HOY EN DIA, LA MAYOR PARTE DEL HIDROGENO SE OBTIENE MEDIANTE PROCESOS DE CONVERSION DE COMBUSTIBLES SOLIDOS, LIQUIDOS Y GASEOSOS. ESTE TIPO DE PROCESOS REQUIERE ELEVADAS TEMPERATURAS DE TRABAJO Y ETAPAS ADICIONALES DE PURIFICACION DEL HIDROGENO PRODUCIDO QUE ENCARECEN SENSIBLEMENTE EL PRECIO FINAL DEL MISMO. ENTRE LOS DISTINTOS PROCESOS PROPUESTOS RECIENTEMENTE PARA LA PRODUCCION DE ESTE IMPORTANTE VECTOR ENERGETICO, CABEN DESTACAR LOS DE REFORMADO ELECTROQUIMICO DE ALCOHOLES, CON LOS QUE SE LOGRA LA PRODUCCION DIRECTA DE H2 DE ELEVADA PUREZA. COMPARADO CON LOS PROCESOS CATALITICOS CONVENCIONALES, ESTE PROCESO TIENE LA VENTAJA DE QUE PERMITE PRODUCIR Y SEPARAR EL H2 EN LA MISMA ETAPA DE REACCION, Y REQUIERE CONDICIONES MUCHO MAS SUAVES DE OPERACION (80-90ºC, 1 ATM). EL HIDROGENO PRODUCIDO PUEDE SER CONVERTIDO DE NUEVO EN ENERGIA LO QUE PUEDE SERVIR DE COMPLEMENTO, SEGUN DEMANDA, DE SISTEMAS RENOVABLES DE PRODUCCION DE ENERGIA NO ESTACIONARIOS. ESTE TIPO DE PROCESOS CONSISTEN EN LA UTILIZACION DE UN REACTOR ELECTROQUIMICO DE MEMBRANA POLIMERICA (PEM) DONDE LA ALIMENTACION ESTA FORMADA POR MEZCLAS ALCOHOL-AGUA. EN EL ANODO DE LA CELDA PEM SE LLEVARIA A CABO LA ELECTRO-OXIDACION DEL ALCOHOL Y LA FORMACION DE PROTONES QUE SERIAN TRANSPORTADOS A TRAVES DE LA MEMBRANA POLIMERICA HASTA EL CATODO DONDE SE RECOMBINARIAN PARA FORMAR HIDROGENO. _x000D_ EN ESTE PROYECTO SE PRETENDEN INVESTIGAR ASPECTOS DE INTERES CIENTIFICO-TECNOLOGICO DE LOS PROCESOS DE REFORMADO ELECTROQUIMICO DE ALCOHOLES COMO MODO DE PRODUCIR HIDROGENO Y UTILIZARLO EN PROCESOS DE HIDROGENACION CON FORMACION DE PRODUCTOS DE MAYOR VALOR AÑADIDO. SE FORMULARIAN DISTINTOS CATALIZADORES ANODICOS CAPACES DE TRATAR CORRIENTES ALCOHOLICAS REALES, COMO LAS QUE PRODUCE Y SUMINISTRARA LA EMPRESA ABENGOA, SOPORTADOS SOBRE NANOESTRUCTURAS DE CARBON, FUNCIONALIZADAS O NO, SUMINISTRADAS POR LA EMPRESA GRAPHENANO Y PEROVSKITAS METALICAS SINTETIZADAS EN EL LABORATORIO DEL GRUPO DE INVESTIGACION. COMO CATODO DEL REACTOR PEM, SE CONSIDERARAN CATALIZADORES QUE FACILITEN LA RECOMBINACION DE LOS PROTONES TRANSFERIDOS Y CATALIZADORES DE HIDROGENACION CON LOS QUE LOGRAR QUE ESTOS PROTONES PUEDAN HIDROGENAR MOLECULAS PARA DAR ORIGEN A OTRAS DE MAYOR VALOR AÑADIDO O CON LAS QUE ALMACENAR QUIMICAMENTE LA ENERGIA ELECTRICA. EL NUEVO CONCEPTO PERMITIRIA UTILIZAR LOS SISTEMAS PEM COMO REACTOR CATALITICO AL PODER UTILIZAR EL HIDROGENO PRODUCIDO IN-SITU POR REFORMADO ELECTROQUIMICO EN PROCESOS DE HIDROGENACION EN CONDICIONES SUAVES DE OPERACION. ADEMAS, EL DESARROLLO ACTUAL DE LOS SISTEMAS PEM EN FORMA DE STACK HACE VIABLE UN SENCILLO ESCALADO DEL PROCESO PROPUESTO. SIMULTANEAMENTE, SE SIMULARA MEDIANTE LA HERRAMIENTA HYSYS (DE ASPENTECH) Y SE EVALUARA ENERGETICA Y EXERGETICAMENTE EL PROCESO DE REFORMADO ELECTROQUIMICO DE ALCOHOLES LO QUE PERMITIRA EL DISEÑO DEL MISMO A ESCALA INDUSTRIAL, SU OPTIMIZACION Y ESTABLECER UNA COMPARATIVA CON LOS PROCESOS CLASICOS DE REFORMADO DE ALCOHOLES. LA PARTICIPACION DE LAS EMPRESAS QUE APOYAN ESTA PROPUESTA SE HACE INDISPENSABLE PARA ESTABLECER LA VIABILIDAD TECNOLOGICA DEL PROCESO QUE SE PROPONE, TANTO DESDE EL PUNTO DE VISTA DE VOLUMEN DE ALCOHOLES A TRATAR, COMO DE LAS POSIBILIDADES DE PRODUCIR CANTIDADES DE NANOESTRUCTURAS DE CARBONO SUFICIENTES PARA CONFORMAR REACTORES INDUSTRIALES. ADEMAS, SE CUENTA CON LA PARTICIPACION DE INVESTIGADORES DEL IRCELYON FRANCES. (Spanish)

TODAY, MOST OF THE HYDROGEN IS OBTAINED THROUGH CONVERSION PROCESSES OF SOLID, LIQUID AND GASEOUS FUELS. THIS TYPE OF PROCESS REQUIRES HIGH WORKING TEMPERATURES AND ADDITIONAL STAGES OF PURIFICATION OF THE PRODUCED HYDROGEN THAT SIGNIFICANTLY INCREASE THE FINAL PRICE OF IT. AMONG THE VARIOUS PROCESSES RECENTLY PROPOSED FOR THE PRODUCTION OF THIS IMPORTANT ENERGETIC VECTOR, WE SHOULD HIGHLIGHT THOSE OF ELECTROCHEMICAL REFORMING OF ALCOHOLS, WITH WHICH THE DIRECT PRODUCTION OF H2 OF HIGH PURITY IS ACHIEVED. COMPARED TO CONVENTIONAL CATALITIC PROCESSES, THIS PROCESS HAS THE ADVANTAGE OF PRODUCING AND SEPARATING H2 AT THE SAME REACTION STAGE, AND REQUIRES MUCH SMOOTHER OPERATING CONDITIONS (80-90 °C, 1 ATM). THE HYDROGEN PRODUCED CAN BE CONVERTED BACK INTO ENERGY WHICH CAN SERVE AS A COMPLEMENT, ACCORDING TO DEMAND, OF NON-STATIONARY RENEWABLE ENERGY PRODUCTION SYSTEMS. THIS TYPE OF PROCESS CONSISTS OF THE USE OF AN ELECTROCHEMICAL POLYMERICA MEMBRANE REACTOR (PEM) WHERE THE FEEDING IS FORMED BY ALCOHOL-WATER MIXTURES. THE ELECTRO-OXIDATION OF ALCOHOL AND THE FORMATION OF PROTONS THAT WOULD BE TRANSPORTED THROUGH THE POLYMERICA MEMBRANE TO THE CATHODE WHERE THEY ARE RECOMBINED TO FORM HYDROGEN WOULD BE CARRIED OUT IN THE PEM CELL ANODE. _x000D_ in this project are treated to look for aspectos of scientific-technological interests of alcoholes electrochemical refurbishment processes as a way to produce HYDROGEN and use it in processes of HYDROGENING WITH MAYOR VALUE PRODUCTS. DIFFERENT ANODIC CATALYSTS CAPABLE OF TREATING ACTUAL ALCOHOLIC CURRENTS, SUCH AS THOSE PRODUCED AND SUPPLIED BY ABENGOA, SUPPORTED ON CARBON NANOSTRUCTURES, WHETHER FUNCTIONALISED OR NOT, SUPPLIED BY GRAPHENANO AND METAL PEROVSKITAS SYNTHESISED IN THE LABORATORY OF THE RESEARCH GROUP, ARE FORMULARIAN. AS A CASE OF THE PEM REACTOR, CATALYSTS WILL BE CONSIDERED TO FACILITATE THE RECOMMENDATION OF THE TRANSFERRED PROTONS AND HYDROGENATION CATALYSTS WITH WHICH TO ACHIEVE THAT THESE PROTONS CAN HYDROGENATE MOLECULES TO GIVE ORIGIN TO OTHERS OF HIGHER ADDED VALUE OR WITH WHICH TO STORE CHEMICALLY THE ELECTRICAL ENERGY. THE NEW CONCEPT WOULD ALLOW THE USE OF PEM SYSTEMS AS A CATALITIC REACTOR BY USING THE HYDROGEN PRODUCED IN-SITU BY ELECTROCHEMICAL REFORMING IN HYDROGENATION PROCESSES IN SMOOTH OPERATING CONDITIONS. MOREOVER, THE CURRENT DEVELOPMENT OF STACK-SHAPED PEM SYSTEMS MAKES A SIMPLE SCALING OF THE PROPOSED PROCESS FEASIBLE. SIMULTANEOUSLY, THE HYSYS (ASPENTECH) TOOL WILL BE SIMULATED AND THE PROCESS OF ELECTROCHEMICAL ALCOHOL REFORMING WILL BE EVALUATED ENERGETICALLY AND EXERGETICATLY, ALLOWING THE DESIGN OF THE ALCOHOLS ON AN INDUSTRIAL SCALE, ITS OPTIMISATION AND A COMPARISON WITH THE CLASSIC PROCESSES OF ALCOHOL REFORMING. THE PARTICIPATION OF THE COMPANIES SUPPORTING THIS PROPOSAL IS INDISPENSABLE IN ORDER TO ESTABLISH THE TECHNOLOGICAL VIABILITY OF THE PROPOSED PROCESS, BOTH FROM THE POINT OF VIEW OF VOLUME OF ALCOHOLS TO BE TREATED, AND THE POSSIBILITIES OF PRODUCING SUFFICIENT QUANTITIES OF CARBON NANOSTRUCTURES TO FORM INDUSTRIAL REACTORS. IN ADDITION, THERE IS THE PARTICIPATION OF RESEARCHERS FROM IRCELYON FRANCES. (English)
