Abstract

EL OBJETO DE LA INVENCION ES UN PROCESO PARA LA ELABORACION DE ACROLEINA MEDIANTE LA DESHIDRATACION DE GLICERINA EN LA FASE LIQUIDA O EN LA FASE GASEOSA RESPECTIVAMENTE EN CATALIZADORES DE SUSTANCIA SOLIDA ACIDA. EN CONTRA DE LOS CONOCIDOS PROCESOS SE AUMENTA SEGUN LA INVENCION MEDIANTE SELECTIVIDAD MAS ALTA EL RENDIMIENTO ESPACIOTIEMPO Y EL TIEMPO DE PARADA DEL CATALIZADOR. UNA MEZCLA GLICERINAAGUA CON UN CONTENIDO EN GLICERINA DESDE 10 HASTA 40 % EN PESO EN UNA TEMPERATURA DESDE 180 HASTA 340 FASE GASEOSA) SE TRATA EN UN CATALIZADOR DE SUSTANCIA SOLIDA CON UN VALOR HO (FUNCION ACIDA HAMMETT''SCHE) MENOR DE +2, DE FORMA PREFERENTE MENOR DE -3.
