Transforming Naphtha Steam Crackers for Plastic Waste and Biogenic Feedstocks by Henrik Thunman in Progress in Petrochemical Science Abstract: In an era where sustainability and profitability are crucial, conventional naphtha steam crackers are increasingly challenged by competing processes and stringent environmental regulations. A pioneering approach from Chalmers University of Technology in Sweden presents a promising solution. This innovative method also addresses the inefficiencies of current plastic recycling methods and paves the way for the transition toward a circular economy. The rise of low-cost alternative feedstocks like ethane and LPG, combined with advanced processes like CATOFIN® PDH that offer high selectivity for olefins directly from alkanes, has led to an oversupply of olefins in the petrochemical market. Additionally, the increasing costs associated with fossil CO2 emissions make naphtha steam crackers less competitive than alternative olefin production methods, wh...
