Abstract

The present invention discloses a device for coal-derived bio-methane and a method thereof, and belongs to the technical field of biosynthesis. The device for coal-derived bio-methane comprises a reaction kettle, an anaerobic device, a feeding device and a separation device. The anaerobic device comprises a nitrogen gas cylinder and a vacuum pump. The feeding device comprises a nutrient solution bottle and a bacterial liquid bottle. The separation device comprises a separation kettle. The nitrogen gas cylinder, the nutrient solution bottle, the bacterial liquid bottle, the vacuum pump and the separation kettle are respectively connected with the reaction kettle. The coal-derived bio-methane is prepared by adopting the above device. According to the technical scheme of the invention, a bacterial liquid and a nutrient solution are respectively added in a coal sample, and then the bio-methane is prepared after the reaction of above materials. In this way, in the big coal sample environment, the in-situ anaerobic condition, the temperature, the pressure and the like of a coal seam are simulated. As a result, the in-situ real condition of the coal seam can be reflected to a greater degree. Moreover, the device and the method have important significance on the in-situ applications of coal-derived bio-methane.

Description

technical field [0001] The invention relates to a device and method for producing biomethane from coal, belonging to the technical field of biosynthesis. Background technique [0002] At present, coal accounts for about 30% of the world's primary energy consumption and more than 70% of my country's primary energy consumption. However, direct combustion of coal has low calorific value, high pollution, and high transportation costs. How to realize the efficient, clean and green utilization of coal is the main factor restricting the development of the coal industry and the focus of coal utilization. Microorganisms can convert coal into biomethane in situ in the coal seam, thereby converting it into coalbed methane, a clean energy source. The in-situ conversion of coal to biomethane does not consume additional energy and has no environmental pollution. It can effectively overcome a series of problems in the direct combustion of coal and realize the clean and green utilization ...
