CATALYTIC DEPOLYMERISATION OF POLYMERIC MATERIALS
A process for converting a molten polymeric material is provided. The process includes effecting disposition of a molten polymeric material, having at least one carbon-carbon double bond, in sufficient proximity to a catalyst material within a reaction zone, to affect a reactive process that effects generation of a reaction product. The reactive process effects cleaving of at least one carbon-carbon double bond. The catalyst material includes [Fe—Cu—Mo—P]/Al.sub.2O.sub.3 prepared by binding a ferrous-copper complex to an alumina support to generate an intermediate material and reacting the intermediate material with a heteropolyacid.
Lubricant treatments for free-radical polymerizations
A process to prepare an ethylene-based polymer, said process comprising polymerizing a mixture comprising ethylene, at a pressure greater than, or equal to, 100 MPa, in the presence of at least one free-radical initiator; and in a reactor system comprising at least one reactor and at least one Hyper-compressor, and wherein at least one oil formulation, optionally comprising one or more lubrication agents, is added to the Hyper-compressor; and wherein at least one of the following steps takes place: A) thermally treating the one or more lubrication agents, in an oxygen-free atmosphere, to achieve a peroxide level ≤10 ppm, based on the weight of the lubrication agent(s), and then adding said agent(s) to the oil formulation, prior to adding the oil formulation to the Hyper-compressor; or B) thermally treating the oil formulation, in an oxygen-free atmosphere, to achieve a peroxide level ≤10 ppm, based on the weight of the oil formulation, prior to adding the oil formulation to the Hyper-compressor; C) a combination of A and B.
Method for efficiently regenerating waste lubricating oil
The present invention relates to a method for efficiently regenerating waste lubricating oil and belongs to the technical field of waste lubricating oil recovery and treatment. The method for efficiently regenerating waste lubricating oil is provided to solve a problem that existing waste lubricating oil has a high metal ion content. The method includes: adding the waste lubricating oil into a reaction vessel, performing a stirring treatment under the action of a cuprous-containing catalyst to form an aggregate, and then performing filtration and separation to directly remove the aggregate, to obtain corresponding regenerated lubricating oil. The present invention can effectively realize separation and removal of a metal ion, directly filter and separate, avoid emulsification, and obtain high quality lubricating oil having a low total metal ion content.
