    dc.descriptionEn la presente investigación se estudió la pirólisis de residuos plásticos de polipropileno (PP) y poliestireno (PS) en presencia de catalizadores zeolíticos HZSM-5 sintetizados con relaciones molares Si/Al de 63, 60 y 57, y a concentraciones del 2, 5 y 10% en masa con respecto al polímero, utilizando un horno abierto con temperatura máxima de 500°C. El seguimiento de la pirolisis se realizó por espectroscopía infrarroja utilizando la técnica de muestreo reflexión total atenuada (FTIR-ATR), a partir de los cuales se escogió la mejor relación molar de zeolita y mejor porcentaje de catalizador. Los datos se cruzaron con los reportes termogravimetricos en una termobalanza en atmósfera de Nitrógeno a una velocidad de calentamiento de 10°C/min. Los estudios de caracterización de las zeolitas sintetizadas permitieron establecer que la fase que compone los materiales es del tipo HZSM-5 con estructura amorfa según Difracción de rayos-X de muestras policristalinas y un área superficial superior a 600m2 /g, con curvas de desorción y absorción de nitrógeno tipo IV, lo cual convierte al material en un buen catalizador. El proceso de la catálisis permitió establecer que la zeolita con la relación molar Si/Al de 63, en un porcentaje del 5% en masa para el polipropileno promueve la descomposición del polímero 101°C por debajo de lo que se presenta sin la presencia del catalizador, y para el poliestireno relación molar Si/Al de 60, en porcentaje del 2% en masa, sin reducción de temperatura, la ruta de descomposición promovida por el catalizador, se fundamenta por la despolimerización y respectiva presencia de carbonilos en las cadenas monoméricas.es_CO
    dc.description.abstractIn the present investigation, the pyrolysis of polypropylene (PP) and polystyrene (PS) plastic waste was studied in the presence of HZSM-5 zeolitic catalysts synthesized with Si / Al molar ratios of 63, 60 and 57, and at concentrations of 2, 5 and 10% by mass with respect to the polymer, using an open oven with a maximum temperature of 500 ° C. The monitoring of the pyrolysis was performed by infrared spectroscopy using the attenuated total reflection sampling technique (FTIR-ATR), from which the best molar ratio of zeolite and best percentage of catalyst was chosen. The data was crossed with the thermogravimetric reports in a thermobalance in Nitrogen atmosphere at a heating rate of 10 ° C / min. The characterization studies of the synthesized zeolites allowed to establish that the phase that composes the materials is of type HZSM-5 with amorphous structure according to X-ray diffraction of polycrystalline samples and a surface area greater than 600m2 / g, with desorption curves and absorption of type IV nitrogen, which makes the material a good catalyst. The catalysis process allowed to establish that the zeolite with the Si / Al molar ratio of 63, in a percentage of 5% by mass for the polypropylene promotes the decomposition of the polymer 101 ° C below what occurs without the presence of the catalyst, and for the polystyrene Si / Al molar ratio of 60, in percentage of 2% by mass, without reduction of temperature, the decomposition path promoted by the catalyst, is based on the depolymerization and the respective presence of carbonyls in the monomeric chains.es_CO
