Abstract: Methods for the oligomerization of ethylene, and more specifically, methods for the preparation of mainly ethylene oligomers of C10 or higher are described. A method can include performing a first oligomerization of an ethylene gas using a Ni-containing mesoporous catalyst, followed by a second oligomerization using an ion exchange resin, etc. to produce ethylene oligomers of C10 or higher. The method for the preparation of ethylene oligomers can produce C8-16 ethylene oligomers in high yield without inducing deactivation of the catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.

Abstract: A reaction apparatus includes first and second reaction material accommodation parts, each of which accommodates a solid, gaseous, or liquid reaction material. A feed pump feeds the reaction material to one or each of the first and second accommodation parts. A reactor mixes the reaction material fed from the feed pump. The reactor is configured to have a cylinder that has a reaction chamber which accommodates the reaction material therein. The reactor has injection ports on which one side of each of the upper portion and lower portion thereof are connected to the first and second reaction material accommodation parts, respectively. A stirring shaft is disposed to be rotatable in the cylinder and stirs the reaction material supplied from the first and second reaction material accommodation parts. A stirring motor provides torque for the stirring shaft.

Abstract: A catalyst for effectively removing NOx by using NH3 as a reducing agent is disclosed. Particularly, a vanadia impregnated onto Ti-PILC (titania-pillared interlayer clay) is disclosed, which is prepared by the generally known technology. More specifically, a V2O5/Ti-PILC catalyst is disclosed, in which NOx contained in the flue gas from an electric power plant and the like (an excessive amount of SO2 being present in the flue gas stream) is reacted with NH3 (which is injected as a reducing agent) over a vanadia impregnated onto a Ti-PILC, so that they can be converted into harmless nitrogen and water. The V2O5/Ti-PILC catalyst is employed for reducing NOx contained in the exhaust gas stream as well as the large amounts of SO2 into nitrogen and water. The catalyst is prepared by pillaring a titania to a clay by a pillaring method.
