[en] This project examines the stability of the copper catalyst used in the selective reaction of FUR to FOL in liquid phase using as solvent MF. For this purpose, the effect of the solvent and the product involved in the reaction, MF and FOL, respectively, will be investigated. During the process, the cause of the deactivation of the catalyst was analyzed, identifying carbonaceous deposits that contaminate it. Subsequently, the best method of reactivating the catalyst using different solvents and testing the calcination of the catalyst has been sought. The solvents tested: MF, toluene, THFA and ZME. Using the ZME as a reactivation solvent, this has also been used as the reaction solvent to test its viability in the react ion and reactivation. After the test, the ZME is considered better solvent than the MF and this can be used both in the reaction and in the reactivation.

[eu] Proiektu honetan, fase likidoan furfuraletik (FUR) abiatuta alkohol furfurilikoaren (FOL) formakuntza selektiboan parte hartzen duen kobre katalizatzailearen egonkortasuna aztertzen da 2-metilfurana (MF) disolbatzailea izanik. Horretarako, erreakzioan parte hartzen duten disolbatzailearen eta produktuaren eragina ikertuko da, MF-a eta FOL-a hurrenez hurren. Prozesuan zehar katalizatzailearen desaktibazioaren zergatia aztertuko da, hau kutsatzen duten karbonodun ezarpenak identifikatuz. Ondoren, katalizatzailea berraktibatzeko metodorik hoberena bilatuko da disolbatzaile ezberdinak erabiliz eta katalizatzailearen kaltzinazioa probatuz. Probatutako disolbatzaileak: MF, toluenoa, 2-metiltetrahidrofurana (MTHF) eta ziklopentil metil eterra (ZME) izan dira. ZME-a disolbatzaile moduan erabilitako berraktibazio metodoa erabiliz, erreakzio disolbatzaile moduan erabili da honen bideragarritasuna erreakzioan eta berraktibazioan probatuz. Proben ostean, ZME-a, MF-a baino hobea dela ikusten da eta erreakzio zein berraktibazio disolbatzaile gisa erabil daitekeela. RESUMEN En este proyecto se examina la estabilidad del catalizador de cobre utilizado en la reacción selectiva del FUR a FOL en fase liquida utilizando como disolvente MF. Para este fin, se investigará el efecto del disolvente y del producto implicado en la reacción, MF y FOL, respectivamente. Durante el proceso, se ha analizado la causa de la desactivación del catalizador, identificando deposiciones carbonosas que lo contaminan. Posteriormente, se ha buscado el mejor método de reactivación del catalizador usando diferentes disolventes y probando la calcinación del catalizador. Los disolventes probados: MF, tolueno, THFA y ZME. Usando el ZME como disolvente de reactivación, este se ha utilizado como disolvente de la reacción para probar su viabilidad en la reacción y la reactivación. Después de la prueba, el ZME se considera mejor disolvente que el MF y este, puede usarse tanto en la reacción como en la reactivación.
