    Abstract: Process for the preparation of ethylene homopolymers or copolymers in a high pressure reactor with at least two spatially separated initiator injection points by polymerizing ethylene and optionally further monomers in the presence of at least two different mixtures of free-radical polymerization initiators at from 100° C. to 350° C. and pressures in the range of from 160 MPa to 350 MPa, wherein the process comprises the following steps: a) providing at least two different initiators as solution in a suitable solvent or in liquid state, b) mixing the initiators and optionally additional solvent in at least two static mixers and c) feeding each of the mixtures to a different initiator injection point of the high pressure reactor, and apparatus for feeding initiator mixtures to a high pressure reactor with at least two spatially separated initiator injection points.

    Abstract: Equipment and a process for upgrading oil are provided to produce a refined oil lighter than a material oil by cracking the heavier material oil with the addition of hydrogen under relatively relaxed production conditions. An equipment for upgrading oil according to one aspect of the invention includes an emulsion making portion (10), a refinery tank portion (20), and a heating portion (30), and configured to make an emulsion (E) by emulsifying ionized alkaline water (A) in a material oil (O1) in the emulsion making portion (10), and to drop droplets (D) of the emulsion (E) onto the surface (S) of a heat medium (O2) in the refinery tank portion (20) heated by the heating portion (30).
