WebRecently many oxidation reactions have been carried out using these catalysts in severe reaction conditions, giving rise to thermal and/or mechanical stresses. Examples of these reactions are: 1) The catalytic total oxidation (CTO) reaction, carried out at reaction temperatures below 1300 °C to reduce the NO x formation and emission [ 5 ]. (1) 2) Many selective oxidation catalysts have been developed for producing fine chemicals of pharmaceutical or academic interest. Nobel Prize–winning examples are the Sharpless epoxidation and the Sharpless dihydroxylation. dr rizik musc

WebOxidation catalyst systems frequently require that extra air, called secondary air, be introduced into the exhaust system in front of the catalyst. Figure 8. Conversion of CO and Hydrocarbons in Oxidation Catalyst. … WebDec 3, 2024 · Examples of homogeneous catalytic reactions The reaction between persulphate ions and iodide ions Persulphate ions are very strong oxidizing agents while iodide ions are very easily oxidized to form iodine. In water, these reactions are very slow. The reaction equation is given below S 2 O 82- + 2I – converts to 2SO 42- + I 2 WebApr 11, 2016 · For example, methane oxidation was found to be promoted by H 2 S on YSZ, which was studied as a sulfur-tolerant catalyst to be used in solid oxide fuel cell applications . Also sour water gas shift, i.e. WGS in the presence of H 2 S tolerant catalyst, has been investigated recently with regards to converting H 2 S-containing streams in ... dr rizis
