| 摘要 |
<p>The present invention relates to a column reactor, suitable for the continuous production of a gaseous reaction product by contacting a liquid reaction medium with a gasforming agent fixed to a solid substrate, having an outer shell wall, inlet means for feeding liquid reaction medium into the reactor, outlet means for recovering gaseous reaction product, outlet means for recovering treated liquid reaction medium and at least two reaction zones following one after the other, said reactor being characterized in that each reaction zone comprises a first free volume, a reaction plug, and a second free volume, disposed within said outer shell wall, wherein said first free volume is spaced apart from said second free volume by said reaction plug, wherein said reaction plug, consisting of a suitable solid substrate, is provided with a plurality of gas-forming channels, the walls of said channels having a gas-forming agent fixed thereto, said plug having a periphery adjacent to the outer shell wall, wherein said reaction zone is adapted so that fluid communication between said first free volume and said second free volume is provided by said channels and a circulator by-pass means adapted to allow liquid reaction medium to by-pass said channels, wherein said channels and said by-pass means are adapted to cooperate to facilitate the circulation of an internal current of liquid reaction medium, between said free volumes through said circulatory by-pass means and channels as defined above, and wherein the second free volume of a reaction zone is in fluid communication with the first free volume of the following reaction zone.</p> |
