▎ 摘  要

NOVELTY - Purifying raw material of olefin metathesis reaction comprises contacting raw material for olefin metathesis reaction with metal particle mixture to remove catalyst toxic impurities to obtain a purified raw material for olefin metathesis reaction. The metal particle mixture is a mixture of metal particles containing manganese, iron, cobalt, and/or nickel. USE - The method is useful for purifying raw material of olefin metathesis reaction. The removal agent is useful for removing catalytic toxic impurities in a raw material of olefin metathesis reaction. ADVANTAGE - The method: has high impurities removing rate; is simple and economical; minimizes the amount of metathesis catalyst usage ( less than or equal to 10 ppm) and maximizes the catalyst activity ( greater than or equal to 50000 TON). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) removal agent comprising metal particle mixture in which metal particles containing manganese, iron, cobalt, and/or nickel are mixed; (2) producing removing agent comprising (I) preparing a metal precursor mixture solution by dissolving at least two transition metal precursors in an appropriate solvent, (II) preparing a slurry of the metal precursor mixture and the porous material by adding a porous material to the metal precursor mixture solution, (III) drying the slurry to obtain a porous material containing a metal precursor mixture, (IV) heat-treating the metal precursor mixture-containing porous material to obtain metal particle mixture-containing porous material, and (V) reducing and activating the porous material containing the metal particle mixture obtained by the heat treatment; and (3) olefin metathesis reaction method comprising performing an olefin metathesis reaction in presence of catalyst for olefin metathesis reaction using a raw material for olefin metathesis reaction purified from which catalyst toxic impurities are removed
