This book was released on 2017 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of tertiary alkyl ethers as gasoline components has been gaining relevance in the last decades because they can enhance the gasoline octane rating at the time that they reduce the environmental impact of combustion processes, being therefore considered as environmentally friendly additives. Methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) are the most produced ethers at industrial scale. More recently, ETBE market is acquiring a predominant role compared to MTBE, due to environmental concerns associated with MTBE usage and because ETBE can be manufactured from bioethanol, what confers a bioether character. Apart from MTBE and ETBE, other ethers as tert-amyl methyl ether (TAME) and tert-amyl ethyl ether (TAEE) are interesting alternatives since they can be manufactured from C5 reactive olefins present in gasoline that present drawbacks as high blending vapor pressure or high potential of tropospheric ozone formation. Similar to ETBE, TAEE can be considered as a bioether since bioethanol can be used as reactant. In this sense, ETBE and TAEE can be envisaged as the most promising alternatives as gasoline additives to fulfill the progressively stricter legislation while being compatible with current engines and therefore, a plausible solution at medium-short term. The optimization and integration of chemical processes is an incentive for industrial plants since several benefits can be obtained as savings in operating and maintenance costs. The simultaneous production of several ethers in the same reaction unit can be a clear example of such technology. A simultaneous etherification unit yielding a mixture of ETBE and TAEE would be one of the most interesting configurations. To the best to our knowledge, such a process has not been yet studied at bench scale. The present PhD thesis is focused on the study of the feasibility of producing ETBE and TAEE as one pot synthesis in the same reaction unit since the industrial interest of such ethers implies a realistic possibility of implementation in the near future. The main topics covered and assessed throughout the present manuscript are: the comparison of different chemical pathways to evaluate the process feasibility, the optimization of experimental conditions that maximize etherification yields, the study of the effect of water presence on the ethanol used as reactant, the characterization of potential byproducts and how to avoid side reactions, the study of the chemical equilibrium and the implicit thermodynamics of involved reactions, the assessment of several catalysts in order to find the best catalyst and the catalytic properties influencing the observed catalytic activity, the study of the intrinsic kinetics of the main reactions involved in order to find a reliable kinetic model, the study of the adsorption equilibrium of involved species in a potential catalytic surface and finally, the study of the catalyst deactivation process caused by the presence of acetonitrile in the feed stream. As for the main results, the optimum chemical pathway for producing ETBE and TAEE has been found. Reactants equilibrium conversions and selectivity have been obtained over a wide range of experimental conditions and etherification yields have been empirically modeled and optimized to obtain the experimental conditions that maximize them. Equilibrium constants and thermodynamic state functions of main reactions involved have been experimentally determined, resulting that main etherification reactions are all of exothermic nature. AmberlsytTM35 has been obtained as the best catalyst among evaluated ones. The relation between acid capacity and volume of swollen polymer have been found as the catalyst properties with more influence on the observed catalytic activity. Reliable kinetic models including activation energies and adsorption parameters have been obtained for the main reactions. An Eley-Rideal mechanism has been deduced as the most probable for the reaction system studied. Adsorption equilibrium constants of species on AmberlsytTM35 have been determined in liquid and gas phase. Adsorption of olefins and ethers are comparable and notably lower than that of alcohols. Also diffusivities of species have been estimated. Finally, the catalyst poisoning is enhanced by the concentration of acetonitrile and temperature and a first order kinetic law has been found to describe better the deactivation process.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Ethyl tert-Butyl Ether (ETBE) production from raffinate-1 and ethanol. The process examined is similar to UOP's Ethermax process for isobutylene etherification. In this process the etherification reaction is conducted in two steps, the first step being a conventional reactor and the second a reactive distillation column. Other established commercial etherification processes with similar configuration, like CBI's CDMTBE, Axens' MTBE Process and Evonik's MTBE Process may as well be represented by the economic analysis presented in this report. This report was developed based essentially on the following reference(s): Keywords: Etherification Reaction, Steam Cracking C4, Raffinate-1, Fuel Additive, Oxygenates

This book was released on 2013 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: La utilització de bioetanol per produir compostos diesel seria una forma d'incrementar la producció de diesel (deficitària a Europa), i tan ho més important, de millorar-ne la qualitat i així reduir les emissions nocives de material particulat, òxids de nitrogen, sofre i compostos volàtils. Un èter derivat del bioetanol que té excel·lents propietats com a combustible diesel és l'etil octil èter. L'objectiu d'aquesta tesis és l'estudi de la producció d'etil octil èter en fase líquida mitjançant catalitzadors heterogenis. Això implica la selecció dels reactius i catalitzadors més adequats des d'un punt de vista de rendiment i selectivitat. A més, l'estudi termodinàmic i cinètic de la reacció en permeten tan el disseny com la optimització del procés. Els assajos catalítics s'han realitzat en un reactor de tanc agitat operant en discontinu i en un reactor tubular operant en continu utilitzant resines àcides de bescanivi iònic com a catalitzadors (P=25 bars, T=130-190oC). Els resultats experimentals han mostrat que el compost etil octil èter es pot formar mitjançant l'etilació de 1-octanol a partir de dos reactius provinents d'origen renovable, l'etanol i el dietil carbonat. La comparació de dos agents etilants, etanol i dietil carbonat, ha revelat que es poden obtenir similars selectivitats i rendiments en temps de reacció elevats mitjançant resines àcides de bescanvi iònic, preferiblement de baix contingut de divinil benzè. Tanmateix, l'ús de dietil carbonat és menys competitiu en temps de reacció curts. A més, la formació de CO2 via dietil carbonat i la més alta disponibilitat d'etanol suggereix que l'ús de l'alcohol és preferit des d'un punts de vista tan industrial com ambiental. L'estudi termodinàmic ha revelat que els valors relativament alts de la constant termodinàmica d'equilibri químic en la formació de l'etil octil èter asseguren alts nivells de conversió en un procés industrial. Finalment, un exhaustiu estudi cinètic ha revelat que la velocitat de formació d'etil octil èter a partir d'etanol i 1-octanol és altament inhibit per l'adsorció de l'aigua en els centres actius de les resines. Finalment, s'ha observat que les velocitats de reacció són optimitzades utilitzant una raó molar 1-octanol / etanol de 1.4, un diàmetre de partícula menor a 0.63 mm d'Amberlyst 70 i una temperatura de reactor de 190oC.
