Abstract
SE DESCRIBE UN PROCESO DE PRODUCCION DE HIDROCARBUROS AROMATICOS A PARTIR DE UNA CARGA DE HIDROCARBUROS ALIFATICOS SATURADOS DE 2 A 12 ATOMOS DE CARBONO EN UN RECINTO 1 QUE COMPRENDE UNA PLURALIDAD DE TUBOS 3 LLENOS DE UN CATALIZADOR, PARALELOS, DISPUESTOS EN HILERAS. SE EFECTUA UNA FASE LLAMADA DE REACCION Y UNA FASE DE REGENERACION DEL CATALIZADOR EN LOS TUBOS DEL RECINTO. EL CALENTAMIENTO DE LOS TUBOS SE REALIZA POR MEDIOS DE CALENTAMIENTO 6 RADIANTES APROPIADOS, SITUADOS ENTRE DOS HILERAS SUCESIVAS, DISPUESTOS EN CAPAS SENSIBLEMENTE PERPENDICULARES A LOS TUBOS. ESTAS CAPAS CALIENTAN UNA PRIMERA PARTE DE LOS TUBOS (DEL LADO DE LA ALIMENTACION) CON UN FLUJO TERMICO SUPERIOR AL FLUJO TERMICO MEDIO DE LOS MEDIOS DE CALENTAMIENTO Y UNA SEGUNDA PARTE SUBSIGUIENTE CON UN FLUJO MEDIO A LO SUMO IGUAL AL FLUJO TERMICO MEDIO, DE TAL MANERA QUE LA ISOTERMICIDAD DEL CATALIZADOR SE MANTIENE SENSIBLEMENTE, GRACIAS A MEDIOS DE CONTROL ADECUADOS. APLICACION EN LA PRODUCCION DE BENCENO, TOLUENO Y XILENOS.
