Abstract
SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE ALCOHOLES GRASOS. SE ESTERIFICA UN ACIDO GRASO O UNA MEZCLA DE ACIDOS GRASOS EN UN REACTOR DE COLUMNA EN QUE HAY VARIAS BANDEJAS DE ESTERIFICACION QUE CADA UNA TIENE UNA RETENCION DE LIQUIDO PREDETERMINADA Y QUE CONTIENEN UNA CARGA DE UN CATALIZADOR DE ESTERIFICACION SOBRE ELLAS, EJ. UNA RESINA DE INTERCAMBIO DE IONES QUE CONTIENE GRUPOS DE -SO SUB 3H Y/O -COOH. UNA FASE LIQUIDA QUE CONTIENE EL ACIDO GRASO O LA MEZCLA DE ACIDOS GRASOS FLUYE HACIA ABAJO DEL REACTOR DE COLUMNA DESDE UNA BANDEJA DE ESTERIFICACION A LA SIGUIENTE QUE SE ENCUENTRA ABAJO EN SENTIDO CONTRARIO A UNA CORRIENTE DE VAPOR DE ALCANOL INFERIOR QUE FLUYE HACIA ARRIBA, EJ. VAPOR DE METANOL. UN VAPOR DE ALCANOL INFERIOR RELATIVAMENTE SECO (AGUA QUE NO CONTIENE MAS DE 5 MOLES %) SE INYECTA EN EL FONDO DEL REACTOR DE COLUMNA. EL AGUA DE LA ESTERIFICACION SE EXTRAE DE LA PARTE SUPERIOR DEL REACTOR DE COLUMNA EN LA CORRIENTE DE VAPOR, AL TIEMPO QUE SE RECUPERA UN PRODUCTO DE ESTER DELSUMIDERO DEL REACTOR. A MEDIDA QUE EL LIQUIDO FLUYE HACIA ABAJO DE LAS BANDEJAS SE ENCUENTRA CON UN ALCANOL INFERIOR QUE ES PROGRESIVAMENTE MAS SECO. EL PRODUCTO DE ESTER RECUPERADO DEL FONDO DEL REACTOR TIENE UN CONTENIDO DE ESTER DE POR LO MENOS 99 MOLES % (CALCULADO SOBRE UNA BASE SIN ALCANOL INFERIOR). ESTE PRODUCTO DE ESTER SE SOMETE ENTONCES A UNA HIDROGENACION DE LA FASE DE VAPOR, UTILIZANDO UN CATALIZADOR OXIDO DE OXIDO DE ZINC DE COBRE REDUCIDO NORMAL. LA MEZCLA RESULTANTE CONTIENE, ADEMAS DEL 0,5 MOLES % HASTA 5 MOLES % DE ESTER NO REACCIONADO, ALCOHOLES O UN PRODUCTO DE ALCOHOL GRASO Y ALCANOL INFERIOR, SIN QUE SEA NECESARIO SEPARAR EL ALCANOL INFERIOR DEL ESTER SI EL ALCANOL INFERIOR ES METANOL. ESTE ES DESTILADO PARA PRODUCIR UNA FRACCION DE ALCOHOL GRASO QUE CONTIENE UNA CANTIDAD MENOR DE UN ESTER O ESTERES DE ACIDO GRASO DE ALQUILO INFERIOR (EJ. METILO). LA FRACCION DE ALCOHOL GRASO SE SOMETE ENTONCES A TRANSESTERIFICACION PARA CONVERTIR TODO EL ESTER DE ALQUILO INFERIOR SUSTANCIALMENTE PRESENTE EN UN ESTER O ESTERES DE CERA. SE EVAPORA PARCIALMENTE EL ALCANOL INFERIOR RESULTANTE (EJ. METANOL). A CONTINUACION SE DESTILA LA MEZCLA DE TRANSESTERIFICACION INTERMEDIA PARA EXTRAER ALCOHOLES GRASOS. EL RESIDUO OBTENIDO EN ESTE PASO DE DESTILACION SE MEZCLA CON ALCANOL INFERIOR EN EXCESO Y SE VUELVE A TRANSESTERIFICAR PARA RECONVERTIR EN ESTER O ESTERES DE CERA O ESTERES DE ALQUILO INFERIOR. SE VUELVE A DESTILAR ESTA MEZCLA Y SE PUEDEN RECICLAR LA MEZCLA RECUPERADA DE ALCANOL INFERIOR, LOS ESTERES DE ACIDO GRASO DE METILO Y EL ALCOHOL O ALCOHOLES GRASOS. SI SE UTILIZA UN TITANATO DE ALQUILO COMO CATALIZADOR DE TRANSESTERIFICACION SE PUEDEN EFECTUAR ENTONCES LOS DOS PASOS DE DESTILACION SIN TENER QUE SEPARAR ANTES EL CATALIZADOR Y EL RESIDUO NO VOLATIL DEL SEGUNDO PASO DE DESTILACION Y PUEDE SER RECICLADO AL PRIMER PASO DE TRANSESTERIFICACION.
