core tip: silicalite adsorbents discovered by scientists at the Spanish Institute of science and Technology (ITQ; Valencia) and ExxonMobil (German, European) can eventually reduce the carbon footprint of food containers, garbage bags, water bottles and other plastic products. The energy and carbon dioxide emissions required for ethylene separation can significantly reduce the energy and emissions related to ethylene production by 25%. The research on patent materials has been published in the peer-reviewed journal Science

[China Packaging News] scientists from the Spanish Institute of science and Technology (ITQ; Valencia) and ExxonMobil (Irving, Germany) found that silicalite adsorbents can eventually reduce the carbon footprint of food containers, garbage bags, water bottles and other plastic products. The energy and carbon dioxide emissions required for ethylene separation can significantly reduce the energy and emissions related to ethylene production by 25%. The research on patent materials has been published in the peer-reviewed journal Science

zeolite is a porous material often used as adsorbent and catalyst in chemical processes. According to the research of researchers, who can use silica zeolite heart-shaped cages with unique structure in the process of gas separation? These cages are connected with each other through flexible long pore openings, such as recycling ethylene from ethane, which has unprecedented selectivity at ambient temperature. The new material was characterized as flexible molecular sieve

"itq-55 is a very interesting material. Its unique pore size and topology need not only fundamental transformation from the plastic granulator process, but also the combination of structure, flexibility and chemical composition to form a highly stable and inert material, which can adsorb ethylene and filter out ethane." Professor Avelino corm of the Institute said, "we are excited about this discovery and look forward to continuing our fruitful cooperation with ExxonMobil."

more research is needed before materials are commercialized, but in terms of energy efficiency and sustainability of plastic processors, it may become a technology that changes the rules of the game

according to ExxonMobil statistics, chemical plants account for about 8% of global energy demand, which is expected to increase by about 15% in 2040. With the continuous improvement of global population and living standards, the demand of plastics and other petrochemical products for auto parts, housing materials, electronics and other products will continue to grow after comparing the packing list to check whether the testing machine and accessories are complete and intact

the company said that improving industrial efficiency enables ExxonMobil to meet the growing global energy demand while minimizing environmental impact
