| Abstract |
This literature search was conducted to bring together and examine the literature pertaining to the fate of sulfur oxides in automotive exhaust systems. The literature was reviewed to investigate the thermodynamic potential and kinetics of forming the trioxide and to examine the fate of both oxides in the exhaust system. Since sulfuric acid emissions may be deleterious, the literature pertaining to removal of sulfur oxides from gaseous streams was reviewed. Stress was placed on the use of metal-oxide sorbents for this purpose. To cover these subjects, the body of this report is divided into four sections. The first section details the thermodynamics of sulfur trioxide formation, reaction with water, and condensation. The second section examines possible reaction with materials in the exhaust gas or system. The third system reviews the catalytic oxidation of sulfur dioxide on platinum catalysts. The last section examines possible means of removing sulfur trioxide from the exhaust stream. |
