Abstract

A high-purity methane production system and production method which use two-phase anaerobic fermentation are disclosed. The high-purity methane production system can comprise: a waste storage tank for storing organic waste; a seed incubator comprising a first incubator, which receives the organic waste from the waste storage tank, and makes hydrogen-producing bacteria for hydrogen production become dominant by using the organic waste and cultures the same, and a second incubator, which makes methanogens for methane production become dominant by using the organic waste and cultures the same; a hydrogen production reactor for receives the organic waste received from the waste storage tank and the hydrogen-producing bacteria cultured in the first incubator, and produces hydrogen, carbon dioxide and an organic acid; a first methane fermentation tank receiving the hydrogen, the carbon dioxide and the organic acid, which were produced in the hydrogen production reactor, so as to produce methane; and a second methane fermentation tank receiving hydrogen and carbon dioxide, which remain after methane production, from the first methane fermentation tank and the methanogens cultured in the second incubator, so as to produce methane.

Abstract

The present invention relates to a method for producing a three-dimensional graphene composite, a three-dimensional graphene composite produced thereby, and a supercapacitor electrode comprising the same. In greater detail, three-dimensional crumpled graphene particles produced finely and uniformly even without a template can be produced on a mass scale in a short period of time and can be used in application to a supercapacitor electrode which is free from the problem of a conventional two-dimensional graphene production process wherein electrical and mechanical properties are lowered due to cohesion and lamination.

Abstract

The present invention relates to a power conditioning system (PCS) efficiency-considered microgrid operation device comprising: a scheduling unit for scheduling outputs of a controllable load, a battery, and an emergency internal combustion generator operated in a microgrid; and an operation control unit for controlling the operation of the battery, the emergency internal combustion generator, and the controllable load according to charging/discharging of the battery, the output or the emergency internal combustion generator, and the output of the controllable load, which have been scheduled by the scheduling unit, wherein the scheduling unit schedules charging/discharging by considering the efficiency of a PCS such that a mate of charge (SOC) of the battery is maintained within a preset range. According to the present invention, the microgrid can be efficiently operated by considering the charging/discharging efficiency of the PCS.
