The present disclosure relates to a catalyst for ammonia decomposition, a manufacturing method therefor, and a method for producing hydrogen using the same. More particularly, the present disclosure relates to a catalyst for ammonia decomposition, a manufacturing method therefor, and a method for producing hydrogen using the same, in which by manufacturing a catalyst for decomposition of ammonia using a solvothermal synthesis method to which alcohol is applied, an ammonia conversion rate can be improved due to excellent catalytic activity in an ammonia decomposition reaction, and hydrogen can be efficiently produced from ammonia due to long-term stability even at a high temperature and for long periods of time.

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.

The present invention relates to a zeolite catalyst for preparing light alkene by dehydrogenation of light alkane including a cocatalyst metal selected from tin (Sn), germanium (Ge), lead (Pb), gallium (Ga) and indium (In), and a preparation method of the same. The catalyst of the present invention is prepared by using the zeolite having a relatively high pore diameter, a structure of at least 12-membered ring, and a low acidity due to a SiO/AlOratio of at least 50, so that it can suppress the inactivation of a catalyst caused by pore clogging due to the formation of coke. Therefore the catalyst of the present invention can be effectively used as a catalyst for the preparation of light alkene by dehydrogenation of light alkane.
