Maya López, Juan CarlosQuinchía Figueroa, Adriana MaríaSánchez Posada, Mario Alejandro2023-08-15T14:12:34Z2025-11-302023-08-15T14:12:34Z2023https://repository.eia.edu.co/handle/11190/6056159 páginasABSTRACT: agricultural production generates significant amounts of residues that are not valued and contributes to environmental pollution; In Colombia alone, 78 million tons of agricultural residues are generated each year. Moreover, only a small fraction of the produced biomass in the agricultural sector correspond to useful products: the “fique” industry uses only the 2% of the produced biomass, the beer industry uses only 8% of the grain nutrients, while palm oil industry uses less than 9% of the produced biomass, in coffee industry only 9,5% of the fruit weight is utilized, while in the paper industry just the 30% of the raw biomass is made of (Cury et al., 2017). The valorization of these residues not only to reduces environmental pollution but also contributes to increase sector productivity through the production of high value products. One of the alternatives for biomass residues characterization is the production of bio-oil through fast pyrolysis with its subsequent upgrade to obtain high value products such as fuels, or chemicals as furfural, acetol (hydroxy acetone), levoglucosan, acetic acid, 5-HMF, hydroxyl-acetaldehyde, products that are used are raw materials in the food, textile, paints, pharmaceutical and cosmetic sectors. The bio-oil from biomass fast pyrolysis is a mixture of compounds coming from the decomposition of the cellulose, hemicellulose and lignin. Particularly, in the bio-oil can be found heavy components such as lignin oligomers, anhydrosugars, and some minerals. The concentration of these heavy components in bio-oil affects subsequent processes as the hydrotreatment to obtain fuels (Iisa et al., 2019). A fraction of the aforementioned heavy components in bio-oil comes from aerosols that are ejected from the biomass particle during fast pyrolysis (primary aerosols), however, the contribution of the aerosols to this heavy fraction is still uncertain, since these aerosols suffer secondary extra-particle reactions within the reactor and there is also formation of secondary aerosols during the condensation process of volatiles products (Montoya et al., 2016). Even though there are multiples studies on the effect of some process parameters and particles characteristics (heating rate, holding temperature, pressure, particle size) on the heavy fraction yield, the effect of these parameters on aerosol production has been little studied. Currently, there is no fast pyrolysis model that considers realistic characteristics of the particle such as shape and anisotropy and provides information about the production of aerosols and its size distribution (Brennan Pecha et al., 2019). The information about the produced aerosols is important for the later analysis of the extra-particle reactions within the reactor and to clarify the participation of primary aerosols on the heavy fraction yield. Based on the problem description presented above the research question for the present work is the following: ¿Is the effect of particle shape and anisotropy on the production primary aerosols significant during biomass fast pyrolysis? This project aims at advancing the current state of knowledge and modelling of biomass fast pyrolysis. The objective of the work is to evaluate aerosol production and the effect of particle characteristics and process parameters during biomass fast pyrolysis.DoctoradoDoctor en Ingenieríaapplication/pdfengUniversidad EIADoctorado en IngenieríaEscuela de Ingeniería y Ciencias BásicasEnvigado (Antioquia, Colombia)Derechos Reservados - Universidad EIA, 2023info:eu-repo/semantics/closedAccesshttp://purl.org/coar/access_right/c_14cbModelling the fast pyrolysis of anisotropic biomass particles with aerosol productionTrabajo de grado - Doctoradohttp://purl.org/coar/resource_type/c_db06info:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/publishedVersionTexthttp://purl.org/redcol/resource_type/TDhttp://purl.org/coar/version/c_970fb48d4fbd8a85Fast pyrolysisBiomassParticle modelAnisotropyBio-oilLICENSElicense.txtlicense.txttext/plain; charset=utf-82515https://repository.eia.edu.co/bitstreams/f4b66815-a588-4f25-9858-b2823501e523/downloadda9276a8e06ed571bb7fc7c7186cd8feMD5711190/6056oai:repository.eia.edu.co:11190/60562023-08-15 09:13:36.234metadata.onlyhttps://repository.eia.edu.coRepositorio Institucional Universidad EIAbdigital@metabiblioteca.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 |
