Abstract: The present invention successively performs hydrodeoxygenation (HDO) and dehydration so that, unlike that of a conventional technique, an alpha-olefin is prepared to have high selectivity, and not an olefin having a double bond at sites other than the alpha position. In addition, according to the present invention, selectivity for alpha-olefin can be further improved under optimal reaction conditions, and an alpha-olefin can be stably prepared with an extended preparation time of up to 180 hours.

Abstract: The present invention pertains to: an ethylene oligomerization catalyst containing a ligand compound; a catalyst composition employing same; and a method for producing an ethylene oligomer by using same. The catalyst exhibits excellent selectivity to oligomers and selectivity to 1-hexane, thus making it possible to mass-produce 1-hexane, which is an industrially useful chemical raw material, with high purity.

Abstract: Proposed are a coordination complex compound-ZIF complex and a method of preparing the same. More particularly, proposed are a coordination complex compound-ZIF complex, which is a complex on which a coordination complex compound is supported by being chemically and directly bonded to a metal vacancy site of a ZIF, capable of being usable as a heterogeneous catalyst that can be recovered and reused in subsequent processes and maintaining catalytic functions of the coordination complex compound, which is an active ingredient, and to a method of preparing the same.
