摘      要：The separation of ethylene and ethane is a crucial,challenging and cost-intensive process in chemical ***-organic frameworks(MOFs)are a class of novel porous adsorbents used for the separation of ethylene/ethane ***,MOFs are normally crystalline powders that cause multiple problems,such as dust,abrasion and heat/mass loss,as well as significant pressure drops on the adsorption bed resulting in a sudden stop in *** solve these issues,we have prepared four different sphere-shaped adsorbents,including Mg-gallate,Co-gallate,MUV-10(Mn)and MIL-53(Al)using a calcium alginate method to achieve excellent ethylene/ethane separation *** performance of the sphere-shaped adsorbents has been validated using mechanical strength measurements,powder X-ray diffraction,scanning electron microscopy,thermogravimetric analysis,gas adsorption isotherms and dynamic breakthrough *** excellent mechanical strength of these sphere-shaped adsorbents meets the criteria for industrial application in gas ***,the energy consumption and operating cost will be further reduced in the ethylene production *** believe that this shaping method will open a prosperous route to the development of MOFs toward higher technology levels and their commercial application.
