气液分散与反应问题在磁力反应釜的应用中是经常遇到的，例如硝基芳烃、脂肪腈、烯烃和炔烃的液相催化加氢反应釜、烷基化反应、羰基化反应、氧化反应等。其共同特点是反应速率受气/液传质的控制，而气/液传质涉及到气体分散、气体循环、以及固体催化剂悬浮等过程，问题变得比较复杂。为提高反应速率，工业上一般采用气体外循环、液体外循环和气体内循环三种方式。在磁力反应釜，加氢反应釜，磁力驱动反应釜得到充分的应用。

The gas-liquid dispersion and reaction problems in the application of magnetic reactor is often encountered, for example, nitro aromatic aliphatic nitriles, alkenes and alkynes liquid phase catalytic hydrogenation reactor, alkylation, carbonylation, oxidation etc.. The common characteristic is the reaction rate of air / liquid mass transfer control, and gas / liquid mass transfer involves gas dispersion, gas circulation, and solid catalyst suspension process becomes a complex problem. In order to improve the reaction rate, three methods, gas outer circulation, liquid outer circulation and gas inner circulation, are generally adopted. In magnetic reaction reactor, hydrogenation reactor, magnetic drive reactor has been fully applied.
