Improvement of Waste Tire Pyrolysis Oil and Performance Test with Diesel in CI Engine

Abstract

The standard of living, quality of life, and development of a nation depend on its per capita energy consumption. Global energy supply that mainly depends on fossil fuel is decreasing day by day. It is estimated that the energy demand will be increased five times by the year 2021 from present scenario. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Pyrolysis is one of the promising alternative fuel technologies which produces valuable oil, char, and gas product from organic waste. Early investigations report that tire pyrolysis oil extracted from vacuum pyrolysis method seemed to have properties similar to diesel fuel. The main concern of this paper is to produce and improve the properties of crude tire pyrolysis oil by desulfurizing, distilling, and utilizing it with diesel in CI engine to analyze the efficiency for various compositions.

Current Status and Potential of Tire Pyrolysis Oil Production as an Alternative Fuel in Developing Countries

“…To overcome these problems, sustainable, secure, and pollution-free energy sources must be used at the same time which could combine social and economic development with environmental protection [15][16][17]. Tire pyrolysis oil (TPO) is among the effective substitute fuel technologies, and it is used to produced useful products of tire pyrolysis oil, char, and pyro gas [18]. Tire pyrolysis oil, derived from waste automotive tires, was tested and compared with petroleum products and it could also be used in the compression-ignition engine [19].…”

“…After that, two layers named thin and thick layers are found in the mixture, the thick layer is discarded as sludge while the thin layer is collected for vacuum distillation. Around 61.6% of sulfur gets removed from this process [18]. Then, some remaining particles in the TPO get removed by the filtration method by using a fabric filter; the efficiency of the filtration method is about 99% [61].…”

“…It is currently estimated that approximately 4 billion waste tires are in stock and landfills, worldwide [22]. One billion waste tires can generate 5.26 million tons of tire pyrolysis oil [18].…”

Studies on Improvement of Performance of Compression Ignition Engine Fuelled with Mixture of Honge Biodiesel and Tire Pyrolysis Oil

“…They observed that the brake specific fuel consumption of DTPO 25 blend is very close to the specific fuel consumption of diesel. They concluded that the DTPO 25 blend can be directly utilized in diesel engine without any engine modification [13].…”

Waste tires pyrolysis oil as a source of energy: Methods for refining

“…In the review paper of Ahmad and Ahmad, 70 it was noted that large number of researchers use acids, mainly H 2 SO 4 , as a way to reduce the sulfur content of pyrolysis oils. Researchers from Bangladesh—Islam and Nahian 71 —apply a methodology in which the process passes through three stages: drying, treating with H 2 SO 4 and distillation. The sulfur is reduced from 1.12 to 0.43 mass%.…”
