โœฆ Synopsis

A model experiment is carried out to determine the desorption properties of PAH's from carbon, a~d NaCl-particles. In a second step these model particles are replaced by actual combustion particles from a sparkignition-, a diesel-engine and a domestic oilburner. As a sorbate perylene is used. The dieselparticles show a pronounced size dependence of the desorption temperature of perylene. The desorption temperature increases with increasing particle diameter. While pure carbon particles show a behaviour similar to that of particles of a spark-ignition-engine, NaCl-particles seem not to be suitable for simulation of actual combustion particles.

A mathematical model to analyse the internal combustion of a porous carbon particle is presented. The carbon particle is modeled as a porous sphere with uniform spherical pones arranged on a simple cubic lattice extending throughout the particle volume. During combustion, oxygen diffuses into the pa
