In recent years, there has been a significant movement in the fuel industry from dependence on petroleum to natural gas as an attempt to reduce anthropogenic CO<sub>2</sub> emissions. It has been shown that shale gas has a 23% lower life cycle greenhouse gas emission than gasoline. However, a significant challenge faced in harnessing natural gas is the lack of efficient storage and transportation infrastructure, resulting in significant flaring of industrial natural gas. In recent years, there has been an increasing interest towards employing Metal-Organic Frameworks(MOFs) as an adsorbent for natural gas to reduce flaring. A concept developed by our group, High Alkane Adsorbed Natural Gas (HAANG™), utilizes the presence of longer alkane chains in the untreated natural gas stream to improve the absorption efficiency of the material. Use of solid absorbents such as MOFs allows natural gas capture and storage without utilizing elevated pressures or low temperatures. For this system to perform optimally, traditionally microporous MOF materials need to be modified to accommodate the long alkane chains without compromising the high porosity and surface area of the material. This project looks as various methods of post-synthetic treatment of MOFs that optimizes its material properties for HAANG and the replication of these properties at industrially relevant scales.
