Abstract

"MéTODO E APARELHO PARA DETERMINAR A ATIVIDADE E COMPORTAMENTO DE ENVELHECIMENTO DE UM CATALISADOR". A invenção refere-se a um método de determinar a atividade e comportamento de envelhecimento de um catalisador. Para esse propósito, duas subcorrentes independentes de gases externos de combustão são produzidas e misturadas antes de entrarem em contato com o catalisador. A primeira subcorrente de gases externos de combustão é preferivelmente produzida por combustão de um combustível de motor e forma a maior parte dos gases externos de combustão. A segunda subcorrente de gases externos de combustão é produzida por meio de um combustor de gás cuja razão de ar pode ser ajustada dentro de uma ampla faixa. A mistura dessa segunda subcorrente de gases externos de combustão na primeira subcorrente permite que a composição da corrente total seja ajustada de uma maneira definida.
