The patented new material, ITQ-55, is able to selectively adsorb ethylene over ethane as a result of its unique flexible pore structure. Built from heart-shaped cages interconnected by flexible elongated pore openings, the material allows the diffusion of the flatter ethylene molecules as opposed to the more cylindrical-shaped ethane molecules. The new material acts as a flexible molecular sieve."ITQ-55 is a very interesting material whose unique combination of pore dimension, topology, flexibility and chemical composition results in a highly stable and inert material that is able to adsorb ethylene and filter out ethane," said Professor Avelino Corma of the Instituto de Tecnologia Quimica and co-author of the research. "We are excited about this discovery and look forward to continuing our fruitful collaboration with ExxonMobil." Additional research must be conducted before the material can be considered for larger-scale demonstration and commercialization. Fundamental research will continue focusing on incorporating the material into a membrane and developing additional novel materials for gas separation. "Our ultimate goal of actually replacing cryogenic distillation is a long-term challenge that will require many more years of research and testing, in and out of the lab," said Gary Casty, section head for catalysis at ExxonMobil Research and Engineering Company. "Our next steps will focus on better understanding the full potential of this new zeolite material." Chemical plants account for about eight percent of global energy demand and about 15 percent of the projected growth in demand to 2040. As global populations and living standards continue to rise, demand for auto parts, housing materials, electronics and other products made from plastics and other petrochemicals will continue to grow. Improving industrial efficiency is part of ExxonMobil's mission to meet the world's growing need for energy while minimizing environmental impacts. ExxonMobil works with about 80 universities around the world to explore next-generation energy technologies. In 2016, ExxonMobil and the Georgia Institute of Technology announced the development of a potential new material focusing on liquids separation that could also reduce the amount of energy and emissions associated with manufacturing plastics. The results of this joint research were published by Science, as well.
