Chemical characteristics of oil-like products from hydrous pyrolysis of scrap tires at temperatures from 150 to 400 °C

► We used hydrous pyrolysis to study alteration products of scrap tire waste (STW). ► Two sets of experiments were conducted at T = 150-400 °C for 48 h. ► The first set included only STW and water and the second with oxalic acid (OA). ► The yields and alteration products increased with temperature and presence of OA. ► The results show that the yields are higher under reductive hydrous pyrolysis.
