“…The chemical composition of the liquid fractions was determined by gas chromatography using a method previously developed by our research group [39][40][41]. The analysis was carried out by means of an Agilent 7890 A gas chromatograph coupled with a 5977 A single quadrupole mass spectrometer (GC/qMS) (Agilent Technologies, Santa Clara, California, CA, USA) provided with a column Phenomenex ZB-624 (30 m; 0.25 mm i.d.…”

In this work, chemical recycling as an alternative to conventional end-of-life treatments was studied. Two different types of end-of-life tires (ELT), truck tires and mix tires (50:50 mixture of passenger car and truck tires), were pyrolyzed in a batch microwave reactor. The influence of specific power (10, 20, and 30 W/g) on mass distribution was analyzed. The maximum liquid yield was attained at 10 W/g, while the maximum gas yield is obtained at 30 W/g. Liquid fractions were characterized by gas chromatography/quadrupole mass spectrometry (GC/qMS) to identify the main components, and major compounds were quantified. In all samples, limonene (3.76 ± 0.31–6.80 ± 2.37 wt. %) and BTEX (3.83 ± 0.20–1.19 ± 2.80 wt. %) were the main components. Major limonene concentration is obtained in oil produced from truck ELT while higher yields of aromatic compounds are obtained from mix ELT. The maximum BTEX concentration is obtained at 10 W/g being toluene the main compound with a concentration of 2.07 ± 0.42 and 4.63 ± 1.29 for truck and mix ELT, respectively. The separation and purification of these compounds will confer important value to these fractions. Higher yields of the solid fraction are produced when mix tires are pyrolyzed due to the higher concentration of ash in this type of ELT. Recovered carbon black was characterized by measuring the surface area.

“…Para realizar este tipo de tratamiento sobre los residuos plásticos es importante conocer el monómero de partida, entender su estructura, comportamiento frente al calor y biodegradabilidad (Kasar et al, 2020). Este proceso cuenta con cuatro metodologías de valorización, las cuales son la pirólisis (Conesa & Martin, 2009), la hidrogenación (Baena et al, 2020), la gasificación (Lazzarotto et al, 2020) y la metanólisis (Samak et al, 2020), de todas ellas, la más utilizada en la actualidad debido al potencial para obtener compuestos con valor energético es la pirólisis (Jha & Kannan, 2020;Chen et al, 2021).…”

El consumo desmedido y la demanda energética a nivel mundial han generado la necesidad de incorporar los desechos plásticos y de origen agroindustrial a procesos de valorización, para obtener productos energéticos alternativos a partir de tratamientos termoquímicos como la pirólisis rápida, en la cual se generan productos sólidos, líquidos y gaseosos. Desarrollar metodologías que permitan realizar un reciclaje y/o aprovechamiento de residuos generados de diversas industrias, en específico, la polimérica y la agroindustrial, es de suma importancia, dada la contaminación crónica y el impacto ambiental en ecosistemas naturales, cuerpos hídricos y fauna. El objetivo de este artículo es analizar los impactos ambientales de la alta generación de residuos plásticos y agroindustriales, así como determinar la relación entre las condiciones de operación y el rendimiento y selectividad de los productos generados con las características fisicoquímicas de los catalizadores empleados en la pirólisis rápida en pro de la valorización de dichos residuos. Lo anterior se realizó mediante una revisión de la literatura en bases de datos reconocidas para obtener artículos de investigación actualizados y con validez científica. Se encontró que la pirólisis catalizada presenta una mejora respecto al rendimiento y distribución de los productos según la fase activa seleccionada en la que la naturaleza de los metales usados conduce a diversas rutas químicas y por ende, a productos ricos en hidrocarburos.
