Abstract

The invention discloses a method for preparing heterogeneous fuel oil by catalyzing waste polyolefin at low temperature through trace metal / molecular sieves. A method for preparing heterogeneous fuel oil by catalyzing waste polyolefin at low temperature through trace metal / molecular sieve comprises the following steps: adding pretreated waste polyolefin and a trace metal / molecular sieve catalyst into a reaction container, stirring and reacting for 0.5-24 hours at 200-350 DEG C in a hydrogen atmosphere with the hydrogen pressure of 0.5-5 Mpa, and collecting a heterogeneous fuel oil product after the reaction is finished. A traditional microporous molecular sieve is modified through a mechanical ball milling method, trace metal is loaded on the microporous molecular sieve, the accessibility of long-chain alkane molecules of waste polyolefin, loaded metal particles and molecular sieve acid sites is improved, the metal loading amount is saved, and meanwhile hydro-conversion of polyolefin to isomerous fuel oil is greatly promoted.
