Catalytic process for selective polyolefin hydrogenolysis
What is disclosed herein is a method for depolymerizing polyolefins, comprising a. preparing a catalyst comprising cobalt, nickel or both; b. combining the catalyst with a sample comprising polyolefins in a reaction vessel in the presence of H.sub.2 gas to produce a mixture, wherein the polyolefin comprises a carbon chain having the structure (CH.sub.2CHR).sub.n wherein R is an alkyl group and n is an integer greater than 20; c. reacting the mixture under conditions effective to depolymerize the polyolefins to produce decomposition products, wherein the decomposition products comprise the structure (CH.sub.2CHR).sub.m wherein m is an integer much less than n.
Footwear component manufacturing methods
Physical foaming a footwear component with a single-phase solution of a polymeric composition and a supercritical fluid is provided. The method include temperature conditioning a mold and then engaging the mold with a robot that conveys the mold to a press. At the press a gas counter pressure is applied to a cavity of the mold before injecting a single-phase solution of a polymeric composition and a supercritical fluid into the cavity of the mold. The process continues with releasing the gas counter pressure from the cavity of the mold and then removing the footwear component from the cavity of the mold. The parameters of the method are configured for the formation of the footwear component in an automated manner.
METHOD AND SYSTEM FOR THE ELIMINATION OF ODOURS IN RECYCLED PLASTICS
The invention relates to a method and system for the elimination of odours in recycled plastic materials, which comprises the steps of: separating and conditioning the plastic; shredding the plastic by means of a bladed shredded, which reduces the plastic into powder-sized particles; chemically washing with a surfactant, which is carried out in a stirring tank; rinsing the plastic material to eliminate dirt and the chemicals used, which is carried out in a rinsing reactor; mechanically drying the clean material in a dryer; and deodorising the plastic, wherein volatile organic compounds (VOCs) are removed from the clean, dry material by means of steam distillation, deodorisation being performed in a steam distillation column, the VOC-free plastic exiting through the bottom part of the column.
Recycling Eutectic Composition
The invention pertains to a recycling composition comprising a lactam and/or a eutectic composition comprising a lactam and a eutecting agent.
