Co-gasification of high-density polyethylene and pretreated pine wood

Co-gasification of biomass and plastic blends has been extensively studied, however the effect AAEMs (alkali alkaline earth metals) in on co-gasification behavior still remains unknown. Acid alkali pretreatment were used here to remove or introduce by ion-exchange method. SEM was obtain morphological characteristics three pretreated pine wood (PW) samples; TG analysis pure blend feedstocks examine decomposition behavior. CO2 assisted high-density polyethylene (HDPE) PW samples at different ratios conducted a fixed bed reactor, resulting flow rate yields H2, CO, light hydrocarbons (HC), total syngas, output energy determined. Synergetic effects from these during evaluated comparing experimental results with weighted individual components. Results showed that presence resulted increased char yield reactivity, enhanced syngas output. However, acid low AAEM content opposite trend. Irrespective pretreatment, synergistic found each component, its HDPE plastic. The synergy treated more pronounced high content, while those preferred fraction. highest 28.1, 34.3 30.1 kJ/g obtained water, fraction 44%, 22% 55%, respectively. Maximum 69% gasification 27% These help our understanding influence biomass-plastic mixtures. also achieve relatively stable for varying mixtures biomass.
