Functional Composite Adsorbents Based on Metal-Organic Frameworks in a Carbon Matrix Applied for Methane Storage
Protection of Metals and Physical Chemistry of Surfaces(2019)
摘要
In the present work, a method for producing new shaped composite materials by introducing a metal-organic framework structure Cu-BTC110 into a matrix of carbon material has been suggested. Powdered microporous activated carbons prepared from vegetable, polymer, and peat raw materials were used as carbon matrices. Physicochemical properties and structure-energy characteristics of the initial materials and shaped composites based on them were determined. It was demonstrated that the Cu-BTC110 composite with active carbon prepared from peat enabled one to achieve a balance between structure-energy characteristics, mechanical characteristics, and methane adsorption capacity. Depending on the temperature, the amount of accumulated methane can achieve 160–200 m 3 (NTP)/m 3 within a pressure range from 3.5 to 10.5 MPa.
