A triphasic bioreactor for physico-chemically treating a gas is disclosed. The triphasic bioreactor comprises a reaction chamber with a liquid and biocatalysts in suspension in the liquid, for catalyzing a reaction between the gas and the liquid to obtain a treated gas and a solution containing a reaction product. A gas bubbling means is provided in the reaction chamber for bubbling the gas to be treated into the liquid thereby dissolving the gas into the liquid and increasing a pressure inside the reaction chamber. The bioreactor further comprises a liquid inlet in fluid communication with the reaction chamber for receiving the liquid and filling the reaction chamber, a liquid outlet in fluid communication with the reaction chamber for releasing the solution and a gas outlet in fluid communication with the reaction chamber to release the treated gas. The bioreactor further comprises a retention device to retain the biocatalysts in the reaction chamber. The invention also concerns a process using the triphasic bioreactor. The triphasic bioreactor may advantageously be used for removing carbonic dioxide from a CO-containing gas.

A treatment unit is disclosed for treating a fluid in continuous mode. This treatment unit provides the opportunity to carry out simultaneously an enzymatic transformation and a capture of a fluid element. The unit has a reservoir with a fluid inlet for receiving a fluid to be treated and a fluid outlet for releasing a treated fluid. The unit also has removable cassettes provided with a reactive material for treating the fluid and two spaced-apart baffle walls in the reservoir for regulating the flow of the fluid therein. The unit further has a reaction chamber defined between each of the two spaced-apart baffles walls. The reaction chamber has an opening for removably inserting therein the cassette. Yet, the unit further has mounting means for mounting the cassette in a reaction chamber spaced-apart from the two baffle walls, whereby a cassette is disposed between two spaced-apart baffle walls and causes the fluid to flow in a zigzag pattern thus further regulating the flow of the fluid.
