Innovation in Pyrolysis Technology for Management of Scrap Tire: a Solution of Energyand Environment

Abstract

In this study a new approach in heating system for pyrolysis technology to the recovery of liquid hydrocarbons from solid tire wastes has been developed. A fixed-bed fire-tube heating pyrolysis reactor system has been designed and fabricated considering all of the process parameters. The solid tire wastes were pyrolysed in the reactor under N 2 atmosphere. The highest liquid product yield was obtained at a pyrolysis temperature of 475 o C for feed size of 4 cm 3 and vapor residence time of 5 sec. The tire pyrolysis liquids have been characterized including fuel properties, elemental analysis, FT-IR, 1 H-NMR, GC-MS analysis and distillation. The fuel properties of the pyrolytic liquids encourage their use as replacements for conventional liquid fuels. The analytical results of the 475 o C liquids showed that the tire-derived liquids are a complex mixture of C 5 -C 16 organic compounds, with a lot of high value light hydrocarbon limonene, single ring alkyl-aromatics and long-chain hydrocarbons. The present research result shows a better solution for energy and environment.

Pyrolysis characteristics of glass fiber-reinforced plastic (GFRP) under isothermal conditions

“…Fig. 1 presents experimental char and gas yield results from the literature, obtained from the various pyrolysis in diverse reactor configurations [9][10][11][12]. Among this data set, the range of gas and char yields was the smallest in a fixed bed reactor (FBR).…”

“…This implies that the time required for the oil shale reaction to reach the constant weight fraction would be the longest among this fuel, whereas, reaction time to achieve the same for RDF would be the shortest in this table. gas Ti re(FBR) [9] char Ti re( FBR) [9] gas PE(DTR) [11 ] char PE(DTR) [11] gas PP(FB) [10] char PP(F B) [ 10] gas P E(FB) [10] char P E(FB) [10] gas lignite(WMR) [1 2] char lignit e(WMR) [12 ] Another factor which is important for explaining the conversions of organic materials during pyrolysis is the mass balance.

Modeling of destruction processes during recycling of rubber-technical waste using the technology of multi-contour circulation pyrolysis

“…Results of the study showed that heat-generating capacity of the resulting liquid fuel is 40.4 MJ/kg. The paper does not provide other characteristics compared to traditional diesel fuel, which does not allow us to talk about the high potential of fuel replacement.In the study [4], a new approach to a heating system with the use of liquid products of pyrolysis of waste tires was presented. Fuel properties of pyrolysis liquids, such as density, viscosity, the content of carbon and hydrogen, are almost comparable with commercial automobile diesel fuels.…”
