LA EMISION Y FORMACION DE PARTICULAS Y AEROSOLES PROCEDENTE DE LA QUEMA DE COMBUSTIBLES ES UNO DE LOS ASPECTOS CLAVE EN LA CONTAMINACION ATMOSFERICA FUNDAMENTALMENTE EN ENTORNOS URBANOS. LOS AEROSOLES AFECTAN A LA VISIBILIDAD, CONTRIBUYEN DE FORMA DECISIVA AL CAMBIO CLIMATICO Y CONSTITUYEN UN RIESGO PARA LA SALUD. LA BUSQUEDA DE NUEVOS COMBUSTIBLES INCIDE TANTO EN ASPECTOS DE EFICIENCIA ENERGETICA COMO EN LOS MEDIAMBIENTALES DERIVADOS DE LAS EMISIONES DE PARTICULAS Y MATERIALES VOLATILES EN FASE GASEOSA. LAS EMISIONES DIRECTAS, PROCEDENTES DEL USO DE COMBUSTIBLES CONVENCIONALES Y COMBUSTIBLES DE NUEVAS GENERACIONES, SE CONOCEN AUNQUE CON DIFERENTES GRADOS DE PRECISION, PERO QUEDA AUN UN RETO IMPORTANTE POR RESOLVER: ¿QUE OCURRE DESPUES CON ESAS EMISIONES? ESTO ES, LA CARACTERIZACION DE LOS PROCESOS REACTIVOS DE LOS COMPUESTOS EMITIDOS UNA VEZ QUE SE ENCUENTRAN EN LA ATMOSFERA DONDE INTERVIENEN FACTORES COMO LA PRESENCIA DE RADIACION SOLAR, NIVELES ALTOS DE NOX, SO2, HUMEDAD RELATIVA VARIABLE, ETC. EL ESTUDIO DE ESTOS PROCESOS ES IMPRESCINDIBLE PARA CONOCER LOS MECANISMOS DE NUCLEACION, CRECIMIENTO, ENVEJECIMIENTO DE LAS PARTICULAS, SUS PROPIEDADES Y PARA PODER EVALUAR LOS EFECTOS MEDIOAMBIENTALES ASI COMO LAS TRANSFORMACIONES DE LAS ESPECIES GASEOSAS. LA ESTRATEGIA ESPAÑOLA DE CIENCIA Y TECNOLOGIA Y DE INNOVACION RECOGE ESTA DOBLE RETO EN SU ACCION 5 ¿ACCION SOBRE EL CAMBIO CLIMATICO Y EFICIENCIA EN LA UTILIZACION DE RECURSOS Y MATERIAS PRIMAS Y EL PROYECTO CRAECOMB, PRETENDE ARROJAR INFORMACION SOBRE ESTOS ASPECTOS, ABORDANDO LOS LOS SIGUIENTES OBJETIVOS: _x000D_ 1. ESTUDIAR EL EFECTO DE LA EXPOSICION DE LOS AEROSOLES PRIMARIOS PROCEDENTES DE LA QUEMA DE COMBUSTIBLES CONVENCIONALES Y BIOCOMBUSTIBLES A LAS CONDICIONES TIPICAS DE UNA ATMOSFERA URBANA CONTAMINADA, EXPOSICION A RADIACION, DIFERENTES NIVELES DE NOX, SO2, RADICALES LIBRES Y COMPUESTOS ORGANICOS VOLATILES Y SEMIVOLATILES. COMO ASPECTOS DE ESPECIAL NOVEDAD SE ESTUDIARAN LOS CAMBIOS DE PROPIEDADES FISICOQUIMICOS EN LA SUPERFICIE, COMPOSICION, POLARIDAD, HIGROSCOPICIDAD, ETC., QUE DEFINEN LOS TIEMPOS DE VIDA ATMOSFERICOS, LA CAPACIDAD DE ABSORCION DE RADIACION Y SU CAPACIDAD DE ACTIVACION COMO NUCLEOS DE CONDENSACION DE NUBES._x000D_ 2. CARACTERIZAR LOS FACTORES CLAVE DE LA FORMACION IN SITU Y POSTERIOR REACTIVIDAD DE NUEVAS PARTICULAS DE AEROSOLES ORGANICOS SECUNDARIOS (SOA) EN ZONAS URBANAS A PARTIR DE COMPUESTOS AROMATICOS, QUE SE ENCUENTRAN PRESENTES EN LA MAYORIA DE LAS EMISIONES DERIVADAS DEL USO DE COMBUSTIBLES. COMO ASPECTO NOVEDOSO, SE PROPONEN EXPERIMENTOS PIONEROS PARA EVALUAR EL PAPEL DE LAS REACCIONES DE OZONO UNA VEZ QUE SE HA PRODUCIDO LA PERDIDA TOTAL O PARCIAL DE LA AROMATICIDAD. HALLAZGOS RECIENTES POSTULAN QUE LAS REACCIONES DE OZONO CON LOS INTERMEDIOS DE REACCION PUEDEN CONDUCIR A LA OXIDACION DE SO2 A ACIDO SULFURICO. ESTOS EXPERIMENTOS PUEDEN PERMITIR LA IDENTIFICACION DE LOS COMPUESTOS QUE PRODUCEN SOA DE MANERA EFICAZ. _x000D_ 3-ESTUDIAR LOS PROCESOS REACTIVOS EN FASE GASEOSA Y EL POTENCIAL DE FORMACION DE SOA DE COMPUESTOS CARACTERISTICOS DE LAS EMISIONES DE BIOCOMBUSTIBLES QUE SE CARACTERIZAN POR LA PRESENCIA DE UN MAYOR NUMERO DE GRUPOS FUNCIONALES CON OXIGENO._x000D_ 4-TRABAJAR EN EL DESARROLLO DE METODOS DE SINTESIS DE NUEVOS BIOCOMBUSTIBLES A PARTIR DE RESIDUOS._x000D_ 5- INTEGRAR TODA LA INFORMACION PARA EVALUAR LAS IMPLICACIONES MEDIOAMBIENTALES DERIVADAS DE LAS EMISIONES PROCEDENTES DE ESTOS NUEVOS COMBUSTIBLES.

THE EMISSION AND FORMATION OF PARTICLES AND AEROSOLS FROM THE BURNING OF FUELS IS ONE OF THE KEY ASPECTS OF ATMOSPHERIC POLLUTION FUNDAMENTALLY IN URBAN ENVIRONMENTS. AEROSOLS AFFECT VISIBILITY, CONTRIBUTE DECISIVELY TO CLIMATIC CHANGE AND POSE A HEALTH RISK. THE SEARCH FOR NEW FUELS AFFECTS BOTH ENERGY EFFICIENCY AND ENVIRONMENTAL ASPECTS DERIVED FROM EMISSIONS OF VOLATILE PARTICLES AND MATERIALS IN THE GAS PHASE. DIRECT EMISSIONS, FROM THE USE OF CONVENTIONAL FUELS AND NEW-GENERATION FUELS, ARE KNOWN BUT WITH VARYING DEGREES OF PRECISION, BUT THERE IS STILL A MAJOR CHALLENGE TO BE ADDRESSED: WHAT HAPPENS AFTER THESE EMISSIONS?
