    • A process wherein a liquid influent stream containing such an amount of a reactant that decomposition thereof to a desired concentration evolves, at the prevailing pressure and temperature, at least 0.5 volumes of gas per volume of the influent stream, is continuously passed through a volume of a particulate catalyst that is sufficient to decompose said reactant to said desired concentration and the evolved gas rises to the surface of said liquid 7a,b,c,d and disengages therefrom into a gas space above said liquid, thereby providing an effluent stream having said desired concentration of said reactant. In order that back mixing of the effluent stream with said influent stream is avoided, the catalyst is disposed in a plurality of serially connected reaction volumes, 4a,b,c,d each of which has a liquid surface from which evolved gas can disengage into the gas space, and the extent of reaction in each of said reaction volumes is limited by providing that the depth of catalyst in each reaction volume is such that the rate at which gas disengages from the liquid surface of each reaction volume is less than 0.05 m³.s⁻¹ per m² of the liquid surface of that reaction volume.
    • 一种方法,其中含有这种量的反应物的液体流入物流,其分解为所需浓度,在现行的压力和温度下,每体积流入物流至少0.5体积的气体,连续地通过一定量的 足以将所述反应物分解成所需浓度的颗粒催化剂,并且放出的气体升至所述液体7a,b,c,d的表面,并从其分离成所述液体上方的气体空间,由此提供具有所述液体 所需反应物的浓度。 为了避免流出物流与所述流入物流的反向混合,催化剂设置在多个串联连接的反应体积4a,b,c,d中,每个反应体积具有液体表面,放出气体可以从该表面脱离成 气体空间和每个所述反应体积中的反应程度受到限制,条件是每个反应体积中的催化剂的深度使得气体与每个反应体积的液体表面脱离的速率小于0.05m <3> .s < - > <1>每m 2的该反应体积的液体表面。
