“…Moreover, the sulfur contents in the gas product are lower in co-gasification than those in gasification of lignite alone. 118 Gasification of natural rubber can be conducted at 800°C to 900°C. Rubber can also be employed for coal co-gasification because it reduces sulfur content in the gas product and improves the calorific value.…”

Natural rubber is a tropical plantation crop that mainly consists of hydrocarbon polyisoprene (cis-1,4-polyisoprene). Rubber can be converted through depolymerization into liquid, which can be used as fuels or chemical feedstock. This paper provides information on natural rubber and its alternative sources worldwide. Although we focus on hydrous pyrolysis, we also introduced various depolymerization processes, including pyrolysis, gasification, chemical degradation, catalytic cracking and hydrogenation. Hydrous pyrolysis improves the depolymerization process, such that raw materials can be fed without requiring a drying process. This process can also be conducted at low temperatures, and water can be solely used as reaction medium and can be easily separated from the oil product. This paper also reviews the role of process parameters such as temperature, rubber to water ratio, reaction time, and type of gases on product quality and quantity. Moreover, this study highlights the environmental and economic feasibility of hydrous pyrolysis.

“…The first is used to determine the composition of the hydrocarbon: Clarus 500, Perkin Elmer, equipped with a flame ionization detector (FID), Porapak-Q, 100÷120 mesh, 2 m long, 2.1 mm in diameter. Each time it was injected 200 mm 3 gas sample. The analysis was carried out at a constant temperature of 105ºC.…”

“…Liquid fraction could be great source of energy the GCV (Gross Calorific Values) value is about 42 MJ/kg, and also the sulfur content is about 1% -it is within the European standard for heating fuels [2]. Use moderate temperature regime (300÷500ºC) producing mainly pyrolytic oil, while at high temperatures (500÷900ºC) is preferable to produce the gas [3,4]. Roy [5] reported that pyrolysis product yields is 52.5 wt.% solid residue, 27.7 wt.% organic liquids, 13.3 wt.% pyrolytic water and 6.6 wt.% pyrolysis gas.…”

Abstract:In European Union 75% of used tires should be recycled. The most common method of used tires disposal, is burning in cement kilns, which does not solve the problem. Pyrolysis process can be an alternative way of utilization of tires. The aim of the researches was to check the influence of pyrolysis products (gas and oil fractions) on environment. Samples from pyrolysis process, like light oil fractions or pyrolysis gases were analyzed using gas chromatography. The pyrolysis installation should be hermetical, because of the PAHs which were detected in a light fraction of oil. In exhaust gases BTEX and PAHs were not detected.

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.
