Liquid hydrogenations are often effected in slurry reactors using a finely powdered suspended catalyst. The catalyst is easily washed out with the exit fluid. Present practice is to filter the exit stream and then backwash the filter to recover the catalyst. Increased pressure drop due to pore plugging of the filter seriously limits the use of this method. Research in magnetic filtering is being conducted to address this problem.

液体加氢通常在浆态反应器中使用粉末细小的悬浮催化剂进行。催化剂很容易被出口液体冲走。目前的做法是过滤出口气流，然后反冲洗过滤器以回收催化剂。过滤器堵塞导致的压降增加严重限制了这种方法的使用。为了解决这个问题，正在进行磁过滤方面的研究。
