Abstract
An ammonia generating apparatus comprises a housing comprising a first end wall on which a reductant injector configured to insert a reductant into the housing is mountable. A heating coil assembly is disposed within the housing. A first end of the heating coil assembly is located proximate to a location of the first end wall where a reductant injector tip of the reductant injector is located when the reductant injector is mounted on the first end wall. The heating coil assembly is configured to generate heat sufficient to thermolyze the reductant to generate ammonia and reaction byproducts, in response to an electric current being passed therethrough. A hydrolysis catalyst can be disposed downstream of the heating coil assembly for catalyzing hydrolysis of the reaction byproducts into ammonia.
