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.

A method of producing earthworm castings by feeding earthworms with feed prepared by mixing solid fuel ash with shells, crab shells and yellow earth and to an earthworm bed for producing earthworm castings, comprises the steps of: grinding solid fuel ash; washing shells and crab shells to remove salt, and then removing 80% or more of water therefrom; grinding the washed shells and crab shells; mixing 60-70 wt % of yellow earth, 20-30 wt % of the solid fuel ash and 10-20 wt % of the ground shells and crab shells; fermenting and maturing the mixture; and feeding the matured mixture to earthworms to allow the earthworms to produce earthworm castings. The earthworm bed () comprises: a feeding unit () through which feed prepared by mixing solid fuel ash with shells, crab shells and yellow earth is fed; a breeding chamber () in which earthworms are bred to produce earthworm castings; and a discharge unit () through which the earthworm castings produced in the breeding chamber () are discharged. According to the invention, ash from a solid fuel boiler is used as feed for earthworms to produce earthworm castings, whereby problems associated with the disposal of the solid fuel ash are solved in an environmentally friendly and economical manner. The produced earthworm castings are used as fertilizers, solid amendments and the like.
