(705a) Synthesis and Characterization of NOVEL MIXED Matrix Membrane Comprises of Bimetallic Metal Organic Framework for Separation of Carbon Dioxide from Methane

Earth’s population is increasing tremendously due to which the energy demand is also increasing abruptly. All this economic development and advancement in technology during the last century is based on our energy system. To fulfill demand for energy, fossil fuels are being used over a long time due to their high calorific value and availability. Upon combustion they produce large amount of carbon dioxide (CO₂) which readily enters in the environment and causes global warming and climate change.

Natural gas present in reservoirs is not in its purest form and a number of other impurities are present along with huge amount of carbon dioxide which needs to be separated to avoid corrosion in pipes and reduce compression cost. Various technologies are available for separation of CO₂ from natural gas. Among them membrane is the latest.

Mixed matrix membrane (MMM) is the modern membrane synthesis technique, the MMM is prepared by introducing different inorganic filler with superior selectivity and permeability into polymer matrix. MMM have shown huge potential for the separation performance of polymeric membrane

In this study, novel MMM was synthesized by introducing Zn/Co-ZIF composite MOF in PEBAX^®1657(block copolymers made up of rigid polyamide blocks and soft polyether blocks) and have been tested for the separation of CO₂ from CH₄ and N₂. Permeation test with different loading of in polymer were investigated, to find out the performance and behavior of the membrane with the increased filler quantity. Characterization techniques like XRD, SEM-EDS and FTIR, TGA, BET were carried out to gain essential and practical knowledge about materials and to correlate properties with structure and their results will be discussed.
