“…Barbooti et al conducted pyrolysis in a fixed bed batch reactor heated by an electrical furnace [55]. The effect of particle size (2, 6, 10, 16 and 20 mm) was studied at an optimum nitrogen flow rate of 0.35 m 3 /h and at various temperatures between 400-460 o C. It was found that solid residue yield increased when the particle sizes were increased.…”

Abstract−Waste tyres have become a grave concern as their accumulation is aggregating every year. Not only the size of waste tyre has to be reduced, but also some useful energy has to be recovered out of it as the world badly requires energy from alternate sources. Pyrolysis is one such method to extract energy potential products from waste tyres. It is extensively used to generate carbon black (solid product), tyre-oil (liquid product) and syngas (gas product) from waste tyres. In that connection, this article discusses the effect of various parameters on the product composition of pyrolysis of waste tyres. The current usage of pyrolysis products and their typical characteristics are also discussed in this critique. Of late, extraction of high value added products, such as activated carbon from carbon black, and limonene from tyre-oil is gaining attention. The article also throws some light on the application and generation routes of activated carbon and limonene from waste tyres.

“…The greatest amount of pyrolytic coke is formed at a low temperature during pyrolysis and with low heating rates (Sánchez et al, 2009). The other factors important in increasing the yield for the products of pyrolysis of organic materials are: the utilised carrier gas (Barbooti et al, 2004), retention time of gaseous products in the pyrolysis chamber (Islam et al, 2008), pressure (Bellais, 2007;Di Blasi et al, 2008;Williams and Slaney, 2007) and the construction of the pyrolysis facility (Arabiourrutia et al, 2007). The yield and properties of pyrolysis products can also be substantially influenced by the presence of catalyst and by the ratio of material/catalyst (Bellais, 2007;Boxiong et al, 2006).…”

The aim of this work was to determine the influence of liming on the process of pyrolysis. Three samples of sludge from two wastewater treatment plants were selected for this study on pyrolysis: sludge without liming and limed sludge from the Central Wastewater Treatment Plant in Ostrava and sludge from the Wastewater Treatment Plant in Sviadnov. The samples had different content of calcite (CaCO 3 ). The limed sludge contained 7% of CaCO 3 , sludge without liming 3.8% and sludge without liming from WWTP Sviadnov contained 0.5% of calcite. The results of laboratory pyrolysis proved that limed sludge released the maximum amount of carbon -55.46 %, while sludge without liming from WWTP Sviadnov released only 48.92%. Calcite produces during its decomposition CaO and the product influences the pyrolysis process because it supports cracking of volatile organic compounds

“…Carbon, solid char, oil and gas are produced by the pyrolysis of organic solid wastes (Lloyd, 2006). The solid char is a carbonaceous material which is used for the production of activated carbon (Gonzalez et al, 2009;Barbooti et al, 2004).…”

Footwear is a booming sector in Bangladesh. Disposing of process residues from the footwear industries, especially production waste of thermoplastic rubber and polyvinyl chloride soles as well as human used soles is a big concern due to its non-biodegradability. In this work, waste thermoplastic rubber (TPR) and polyvinylchloride (PVC) soles were used as an energy source through the fixed-bed-fire-tube heating pyrolysis to reduce the pollution load. The experiments were performed at varying temperature within the range of 250 0 C to 450 0 C at every 100 0 C interval for each case. In pyrolysis oil, char and gas were produced from the both TPR and PVC soles; temperature increment was created more percentage of oil from the both soles. At same condition TPR sole was produced 12.3% more oil than PVC sole. The pyrolytic oils were made fractional distillation; obtained liquids were relatively greater in volume and low boiling range. The obtained liquids from the fractional distillation were exhibited more light fractions present in the pyrolytic polyvinyl chloride oil (PPVCO) than pyrolytic thermoplastic rubber oil (PTPRO). The process could be optimized for the large scale, which will offer advantages to reduce the environmental impact as well as the production of new product from the waste soles.
