POLYMER-GRADE OLEFIN PRODUCTION BY GAS-PHASE SMB

摘要

Petrochemicals play a vital role in the chemical and petroleum industry due to their utilization as a base product for the fabrication of a wide range of materials. In fact, these substances have the ability to react with themselves, to serve as starting/intermediates, to create innovative products, which are used in numerous processes, in several industries all over the world, from pharmaceuticals and cosmetics, to all kinds of plastics and textile. Moreover, the production of olefins, mainly ethylene and propylene, has been increasingly important worldwide. These olefins have a great number of commercial applications, particularly in the manufacture of polyethylene and polypropylene, the world's most widely used polymers.
