Abstract: Slow rubber pyrolysis was performed at 300–500 °C in a horizontal batch mechanically fluidized reactor with 30–60 min holding time, and the products were characterized. The char (yield = 50%-wt) exhibited a high heating value (HHV) around 30 MJ/kg, comparable with bituminous coke, and 84%-wt Carbon. The gas products (yield = 24–31%) had a composition dependent on temperature: 21%-v ethylene, 46%-v propane, and 11%-v butane at 300 °C; over 20%-v hydrogen and methane at 400 °C; at 500 °C hydrogen ranged 46-69%-v and methane 21-36%-v. Oil products (yield = 17–22% yield) consisted of Keywords: Techno-economic assessment; Pyrolysis; Rubber; End-of-life tires (search for similar items in EconPapers)
