1. A method for preparing a Zn—Al slurry catalyst, comprising:
mixing an aluminum sol, a polyhydric alcohol, and a zinc source solution to obtain a sol-gel precursor; and
performing successively an aging treatment and a heat treatment on the sol-gel precursor to obtain the Zn—Al slurry catalysts,
wherein the aging treatment is conducted at 10-30° C. for 3-10 days,
wherein the heat treatment is conducted at 280-300° C. for 6-10 h,
wherein a heating rate to reach a temperature for the heat treatment is 2-5° C./min,
wherein the heat treatment is performed in an inert medium, and
wherein the inert medium is liquid paraffin.
