Removal of hydrocarbons, carbon monoxide and nitric oxides in automotive exhaust with three way catalytic converter
Gerçeker, Duygu; Önal, Işık; Department of Chemical Engineering (2013)
In this study, Three Way Catalysts (TWC) are investigated by using Density Functional Theory (DFT) methods and catalytic activity tests in the dynamic test system. Pd4 or Rh4 cluster adsorbed on ceria (CeO2) and ceria-zirconia (CZO) surfaces together with atomic palladium and rhodium substituted CeO2 and CZO surfaces are investigated for their catalytic activity towards carbon monoxide oxidation and nitric oxide reduction. Relative energy profiles for reaction mechanisms are obtained and activation barriers...
Removal of hydrogen sulfide by regenerable metal oxide sorbents
Karayılan, Dilek; Doğu, Timur; Department of Chemical Engineering (2004)
High-temperature desulfurization of coal-derived fuel gases is an essential process in advanced power generation technologies. It may be accomplished by using metal oxide sorbents. Among the sorbents investigated CuO sorbent has received considerable attention. However, CuO in uncombined form is readily reduced to copper by the H2 and CO contained in fuel gases which lowers the desulfurization efficiency. To improve the performance of CuO-based sorbents, they have been combined with other metal oxides, form...

Pickling process is recognized as one of the strongest acid consuming processes in the steel industry. A pickling solution that contains hydrochloric acid (HCl) is used for the metal surface treatment of steel plants. The same acid can be used for a long period of time by means of a regeneration process, in which iron concentration of the acid is decreased to insignificant concentrations. However, regenerated pickling solutions contain copper, especially when scrap is used to produce steel. Furthermore, cop...
