Abstract
La invención se refiere a sistemas y métodos para calentar un material reductor de sólidos o líquidos (902) tal como un material con contenido de urea para la reducción catalítica selectiva ('SCR', por sus siglas en inglés) de NOx utilizando un calor almacenado en un material de almacenamiento de energía térmica (320), tal como un material de cambio de fase. El calor almacenado puede ser calor proveniente de residuos de escape, tal como proveniente de un gas de escape (700) de un motor de combustión interna. El material reductor puede ser un material reductor de sólidos. Otros materiales reductores incluyen soluciones a cosas tales como una solución acuosa que contiene, que consiste esencialmente en, o que consiste en urea y agua. En un aspecto, el proceso puede incluir un paso para evaporar una solución acuosa de urea para la hidrólisis de urea inmediata.
