“…There have been many studies on the pyrolysis of pure plastic materials [7,8] and mixtures of pure plastic which simulate those representative of real world samples such as municipal solid waste plastics [4,[9][10][11]. However, there are few studies detailing the product characteristics from the pyrolysis process of real world waste plastics [12,13]. In addition, there are no studies that the authors are aware of that investigate the detailed yield and composition of the pyrolysis products from real world waste electrical and electronic equipment.…”

Three plastic fractions from a commercial waste electrical and electronic equipment (WEEE) processing plant were collected and investigated for the possibility of recycling them by batch pyrolysis. The first plastic was from equipment containing cathode ray tubes (CRTs), the second plastic was from refrigeration equipment, and the third plastic was from mixed WEEE. Initially, the decomposition of each of the plastics was investigated using a TGA linked to a FT-ir spectrometer which showed that the CRT plastic decomposed to form aliphatic and aromatic compounds, the refrigerator plastic decomposed to form aldehydes, CO 2 , aromatic, and aliphatic compounds, and the mixed WEEE plastic decomposed to form aromatic and aliphatic compounds, CO 2 , and CO. Each plastic mixture was also pyrolysed in a batch reactor to determine the halogen and metal content of the pyrolysis products, additionally, characterisation of the pyrolysis oils was carried out by GC-MS and the pyrolysis gases by GC-FID and GC-TCD. It was found that the halogen content of the oils was relatively low but the halogen and metal content of the chars was high. The pyrolysis oils were found to contain valuable chemical products and the pyrolysis gases were mainly halogen free, making them suitable as a fuel.

“…The emitted hydrocarbon gases observed from the pyrolysis consist of alkane gases, methane, ethane, propane, and butane. Studies on the pyrolysis done at 430 °C of waste plastic mixtures have also been reported by Bhaskar et al [9], describing the yield of liquid, gas, and residue from municipal waste plastic as being 59, 25, and 16 % weight, respectively. There is a significant level of liquid yield from pyrolysis; similar results have also been reported by Lee and Shin [2] in their pyrolysis experiments conducted at 350 °C and 400 °C.…”

There has been a constant growth for plastic demand globally in the past decades, and the continuing expanding trend with rapid emerging economies has increased the concerns of many parties. Various approaches of recycling waste plastic including chemical recycling, thermal recycling, and mechanical recycling has been practiced. As chemical recycling is known to be a promising method in recovering hydrocarbon compounds, which can be used in high-end product, new avenues for waste recycling need to be established. Consumable carbon anodes are a major requirement for process used for producing primary aluminum. Since carbon is a main constituent of waste plastics, which have very low impurity levels, these clearly have the potential as a cheap readily available auxiliary source of carbon in carbon anodes. Coal tar pitch, a major by-product produced in petroleum refining, is the binder of choice for carbon anodes. Pitch penetrates the pores of petroleum coke-binding particulates and gets carbonized during the baking process. In-depth wettability and interfacial phenomena investigation was carried out to study interactions between polyethylene (PE) and petroleum coke (PC). The effect pyrolysis parameters on degradation process of PE have been characterized. The wettability study of polyethylene polymer on PC substrates has been carried out.

“…Para o estudo foram selecionados cinco resíduos poliméricos, considerados classe 1 por estarem contaminados com óleos e/ou produtos químicos, da unidade de produção PETROBRAS-40 (P-40), que opera no campo de Marlim Sul na bacia de Campos: embalagens plásticas (EP) vazias de produtos químicos, sacarias vazias de produtos químicos produzidos podem ser utilizados como insumo na indústria química; os sólidos apresentam propriedades combustíveis e adsorventes; e os gases podem ser reaproveitados em plantas de geração de energia elétrica, comumente denominadas plantas de co-geração Segundo Bhaskar et al (2003) [10] , a pirólise é o melhor método para preservar as reservas de petróleo e reduzir o descarte de recursos não degradáveis dispostos no meio ambiente. A utilização do óleo pirolítico proveniente do tratamento de resíduos plásticos como feedstock em refinarias tem apresentado bons resultados em escala piloto e semicomercial e tem representado uma das melhores tecnologias para a reciclagem de plásticos [11,12] .…”

Resumo:Resíduos plásticos gerados pelas atividades offshore da indústria de exploração e produção de óleo e gás, após caracterização por ensaio de identificação das classes poliméricas e análise térmica, foram pirolisados em atmosfera inerte a 450 °C. Os óleos pirolíticos foram caracterizados por espectrofotometria de infravermelho por transformada de Fourier (FTIR) e cromatografia em fase gasosa acoplada à espectrometria de massas (CG/EM), indicando a composição de parafinas, olefinas e aromáticos. Palavras-chave:Pirólise, resíduo offshore, caracterização de polímeros. Pyrolysis of Offshore Solid WastesAbstract: Solid wastes from oil and gas offshore exploration and production activities, after characterization of polymeric classes and thermal identification analysis tests, were pyrolysed under an inert atmosphere at 450 °C. The pyrolysis oil was characterized by Fourier Transform Infrared Spectroscopy (FTIR) gas chromatography mass spectrometry (CG/EM), indicating high generation of paraffin, olefines and aromatics.
