Oxidative thermal degradation of LDPE and the determination of some thermodynamic quantities

“…Experiments were carried out using a set-up [17] at atmospheric pressure and condensed products from this system were measured and the yield of liquid products and conversion was calculated by Eqs. (1) and (2):…”

“…In general polymers are bioinert; so they have been high resistant to assimilation by microorganisms such as fungi, bacteria and like. It has been observed that the oxidation products of polyolefins are biodegradable [12][13][14][15][16][17]. Since commercial polyolefins have relatively high molar mass values, there are very few ends of molecules accessible on or near the surfaces of materials made from these resins.…”

Catalytic and thermal oxidative pyrolysis of LDPE in a continuous reactor system

“…During experiments, the acid number (the ASTM D 1386 definition of acid number is the milligrams of potassium hydroxide necessary to neutralize one gram of organic matter [20]) of liquid products was performed to indicate the amount of free carboxylic acid, and peroxide number which indicates oxidation grades was also determined. Liquid products were analysed using a Thermo Finnigan GC/MS Quadropole apparatus with a 30 m capillary column containing 5% diphenyl and 95% diphenyl polysiloxane (the injection temperature was 200 8C, the initial temperature 40 8C, the initial waiting time 10 min, the heating rate 10 8C min À1 , the end temperature 300 8C, the final hold time 10 min, and the gas flow rate 0.7 mL min À1 He).…”

“…A number of authors have reported that the best recycling methods of waste plastics are catalytic and non-catalytic degradation processes, furthermore, recycling of thermoplastics can append to solve pollution problems [1,2,20]. In general of the world, especially in developed countries, the solid wastes are a series problem and these countries have developed a variety of methods for wastes evaluation [2,3].…”

Co-pirólise de resíduos de polietileno com gasóleo pesado da Bacia de Campos

“…Nos aterros, além de dificultar a compactação do lixo, a impermeabilidade do plástico dificulta as trocas gasosas, criando barreiras para a decomposição dos materiais biodegradáveis [5] . Diferentes alternativas estão sendo consideradas para a redução do impacto ambiental de resíduos plásticos [5,6] . No Brasil, a reciclagem mecânica é a mais utilizada.…”
