Mixed plastics of polypropylene (PP), polyethylene (PE), and polystyrene (PS) show positive synergistic effects during co-pyrolysis, lowering activation energy. Introducing spent FCC catalysts further reduces pyrolysis temperature and activation energy while increasing thermal degradation rate. Compared with non-catalytic pyrolysis, the maximum weight-loss rate occurs ~12 K earlier, degrades ~41% faster, and average activation energy decreases by ~22 kJ/mol. Ball milling modification outperforms ultrasonic treatment, supporting improved catalytic efficiency via kinetic and thermodynamic analysis.","cbCainqwSHUAhtNK","https://ap.wps.com/l/cbCainqwSHUAhtNK","pdf",3677106,1,16,"English","en","# Introduction\n## Abstract\n## Background and motivation","[{\"question\":\"Why does the study use thermochemical pyrolysis for waste plastics?\",\"answer\":\"Thermochemical methods are identified as a highly promising way to treat waste plastics, and the study focuses on reducing the energy demand of pyrolysis.\"},{\"question\":\"What is the effect of co-pyrolysis of PP, PE, and PS in this study?\",\"answer\":\"Kinetic calculations indicate a positive synergistic effect in mixed-plastics co-pyrolysis, which helps reduce activation energy.\"},{\"question\":\"How do spent FCC catalysts and their modification methods influence catalytic pyrolysis performance?\",\"answer\":\"Spent FCC catalysts reduce both pyrolysis temperature and activation energy while increasing the thermal degradation rate; ball milling modification performs better than ultrasonic modification, improving catalytic efficiency.\"}]",1780002092,40,{"code":4,"msg":28,"data":29},"ok",{"site_id":30,"language":22,"slug":31,"title":13,"keywords":32,"description":14,"schema_data":33,"social_meta":84,"head_meta":86,"extra_data":88,"updated_unix":25},105,"study-on-kinetics-of-spent-fcc-catalyst-applied-to-the-living-waste-plastics","",{"@graph":34,"@context":83},[35,52,66],{"@type":36,"itemListElement":37},"BreadcrumbList",[38,42,46,49],{"item":39,"name":40,"@type":41,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":43,"name":44,"@type":41,"position":45},"https://docshare.wps.com/document/","Document",2,{"item":47,"name":12,"@type":41,"position":48},"https://docshare.wps.com/document/research-report/",3,{"item":50,"name":13,"@type":41,"position":51},"https://docshare.wps.com/document/study-on-kinetics-of-spent-fcc-catalyst-applied-to-the-living-waste-plastics/31716/",4,{"url":50,"name":13,"@type":53,"author":54,"headline":13,"publisher":56,"fileFormat":59,"description":14,"dateModified":60,"datePublished":60,"encodingFormat":59,"isAccessibleForFree":61,"interactionStatistic":62},"DigitalDocument",{"name":9,"@type":55},"Person",{"url":39,"name":57,"@type":58},"DocShare","Organization","application/pdf","2026-05-28",true,{"@type":63,"interactionType":64,"userInteractionCount":4},"InteractionCounter",{"@type":65},"ViewAction",{"@type":67,"mainEntity":68},"FAQPage",[69,75,79],{"name":70,"@type":71,"acceptedAnswer":72},"Why does the study use thermochemical pyrolysis for waste plastics?","Question",{"text":73,"@type":74},"Thermochemical methods are identified as a highly promising way to treat waste plastics, and the study focuses on reducing the energy demand of pyrolysis.","Answer",{"name":76,"@type":71,"acceptedAnswer":77},"What is the effect of co-pyrolysis of PP, PE, and PS in this study?",{"text":78,"@type":74},"Kinetic calculations indicate a positive synergistic effect in mixed-plastics co-pyrolysis, which helps reduce activation energy.",{"name":80,"@type":71,"acceptedAnswer":81},"How do spent FCC catalysts and their modification methods influence catalytic pyrolysis performance?",{"text":82,"@type":74},"Spent FCC catalysts reduce both pyrolysis temperature and activation energy while increasing the thermal degradation rate; ball milling modification performs better than ultrasonic modification, improving catalytic efficiency.","https://schema.org",{"og:url":50,"og:type":85,"og:title":13,"og:site_name":57,"og:description":14},"article",{"robots":87,"canonical":50},"index,follow",{"doc_id":7,"site_id":30}]
