Abstract

"PESSULFURIZAçãO DE UM CATALISADOR ACUMULADOR POR AQUECIMENTO". A invenção refere-se a um processo para o aquecimento de um catalisador mestre, integrado ao menos atrás de um pré-catalisador, através do suprimento de combustível de gás de escape não queimado e produzido pelo motor, diante do catalisador mestre, com a simultânea presença de excedente de ar diante do catalisador mestre, no qual a geração pelo motor do combustível não queimado está desacoplado em sentido temporal e/ou espacial da geração pelo motor de excedente do ar no gás de escape."PERSULFURIZATION OF A HEAT ACCUMULATOR CATALYST". The invention relates to a process for heating a master catalyst integrated at least behind a pre-catalyst through the supply of unburned exhaust gas produced by the engine in front of the master catalyst with the simultaneous Excess air in front of the master catalytic converter, in which the engine generation of the unburned fuel is decoupled in a temporal and / or spatial direction from the generation of the exhaust air engine in the exhaust gas.
