Abstract: The present invention provides an integrated system comprising: an electrocatalysis device, in which an oxidation reaction is carried out at an anode by an electrocatalysis of glycerol, and at a cathode hydrogen is produced through a reduction reaction; and a chemical catalysis device for producing butene oligomers from lignocellulosic biomass through a hydrogenation process, wherein the hydrogen produced by the electrocatalysis device is used for the production of the butene oligomers by the chemical catalysis device, and a thermal energy of the electrocatalysis device and the chemical catalysis device is exchanged with each other. The integrated system according to the present invention can reduce the cost of materials of a process for preparing butene oligomers by using hydrogen, which is a byproduct of a process for preparing glycerol derivatives, as a material of a process for preparing the butene oligomers through the integration of materials and energy from the processes for preparing glycerol derivatives and butene oligomers, and can obtain an effect of reducing energy costs by greatly reducing energy required in an integrated process by supplying, as a part of a thermal energy required at the process for preparing glycerol derivatives, the waste heat of the process for preparing the butene oligomers through the construction of a thermal energy integration network.

Abstract: A catalyst for an ammonia decomposition reaction and a hydrogen production method using the catalyst are proposed. The shape of cerium oxide used as a catalyst carrier for the catalyst is controlled, and cesium (Cs) is included in the catalyst as a catalyst enhancer. Thus, the catalyst increases an ammonia conversion rate and has improved long-term stability.

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.
