Method and converter for catalytic conversion of fuel

摘要

Process for catalytically converting fuel to remove nitrogen oxides from I.C. engine exhaust gases comprises feeding the fuel and a partial stream of the exhaust gas separately into a converter; and vaporizing the fuel. An Independent claim is also included for a converter for catalytically converting fuel comprising a vaporization chamber connected to a conversion chamber. The vaporization chamber has feeds for exhaust gas or feed gas and fuel. The conversion chamber contains a catalyst for catalytically converting the fuel. The chambers are connected together so that heat can be transported from the conversion chamber to the vaporization chamber. Preferred Features: The fuel is dehyrogenated or partially oxidized to carboxylic acids and/or carboxylic acid anhydrides. The catalyst is gamma -Al2O3.
