“…Many authors gave TG curves for biomass, wood and different types of plastics [75]- [77], [80], [85], [89], [92], [100], [107], [116], [117], [119], [121]- [124]. Figure 6 gives the TG and DSC curves as a function of temperature of HDPE, PS, PVC and for poplar wood (PW) and a waste wood sample (W3).…”

“…This means that the experimental values, for example the gas, oil or char yield, or the gas composition, differ from those calculated by linear interpolation on the basis of the results for the pure components in the feedstock. The mechanisms of these synergistic effects were studied by different authors [75]- [77], [79], [80], [86], [89], [92], [96], [100], [102], [107], [115]- [117], [121], [122], [138], [145] . Plastics (PS, PE, PP, PET, PVC) devolatilise in a higher temperature range (300-500°C) than biomass (200-400°C) (see 3.2.…”

Over the past few decades, the sharp rise in post-consumer plastic and biomass waste has resulted in an ever growing challenge to treat such waste sustainably. Co-pyrogasification of plastics and biomass mixtures, as opposed to separately converting these waste streams, offers several advantages including an improvement in syngas quality and composition (H2/CO ratio) in relation to the desired application, and an easier reactor feeding of plastics. Furthermore, many studies have shown that co-pyrogasification promotes the conversion of waste to gas rather than char and tar. However, in order to achieve the desired product distribution or syngas composition, operating parameters such as the reactor temperature, equivalence ratio (air or oxygen), steam/fuel ratio and catalyst, have to be optimized. Thus, this paper aims to review literature studies on the co-pyrogasification of plastics and biomass by considering various aspects including the process principle, reactors, influence of feedstock characteristics and operating parameters on the products, as well as the synergies observed during the thermoconversion of plastics and biomass mixtures with some reference to coal mixtures when necessary.

“…It can be seen that the calorific value of liquid hydrocarbon increased when the value was compared with petroleum diesel. (Dewangan et al, 2016) also reported that it can be caused by the increase in H/C ratio. The Thermal Cracking of Low Temperature Conversion hydrocarbon content and oxygen content play a significant role in controlling the calorific value of oil.…”

Purpose-This work aims to study the treatment of adsorbant on the increasing liquid hydrocarbon quality produced by pyrolysis low density polyethylene (LDPE) plastic waste at low temperature. The hydrocarbon distribution, physicochemical properties and emission test were also studied due to its application in internal combustion engine. This research uses pure Calcium carbonate (CaCO 3) and pure activated carbon as adsorbant, LDPE type clear plastic samples with control variable that is solar gas station. Design/Methodology/Approach-LDPE plastic waste of 10 kg were vaporized in the thermal cracking batch reactor using LPG 12 kg as fuel at range temperature from 100 to 300°C and condensed into liquid hydrocarbon. Furthermore, this product was treated with the mixed CaCO 3 and activated carbon as adsorbants to decrease contaminant material. Findings-GC-MS identified the presence of carbon chain in the range of C6-C44 with 24.24% of hydrocarbon compounds in the liquid. They are similar to diesel (C6-C14). The 30% of liquid yields were found at operating temperature of 300°C. The calorific value of liquid was 46.021 MJ/Kg. This value was 5.07% higher than diesel as control. Originality/value-Hydrocarbon compounds in liquid produced by thermal cracking at a low temperature was similar to liquid from a catalytic process.

“…Igualmente em todos os estudos foi demonstrado que aumentos de temperaturas após atingido o valor máximo de rendimentos provocam a redução gradual do rendimento de bio-óleo. (ASADULLAH et al 2007;ISLAM, 2010ISLAM, e 2010MONTOYA, 2015;HENKEL, 2016;DEWANGAN, 2016). Alguns autores mencionam que ocorre um intenso craqueamento do BCA, geralmente em torno de 500ºC, e a temperaturas superiores se favorece a decomposição dos vapores e a ocorrência de reações secundárias de carbonização (ISLAM, 2010).…”

RESUMOO bagaço de cana-de-açúcar (BCA) é a biomassa lignocelulósica mais abundante no Brasil e se prevê um aumento da produção nos próximos anos, sendo uma promissora fonte na geração de energia elétrica e matéria prima para químicos e outros produtos de maior valor agregado. No entanto, o BCA possui algumas propriedades indesejáveis que limitam a sua conversão termoquímica eficiente, fazendo necessário a realização de pré-tratamentos antes da reação de conversão em produtos de maior valor energético e comercial. Neste artigo se presenta uma revisão bibliográfica sobre as propriedades físicas e químicas do BCA, assim como as técnicas utilizadas no pré-tratamento do bagaço e sua influência na obtenção de bio-óleo mediante a pirólise rápida. Os processos de secagem até uma umidade final menor do que 10%, a classificação pneumática em duas frações, a torrefação para melhorar suas propriedades mecânicas e energéticas, aumentando sua friabilidade, a pulverização para obter partículas com diâmetros menores do que 1mm, e a lixiviação para diminuir a quantidade de cinzas e aumentar o teor de celulose foram analisados como etapas de pré-tratamento do BCA com o objetivo de incrementar os rendimentos de bio-óleo durante a pirólise rápida.Palavras-chave: bagaço de cana-de-açúcar; pré-tratamento; pirólise rápida.
