Abstract:
1. A method of obtaining high-quality products from polyolefin waste material or polyolefins, said method comprising the following steps in the order listed: (a) thermally or catalytically decomposing polyolefin waste material or polyolefins to yield vapor products; (b) condensing vapor products of thermal or catalytic decomposition of polyolefin waste material or polyolefins, to yield a first mixture; (c) catalytically hydrogenating said first mixture to reduce olefinic double bonds and acetylenic triple bonds to yield a second mixture; and (d) fractionally distilling said second mixture to yield one or more of the following: a kerosene fraction having a boiling range below 180° C., a cosmetic kerosene fraction having a boiling range of between 180 and 275° C., a white oil fraction having a boiling range of between 270 and 400° C., or a paraffin fraction having a boiling range above 400° C.
