In order to purify and recycle alcohol-containing tetrahydrofuran recovered during the preparation of the catalyst for polyolefins, the alcohol-removing adsorption-batch distillation process path is explored.The operability of the process path is verified through lab experiment and the renovation of industrial unit.The obtained tetrahydrofuran has a purity of 99.99%, without containing any alcohols and achieving the purpose of recycling tetrahydrofuran, which ensures the stability of catalyst product quality and reduces the cost effectively.
