Abstract

"PROCESSO PARA REGENERAçãO DE CATALISADOR SóLIDO". A presente invenção refere-se a processo para a regeneração de um catalisador sólido que tenha sido usado para a produção de óxido de propileno, por meio de uma reação de epoxidação de propileno com um peróxido orgânico em um reator recheado com o catalisador sólido, que compreende deixar um líquido escoar pelo catalisador recheado no reator, a uma temperatura não-inferior à temperatura reacional máxima da reação de epoxidação. De acordo com a presente invenção, um catalisador pode ser regenerado com uma eficiência extremamente alta, sem que o catalisador seja regenerado fora do reator.
