Diesel oil from residual materials by catalytic depolymerisation comprising energy input by means of a pump-stirrer system

摘要

Diesel oil is produced from feed oil containing hydrocarbon-containing residues by heating residue-containing feed oil by converting some of flow energy into heat; separating solids from the residue-containing feed oil; distilling the residue-containing feed oil to produce a distillate; and producing diesel oil from the distillate. Production of diesel oil from a feed oil containing hydrocarbon-containing residues sequentially involves: (A) producing a feed oil flow having a flow energy; (B) inputting hydrocarbon-containing residues into the feed oil; (C) heating the residue-containing feed oil by converting some of the flow energy into heat; (D) separating solids from the residue-containing feed oil; (E) distilling the residue-containing feed oil to produce a distillate; and (F) producing diesel oil from the distillate. An independent claim is also included for a system for producing diesel oil from a feed oil containing hydrocarbon-containing residues comprising: (A) high-pressure pump (1) for providing a flow of feed oil; (B) agitator (7) moving in the flow oppositely to the direction of flow from the pump; (C) throttle valve for regulating the flow downstream of the agitator; (D) separating cyclone downstream of the throttle valve and having a pair of output ports; (E) discharge screw (20) in one of the output ports; and (F) distillation unit (17) in the other output port.
