Abstract

The invention discloses a metal-organic framework material for methane adsorption and storage and a preparation method thereof. The metal-organic framework material is of a three-dimensional network structure formed by transition metal ions, an organic ligand, namely, 5,5'-(pyridine-2,5-diyl)-isophthalic acid, and derivatives of the ligand through coordinate bonds or intermolecular forces. The transition metal ions are preferentially selected from bivalent ions of copper, zinc, cobalt, nickel, cadmium and manganese. The metal-organic framework material is higher in specific surface area and pore volume and good in thermal stability. Pyridine, fluorine, methyl, amino, methoxy, hydroxyl, nitro and other functional groups which do not participate in coordination are introduced into the organic ligand used in the material, can effectively improve the capacity of methane adsorption and storage. The metal-organic framework material is simple in preparation process and low in cost, can be used repeatedly, has high capacity of methane adsorption and storage under variable-temperature and variable-pressure conditions, and is expected to be used as a novel high-efficiency methane adsorption and storage material.

Description

technical field

[0001] The invention relates to a metal organic framework material for methane adsorption and storage and a preparation method thereof, belonging to the technical field of metal organic framework materials. Background technique

[0002] Methane is a hydrocarbon with the chemical formula CH 4 , which is widely distributed in nature and is the main component of natural gas, biogas, oilfield gas and coal mine tunnel gas. Compared with other petroleum fuel gases, methane gas has a higher H / C ratio, so it is more suitable for use as combustion gas. Clean and reliable. At the same time, methane gas is also an important chemical raw material, which is widely used as a raw material for the production of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde. However, the problems of methane gas storage and transportation have become the main obstacles limiting its wide application. There are several ways to store methane gas, such as...
