Description:
The search for "Green" alternative processes for the oxidation of hydrocarbons selectively to partial oxygenates has been the subject of intense chemical research for many years. The USEPA is currently investigating an alternative synthesis pathway for the production of alcohols, aldehydes and ketones from saturated hydrocarbons via an environmentally benign photocatalytic process. This aqueous-phase, room temperature oxidation process employs molecular oxygen, titanium dioxide (TiO2), and UV light to synthesize partial-oxygenates. The falling film reactor may offer improved selectivities to partial-oxygenates and an increase in overall conversion of the parent substrate (hydrocarbon) from results obtained in a batch reactor assembly. Current research to be presented includes the effect of suspended catalyst concentration, falling film thickness, exposure time, and substrate type and concentration.
