Both characteristics can modify the ecosystems where vinasses are discharged. Among the phenolic compounds that have been found in the vinasse, several have commercial potential. In order to recover such compounds from different efluents, adsorption resins have been used, like FPX 66. The objective of this work was to recover phenolic compounds from vinasses, and two adsorption methods were evaluated: continuous process using a column packed with resin, and batch process, using flasks. In batch configuration 77.77% of phenolic compounds were removed from vinasses, but only 54.88% of the initial phenolic compounds in vinasse were recovered; while in the continuous configuration, 92.42% of initial phenolic compounds were removed from vinasses, and 82.85% of the initial phenolic compounds in vinasses were recovered. Considering not only recovery percentages but also the time required for the complete process of recovery of phenolic compounds in both configurations, it is concluded that the continuous process, using a column, has the capacity not only to remove more phenolic compounds from the vinasses, but also presents a greater recovery.","PeriodicalId":326700,"journal":{"name":"Revista de Energía Química y Física","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131170886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We sintetized the binary networks and the ternary ones with different percentage from sílica were obtained, incorporating to the system 10% in weight of sílica, carrying out a curing in situ in mass. The interest of this work lies in the association of an inorganic network (SiO2) to two organic networks PU and PMMA. In order to reduce the phase separation that occurs in the PU, PMMA and SiO2 system, coupling agents of organic/inorganic nature were introduced. Optically transparent plaques were obtained using trimethoxysilyl propyl methacrylate and isocyanatopropyl triethoxy silane. The materials were characterized by Fourier Transformed Infrared Spectroscopy, verifying the presence of representative functional groups in each of the samples. The purpose of incorporating these materials to a single network is the improvement of the mechanical, optical and thermal properties of the organic polymers.","PeriodicalId":326700,"journal":{"name":"Revista de Energía Química y Física","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129098323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microalgae exposed to sunlight are able to adapt by synthesizing a greater amount of pigment to dissipate the incident light energy, controlling the supersaturation of cellular photosystems but reducing the efficiency of the use of light. The photoacclimation is described by the content of chlorophyll mass in relation to the carbon content in the biomass (g Chl / g C). In an outdoor photobioreactor, irradiance depends upon geographical location, time of year and atmospheric conditions. In the present proposal, the generation of biomass is established as a dynamic function of the nutrients, represented as C: N:Chl and the primary assimilation of nutrients as Nitrate (N) and Ammonium (A). The results of this research show an evolution of G: C, N: C, Chl: C and biomass as C (carbon) in different scenarios of parameterization showing consistent results.","PeriodicalId":326700,"journal":{"name":"Revista de Energía Química y Física","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121331805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this proposal from the collector, a theoretical efficiency of 25% was obtained, which represents a third part of energy gain compared to a commercial CPC. This efficiency was obtained according to the materials and dimensions implemented. The system is technically feasible to be used for low temperature processes, with average quality of 60 ºC, which can produce significant energy savings and reducing the amount of CO2 emissions, favoring the environment.","PeriodicalId":326700,"journal":{"name":"Revista de Energía Química y Física","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134067721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
