“…Furthermore, this catalytic behavior holds both for studies where a separate catalytic bed was used [37,[49][50][51][65][66][67], and for studies where the catalyst was present in the pyrolysis reactor itself (in-situ) [37,[68][69][70]. Apart from these acidic catalysts, only a few other catalysts have been investigated, see Table 6.…”

“…Most of these studies use acidic catalysts (various types of zeolites), see Table 5 [31,37,[49][50][51][65][66][67][68][69][70]. Generally, the objective (and the result) of the usage of this type of catalyst is an increase in the yield of single-ring aromatics.…”

“…Also, they obtained 49.2 wt % oil using 10% catalyst at 485 • C, whereas the oil yield was 39.6 wt % in the same condition without using a catalyst. Tyre pyrolysis at 430 • C with the catalyst mixture of ZSM-5 and lubricant base oil (LBO) was carried out by Qu et al [142]. The mixture of two catalysts significantly increased the degradation rate.…”

Scrap Tyre Management Pathways and Their Use as a Fuel—A Review

2016

Abstract:This article provides a review of different methods for managing waste tyres. Around 1.5 billion scrap tyres make their way into the environmental cycle each year, so there is an extreme demand to manage and mitigate the environmental impact which occurs from landfilling and burning. Numerous approaches are targeted to recycle and reuse the tyre rubber in various applications. Among them, one of the most important methods for sustainable environmental stewardship is converting tyre rubber components into bio-oil. In this study, scrap tyre management techniques including landfill, retreading, recycling, combustion, and conversion to liquid fuels was reviewed (including gasification, hydrothermal liquefaction, and pyrolysis). The effects of parameters such as reactor types, pyrolysis temperature, and catalyst on the oil, gas and solid products in pyrolysis process were investigated.

“…Brindle, 2002a, 2003) have reported that Y-zeolite increases the yield of benzene, toluene, xylenes, ethyltoluenes, trimethylbenzenes, and tetramethylbenzenes when scrap tires are pyrolysed, they also reported increased yields of naphthalene and substituted naphthalenes. Some work has been published where zeolite catalysts were found to have little effect on the pyrolysis of tires (Qu et al, 2006).…”

“…Although the liquid pyrolysis products of natural rubber might have some value as a fuel and limonene has many uses in the chemical industry, it would be more economical to convert the isoprene oligomers into more valuable chemical products. Several investigations have been carried out into catalytically upgrading pyrolysis products and one of the most promising types of catalysts are zeolites, which have been used to upgrade the pyrolysis products of a wide variety of materials (Bagri and Williams, 2002;Miskolczi et al, 2006;Olazar et al, 2000;Williams and Nugranad, 2000), including rubber tyres (Qu et al, 2006;Shen et al, 2007a;Shen et al, 2007b;Shen et al, 2006;Williams and Brindle, 2002a, 2002b, 2003.…”

Pyrolysis of latex gloves in the presence of Y-zeolite

2009

View full text Add to dashboard Cite

In this study we have investigated the possibility of processing waste rubber gloves using pyrolysis. Y-zeolite catalyst was employed to upgrade the pyrolysis products to give higher yields of valuable aromatic compounds such as toluene and xylenes. The composition of the pyrolysis products was determined using GC-MS, GC-FID, GC-TCD, and FT-IR. It was found that when rubber gloves were pyrolysed in the absence of a catalyst, the pyrolysis oil consisted mainly of limonene and oligomers of polyisoprene. When Y-zeolite was added to the reaction system, the yields of toluene, xylene, methylbenzenes, ethylbenzenes, and naphthalenes increased dramatically. The Y-zeolite also catalysed the decomposition of limonene, which was absent from the catalytic pyrolysis products. The presence of the Yzeolite catalyst also increased the yield of hydrocarbon gases. The tests were carried out at both 380°C and 480°C and it was found that the higher reaction temperature led to increased yields of all the major compounds, both in the presence and absence of the Y-zeolite catalyst.
