Kinetics of Polyethylene Terephthalate (PET)and Polystyrene (PS) Dynamic Pyrolysis
Thermo-chemical treatment (TCT) such as pyrolysis is getting recognized as a valid route for (i) materials and valuable products and petrochemicals recovery; (ii) waste recycling; and (iii) elemental characterization. Pyrolysis is also receiving renewed attention for its operational, economical and environmental advantages. In this study, samples of polyethylene terephthalate (PET) and polystyr...
متن کاملWaste Polyethylene Terephthalate (PETE) And Polystyrene (PS) Into Fuel
Waste plastics are harmful, toxic, and non-biodegradable. Environmental impacts of waste plastics are raised concern about all over the world for safe and friendly environment. Due to dense population and environmental effects of the major city in the world dumping, incineration and land filling are faced difficulties and challenges. At this circumstances vast of waste plastics are remained vul...
متن کاملLate Disruption of a Polyethylene Terephthalate Aortic Graft 30 Years after Initial Graft Placement
A 71 year old male who had undergone extra-anatomic bypass grafting between the ascending aorta and the thoraco-abdominal aorta at 41 years of age for aortic coarctation was admitted with back pain and dyspnea. A 16 mm Cooley double velour knitted polyethylene terephthalate (PET) graft was used in the initial operation in 1983. Computed tomography showed disruption of the initial PET graft perf...
متن کاملPreparation and Application of Dimer Acid/lignin Graft Copolymer
Dimer acid (DA) was grafted onto lignin (EHL) to form a graft copolymer DA-g-EHL. The selection of the reaction type and the optimization of the reaction conditions for the grafting reaction were conducted through orthogonal and single factor experiments. FT-IR and thermal analysis were used to characterize the graft product. It was found that, compared with free radical grafting, DA can be gra...
متن کاملPreparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization
A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...
