“…Besides being able to be applied as biofuels, they can be used in the production of polymers. 40 Also important for the production of polymers, the bio-oil presented a large phenolic composition, with emphasis on phenol (3.72%), p-cresol (2.32%) and catechol (2.16%), which were also found by Li et al 22 in high proportions (area > 1%). However, these compounds plus ketones and aldehydes characterize bio-oil with a high content of oxygenates, reducing their quality for energy purposes.…”

Agro-industrial wastes are abundant and low-cost sources of energy and chemicals. Biomass account for 14% of the world's energy production. Industrial residues of production of soluble coffee (spent coffee grounds -SCG) have great potential due to its large-scale production and can be transformed by pyrolysis, in liquid, solid and gaseous products with applications from energy to chemicals. This work has the objective of producing bio-oil from the pyrolysis of industrial SCG, characterize it by chromatography and indicate its possible applications. As SGC contains a large amount of glycerides, they were extracted from SGC before the pyrolysis, aiming to obtain a better bio-oil from the residue. The yield in vegetable oil was 5.2% and its analyses showed that 50% are saturated acids (mainly palmitic 27.6%) and other 50% are unsaturated ones (mainly linoleic acid 35.3%). This composition qualifies this oil for biodiesel purposes. The residue (SGC after extraction) was submitted to pyrolysis, yielding 30% in liquid products, being 6% bio-oil. The bio-oil was analyzed by gas chromatography being identified free fatty acids, hydrocarbons, phenols and N-compounds. The heteroatomic compounds limit the use as biofuel but can be interesting for the pharmaceutical, agrochemical and fine chemicals industries.

This research valorized Pachira aquatica Aubl.’s fruit shells (PAS) through its energetic characterization and flash pyrolysis for biofuels or chemicals production. The characterization was performed through proximate and ultimate analysis, bulk density, higher heating value (HHV), hemicellulose, cellulose and lignin content, thermogravimetric analysis and absorption spectra in the infrared region obtained by Fourier-transform infrared spectroscopy technique (FTIR). The analytical flash pyrolysis was performed at 500°C in a Py-5200 HP-R coupled to a gas chromatograph (Py-GC/MS). The PAS biomass presents potential for thermochemical energy conversion processes due to its low moisture and ash content, 76.90% of volatile matter, bulk density of 252.6 kg/m3 and HHV of 16.24 MJ/kg. Flash pyrolysis products are mostly phenols or light organic acids derived from the decomposition of polysaccharides. Results confirmed the potential of PAS to produce bio-phenolics, such as 4-methoxyphenol which is an important active ingredient for skin depigmentation used in drugs and cosmetics, and as phenolic extract that can be used as a precursor to resins, applications that convert this forest waste into bio products for industry into a green circular economy.

“…With the increasing interest to find alternatives to fossil fuels, scientists are exploring a diverse range of replacements, and so, it is not surprising that applications of GC×GC in this field are growing. Recent work has explored the composition of bio-oils obtained from vegetable sources and waste products, such as algae, safflower, coffee waste, − rice husk, sugar cane residues, , and coconut fibers for fuel applications. Caramão and co-workers − , optimized the biomass pyrolysis procedure to obtain bio-oils from the last four sources cited above, using GC×GC to obtain their chemical profiles.…”
