METHOD FOR PREPARING BUTADIENE THROUGH OXIDATIVE DEHYDROGENATION

摘要

The present invention relates to a method for producing butadiene through an oxidative dehydrogenation reaction. The production method according to the present invention may easily regulate an input ratio between oxygen and nitrogen that are used as raw material, such that a loss may be minimized of butadiene that is included in a second fraction stream (purge stream) and discharged to outside of the system. Consequently, an economic competitiveness of the process, such as a reduced raw material cost and an improved productivity may be realized.
