumetric methods, the reader is referred to the recent review of ( Staš et al, 2020 ).…”

“…15,16 More advanced techniques like nuclear magnetic resonance (NMR), high performance liquid chromatography (HPLC) or Fourier transformed infrared (FTIR) spectroscopy are known to provide valuable information on the quantification of specific functional groups in bio-oils. 17 Ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR/MS) has the capability of making a great impact in the analysis of highly complex and heavy feedstocks like heavy crude oil-derived mixtures, 18,19 or oxygenated streams. 13,20 Through this technique, the analysis of highly polar species (like those in bio-oil) is plausible using electrospray ionization (ESI), while the non-polar hydrocarbons and neutral phenolics are preferentially ionized through atmospheric pressure photoionization ((+)APPI).…”

Biomass pyrolysis liquids (bio-oils) unavoidably require catalytic hydrodeoxygenation (HDO) for their upgrading and stabilization for commercial usage. The complex composition of bio-oil constrains the fundamental kinetic understanding of the HDO. Here, we propose a multi-technique methodology to compositionally assess the complete spectrum of the HDO reactants and products, and then use it to pre-evaluate different catalysts in the HDO of a raw bio-oil obtained from black poplar. The used techniques are: micro chromatography (GC), GC with mass spectrometry (MS), bidimensional GC×GC/MS, elemental analysis, gel permeation chromatography, Karl-Fischer, thermogravimetric analysis, as well as Fourier ion cyclotron resonance mass spectrometry (FT-ICR/MS) using different ionization sources (ESI and APPI). The latter technique allows for the assessment of the heaviest and most refractory oxygenates in bio-oil, which have a pivotal role in the HDO catalyst performance. Three activated carbon-supported catalysts based on PtPd, NiW and CoMo mixed with a commercial HZSM-5 zeolite were used. We have been able to evaluate the multiple facets of catalyst performance: production of gases, catalytic coke, thermal lignin and most importantly, the aqueous and organic product fractions (hydrodeoxygenation of heavy species and production of light aromatics). The results of the detailed analysis methodology highlight their potential for the understanding of the HDO mechanism and for a detailed catalyst screening.

“…Ele pode ser facilmente armazenado, transportado e empregado como combustível líquido ou diesel e aplicado em diversos fins como: fornos, caldeiras e motores para produção de calor e energia (POKORNAet al, 2009). Além disso, o produto líquido pode ser destinado para produção de (i) adesivos; (ii) resinas; (iii) açúcares anidro, como o levoglucosan, que é utilizado na fabricação de fármacos (STAŠ et al, 2020); (iv) surfactantes; (v) polímeros biodegradáveis; (vi) em substituição ao fenol petroquímico ou (vii) fracionado para dar origem a novos produtos químicos (fertilizantes, ácidos, etc.) (BUet al, 2012).…”

Existem várias técnicas para o aproveitamento do lodo de esgoto, embora nem todas permitam um uso adequado deste resíduo e/ou apresentem limitações. Como o lodo de esgoto possui grande quantidade de matéria orgânica em sua composição, ele pode ser utilizado como fonte de energia ou como matéria-prima na obtenção de novos produtos. O foco deste estudo foi analisar os principais compostos obtidos com a micropirólise rápida do lodo de esgoto anaeróbio proveniente da ETE Mangueira (Recife-PE, Brasil), comparando-os com os produtos pirolíticos reportados na literatura bem como suas possíveis aplicações. Os testes foram feitos em duplicata em um micropirolisador acoplado a um cromatógrafo GC-MS a 450°C, 600°C e 750°C. Compostos como hidrocarbonetos, álcoois, cetonas, aldeídos, ácidos carboxílicos, nitrilas, fenóis, aromáticos nitrogenados e, em menor quantidade, amidas, ésteres, éteres e aminas foram identificados. Estes compostos podem ser destinados para a produção de biocombustíveis, como é o caso dos hidrocarbonetos, álcoois, ácidos carboxílicos, éteres e ésteres; ou podem ser removidos e aplicados na fabricação de novos Palavras-chave:py-GC/MS; lodo de esgoto; aproveitamento de resíduos; biocombustíveis; compostos com valor agregado.
