| Research Abstract |
CO2 could be transformed to methanol and ethanol using high efficiency Fenton reaction in which radical generation could be promoted by the repetitive supply of ferrous sulfate, hydrogen peroxide and pH regulator to CO2 saturated sulfate solution. Formic acid, acetic acid, oxalic acid, formaldehyde, acetaldehyde were also formed as intermediate products. Alcohol yield was increased by usage of several catalysts and optimization of process conditions. Furthermore, component of resulting sludge by Fenton reaction was combination of ferrihydrite and schwertmannite, and alcohol yield was increased by control of process conditions such that the ratio of ferrihydrite was maximum in the sludge.
