The invention discloses a furfuryl alcohol reaction solution catalyst separation technology and belongs to the technical field of furfuryl alcohol production. The furfuryl alcohol reaction solution catalyst separation technology is characterized in that 1, a Cu-Si catalyst is used in furfuryl alcohol production, the Cu-Si catalyst is CuO carried by SiO2, and according to positive charge characteristic of a metal oxide, a flocculating agent is added into a cooled reaction liquid with the catalyst and through adsorption bridging and net capturing effects, the catalyst in the material liquid and the sticking oil analogue subjected to furfuryl alcohol resinification are twined and coated to form large particles so that the problem that fine particles are separated difficultly by sedimentation is solved, 2, a cyclone hydraulic separator is used for separation and the thickened material on the bottom of the separator is subjected to press filtration so that an investment and a use load of a filter press are reduced
