The invention discloses a method for catalyst recovery and furfuryl alcohol clarification during furfuryl alcohol production, which comprises the following specific steps that: rough furfuryl alcohol carrying a catalyst is delivered from a rough furfuryl alcohol storage tank to a ceramic membrane separation device through a delivery pump, reflux containing the catalyst is intercepted by the ceramic membrane system through cross-flow filtration and returns to the rough furfuryl alcohol storage tank through a return pipe, and the clear furfuryl alcohol solution penetrates through the ceramic membrane system and flows into the clear furfuryl alcohol solution storage tank. The method of the invention has the advantages of high catalyst removal rate, low energy consumption, short production cycle and the like.
