The gas/liquid mass transport is determinant for the investigated reaction of the 3rd phase of SFB/TR 63. The investigation of the mass transport mechanisms is a major challenge due to the occurrence of numerous phase structures and possible transport paths. The goals of project A10 N are the estab-lishment of a fundamental understanding of gas/liquid mass transport for reactive multiphase sys-tems as well as the creation of an accompanying model. To this end the influence of various parame-ters on the kLa value should be measured using a stirred tank reactor and the contribution of kL and a differentiated with help of a falling film contactor.

气/液传质是所研究的 SFB/TR 63 第三相反应的决定因素。由于存在大量相结构和可能的传质路径，因此传质机制的研究是一项重大挑战。 A10 N 项目的目标是建立对反应多相系统的气体/液体传质的基本了解以及创建相应的模型。为此，应使用搅拌釜反应器测量各种参数对 kLa 值的影响，并借助降膜接触器测量 kL 的贡献和微分。
