Provided is an oxidation reactor capable of oxidizing hydrocarbons with both reaction efficiency and energy efficiency. The oxidation reactor according to the present invention includes a liquid inlet channel, a gas inlet channel, a gas-liquid mixing unit, and a flow reactor. Through the liquid inlet channel, a liquid containing a reaction substrate hydrocarbon is introduced. Through the gas inlet channel, a gas containing oxygen and ozone is introduced. The gas-liquid mixing unit mixes the liquid introduced from the liquid inlet channel with the gas introduced from the gas inlet channel. In the flow reactor, an oxidation catalyst is immobilized or packed. The gas-liquid mixing unit houses, in its channel, a mobile particle which is capable of rotating and/or moving to mix the liquid with the gas to thereby form a gas-liquid slug flow. The gas-liquid slug flow is introduced into the flow reactor.

The disclosure relates to a method of performing ozonolysis or ozone-based oxidation on a liquid or emulsified reagent using a tubular falling film reactor with one or multiple tubes wherein the combined ozone and carrier gas flow is co-current.
