Abstract
A NOX abatement system includes a first NOX adsorber capable of being disposed in-line and downstream of and in fluid communication with an engine. The NOX abatement system further includes a selective catalytic reduction catalyst disposed in-line and downstream of, and in direct fluid communication with, the first NOX adsorber. The selective catalytic reduction catalyst is capable of storing ammonia. An off-line reformer is disposed in selective communication with and upstream of the first NOX adsorber and the selective catalytic reduction catalyst. The reformer is capable of producing a reformate that includes primarily hydrogen and carbon monoxide.
