The present specification relates to a method comprising: (A) mixing a ferrite-based catalyst molded article with diluent material particles; and (B) adding the mixture to a catalyst reactor, and a method for preparing butadiene using the same.

Catalyst loading method and method for preparation of butadiene by using same

A hydroformylation method including preparing an aldehyde by reacting a raw-C5 feed with a synthetic gas in the presence of a catalyst composition.

Hydroformylation method

The present specification provides a method for preparing 1,3-butadiene, the method comprising: (A) obtaining a first product comprising a light component, 1,3-butadiene, and a heavy component from a reactant comprising butene; (B) separating the heavy component from a second product comprising the 1,3-butadiene and the light component by condensing the heavy component after heat exchanging the first product; and (C) separating concentrated heavy component by reboiling the condensed heavy component.
