ABSTRACT:
Melting and cracking of amorphous polyolefin are carried out with a relatively small quantity of heat consumption and also with easiness in separating sludge, in converting it into oil by maintaining amorphous polyolefin at a high temperature of about 130.degree. - 300.degree.C for a relatively long time alone or together with a petroleum hydrocarbon oil to reduce the viscosity of the resultant melt to 5 - 250 CP, spraying the resultant melt upon lumps of amorphous polyolefin, separating impurities in the lumps as sludge, cracking the resultant molten mixture at a temperature of about 250.degree. - 450.degree.C and recovering oily products. For that purpose an apparatus comprising a combination of a holding tank for melt of amorphous polyolefin, a vessel for melting amorphous polyolefin equipped with a perforated plate or a wire-netting, a revolving shaft, a stirrer, etc. and a thermally cracking vessel equipped with a stirrer, a distillation means, and auxiliary means such as heating furnaces, pumping means for the melt and heating medium, is used.
