A New Route of Valorization of Petrochemical Wastewater : Recovery of 1,3,5-Tris (4-tert-butyl-3-hydroxy-2,6-dimethyl benzyl)–1,3,5-triazine-2,4,6-(1H,3H,5H)-trione (Cyanox 1790) and Its Subsequent Application in a PP Matrix to Improve Its Thermal Stability
Hernández-Fernández, Joaquín; Ortega-Toro, Rodrigo; López-Martínez, Juan (Cartagena de IndiasCampus Tecnológico, 2023-02-21)The various chemicals in industrial wastewater can be beneficial for improving its circularity. If extraction methods are used to capture valuable components from the wastewater and then recirculate them throughout the ... -
Active Films Based on Starch and Wheat Gluten (Triticum vulgare) for Shelf-Life Extension of Carrots
Rivera Leiva, Andrés Felipe; Hernández-Fernández, Joaquín; Ortega Toro, Rodrigo (Cartagena de Indias, 2022)The use of biodegradable biopolymers with the incorporation of active ingredients has been considered as an alternative to extend the useful life of food. Therefore, the objective of this research was to develop active ... -
Characterization of Microplastics in Total Atmospheric Deposition Sampling from Areas Surrounding Industrial Complexes in Northwestern Colombia
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Trilleras, Jorge (Cartagena de Indias, 2022)In this study, the total atmospheric deposition of microplastics in places near an industrial complex in Cartagena, Colombia is evaluated by taking samples at three points at different distances from the industrial zone. ... -
Experimental Study of the Impact of Trace Amounts of Acetylene and Methylacetylene on the Synthesis, Mechanical and Thermal Properties of Polypropylene
Hernández-Fernández, Joaquín; Vivas-Reyes, Ricardo; Toloza, Carlos A. T. (Cartagena de Indias, 2022)During the production of polymer-grade propylene, different processes are used to purify this compound and ensure that it is of the highest quality. However, some impurities such as acetylene and methyl acetylene are ... -
Furan as Impurity in Green Ethylene and Its Effects on the Productivity of Random Ethylene–Propylene Copolymer Synthesis and Its Thermal and Mechanical Properties
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Márquez, Edgar (Cartagena de Indias, 2023)The presence of impurities such as H2S, thiols, ketones, and permanent gases in propylene of fossil origin and their use in the polypropylene production process affect the efficiency of the synthesis and the mechanical ... -
Identifying, Quantifying, and Recovering a Sorbitol-Type Petrochemical Additive in Industrial Wastewater and Its Subsequent Application in a Polymeric Matrix as a Nucleating Agent
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; Marquez, Edgar (Cartagena de Indias, 2023)Currently, polypropylene (PP) is highlighted using sorbitol-based clarifying agents since these agents are high quality, low cost, and work as a barrier against moisture, which makes PP ideal for packaging food, beverages, ... -
Iron Oxide Powder as Responsible for the Generation of Industrial Polypropylene Waste and as a Co-Catalyst for the Pyrolysis of Non-Additive Resins
Hernández-Fernández, Joaquín; Castro-Suarez, John R.; Toloza, Carlos A. T. (Cartagena de Indias, 2022)For the synthesis of polymeric resins, it is of great importance to review the raw materials and the equipment to be used to avoid the presence of compounds that may affect the effectiveness of the polymerization and the ... -
Recovery of (Z)-13-Docosenamide from Industrial Wastewater and Its Application in the Production of Virgin Polypropylene to Improve the Coefficient of Friction in Film Type Applications
Hernández-Fernández, Joaquín; Puello-Polo, Esneyder; López-Martínez, Juan (Cartagena de Indias, 2023-01-09)Additives play an important role in the production of plastic materials through their application, in which the mechanical, thermal, and physical properties of polymers are improved, making them last longer and be more ... -
Valoration of the Synthetic Antioxidant Tris-(Diterbutyl-Phenol)-Phosphite (Irgafos P-168) from Industrial Wastewater and Application in Polypropylene Matrices to Minimize Its Thermal Degradation
Hernández-Fernández, Joaquín; Cano, Heidis; Reyes, Ana Fonseca (Cartagena de IndiasCampus Tecnológico, 2023-04-02)Industrial wastewater from petrochemical processes is an essential source of the synthetic phenolic phosphite antioxidant (Irgafos P-168), which negatively affects the environment. For the determination and analysis of ...
