“…Mogą również pojawić się w nim substancje żywiczne. Wartość opałowa oleju pirolitycznego wynosi około 40 MJ/kg, lepkość od 7 mm 2 /s do 36,2 mm 2 /s, gęstość od 0,880 g/cm 3 do 1,100 g/cm 3 [5]. Ponieważ w procesie wulkanizacji gumy jednym z najistotniejszych składników jest siarka, to oleje pirolityczne uzyskiwane z opon charakteryzuje duża jej zawartość -nawet powyżej 1% (m/m).…”

Zarządzanie emisją z olejów opałowych zawierających frakcję oleju popirolitycznego Artykuł przedstawia możliwości wykorzystania frakcji popirolitycznej jako samoistnego paliwa lub jako komponentu olejów opałowych na podstawie uzyskanych wyników z badań i pomiarów emisji składników gazowo-pyłowych do atmosfery. Zarządzanie powstającymi emisjami pozwoli uzyskać informację na temat przebiegu procesu spalania skomponowanych paliw (zawierających frakcję popirolityczną) oraz porównać wielkości emitowanych zanieczyszczeń tego typu paliwa z tradycyjnymi olejami opałowymi.Słowa kluczowe: emisja zanieczyszczeń do atmosfery, olej popirolityczny, piroliza zużytych opon. Managing emissions from heating fuels containing a fraction of post-pyrolithic oilThe article presents the possibility of using a post-pyrolithic fraction as a spontaneous fuel, or as a component of heating fuels, based on the obtained measurements of emission of gaseous and particulate components into the atmosphere. Management of the resulting emissions will allow to obtain information on the combustion process of the composed fuels (containing postpyrolithic fraction) as well as the comparison of the amount of pollutants by this type of fuel with conventional heating oils.Key words: emission of pollutants into the atmosphere, post-pyrolithic oil, pyrolysis of used tires.

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 combustion of coal for power generation will continue to play a major role in the future, however, this must be achieved using cleaner technologies than we use at present. Scrap tyre arisings in the UK are 400,000 tonnes per year amounting to 30 million tyres and in the EU as a whole, more than 2.5 million tonnes of tyres per year are scrapped. The recent EC Waste Landfill Directive (1999) sets a deadline for the banning of whole and shredded tyres from landfill sites by 2006. Consequently, there is an urgent need to find a mass disposal route for tyres. We describe, in this paper, a novel use for tyre rubber pulverized fuel in a NOx reburning process which may have an application in power station boilers. This method of disposal could represent a way of combining waste disposal, energy recovery and pollution control within one process. A preliminary study of micronised tyre combustion was undertaken to identify the suitable size ranges for application in NOx reduction by reburning. Tests were performed in a down-fired, pulverised fuel combustor (PFC) operating at about 80kW. Superior combustion characteristics i.e. burnout were achieved with particle sizes less than 250 µm. A South African coal was used as the primary fuel in the reburn tests and the tyre was fed pneumatically via a separate feed system. Parameters studied, were, reburn zone stoichiometry and reburn fuel fraction. Additionally, the carbon content of the ash was carefully monitored for any effect on burnout at the fuel-rich reburn stoichiometries. The NOx reductions achieved with tyres are compared with reburning with coal. NO x reductions up to 80% were achieved with tyres at half of the reburn fuel feed rate required to achieve the same reductions by coal. The results have been evaluated within the context of other studies available in the literature on NOx reburning by bituminous coal, brown coal, gas and biomass.
