Experimental testing of catalysts for hybrid combustion

Abstract [en]

A hybrid heating system for the vehicle industry was customized at the Chemical Engineering and Technology unit, KTH School of Chemical Science and Engineering. This work was performed by Pablo Gutiérrez Varona as his final project work and was carried out in co-operation between KTH-Royal Institute of Technology, Universitat de Barcelona, and ReformTech Heating Technologies Sweden AB.

The aim of the thesis was to evaluate the performance of three different catalysts (an uncoated cordierite, a lanthanum manganese hexaaluminate, and palladium over alumina) for a 5 kW adiabatic power hybrid heater developed by ReformTech Heating Technologies Sweden AB. Three different catalysts were tested for the combustion of diesel. The catalysts performances were observed for a wide working range of air-to-fuel ratios in order to find an optimum operation point. The catalysts were evaluated based on the emissions and temperatures profiles.

The most promising results for this application was the Pd-Al2O3 catalyst, 2 CO ppm and 37 NOx ppm for a lambda of 2,3.
