An experimental study on usage of plastic oil and B20 algae biodiesel blend as substitute fuel to diesel engine

Abstract

Usage of plastics has been ever increasing and now poses a tremendous threat to the environment. Millions of tons of plastics are produced annually worldwide, and the waste products have become a common feature at overflowing bins and landfills. The process of converting waste plastic into value-added fuels finds a feasible solution for recycling of plastics. Thus, two universal problems such as problems of waste plastic management and problems of fuel shortage are being tackled simultaneously. Converting waste plastics into fuel holds great promise for both the environmental and economic scenarios. In order to carry out the study on plastic wastes, the pyrolysis process was used. Pyrolysis runs without oxygen and in high temperature of about 250-300 °C. The fuel obtained from plastics is blended with B20 algae oil, which is a biodiesel obtained from microalgae. For conducting the various experiments, a 10-HP single-cylinder four-stroke direct-injection water-cooled diesel engine is employed. The engine is made to run at 1500 rpm and the load is varied gradually from 0 to 100 %. The performance, emission and combustion characteristics are observed. The BTE was observed to be higher with respect to diesel for plastic-biodiesel blend and biodiesel blend by 15.7 and 12.9 %, respectively, at full load. For plastic-biodiesel blend, the emission of UBHC and CO decreases with a slight increase in NO x as compared to diesel. It reveals that fuel properties are comparable with petroleum products. Also, the process of converting plastic waste to fuel has now turned the problems into an opportunity to make wealth from waste.

A review on conversion techniques of liquid fuel from waste plastic materials

“…CO 2 and unburned hydrocarbon were found higher with usage of plastic fuel. Smoke quantity was also increased with WPO .…”

The Experimental Features of a Compression Ignition Engine Running On Pure Diesel and Mixtures of Diesel and Manilkara Zapota Methyl Ester

“…Transesterification is an organic procedure of altering bid branched triglyceride molecules of plant fats and oils into minor molecules of straight chain, just like the size of diesel fuel molecules. This method takes place due to the reaction between alcohol (Methanol-CH 3 OH) and vegetable oil under the impact of the catalyst (NaOH or KOH) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

“…The earlier work of numerous academics [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] has described that, the biodiesel blend with predictable diesel has significantly decrease the deplete emissions and rises the performance of engine. The biodiesels obtained till now are not sufficient to encounter the worldwide requirement of fuel therefore exploring other possible sources as an auxiliary for conservative fuels is a requirement.…”

A Study on Property Variations of Biodiesels derived from Indian Origin based Non-Edible Oils by Blending them with Plastic Pyrolysis Oil

“…The reports show that the engine performance can be improved by blending waste plastic oil to heavy oil used in marine applications [Ioannis S. A and P Tserkezou 2008]. Experiments on plastic oil and B20 algae blend were conducted by Ramesh et al It was observed by the authors that the brake thermal efficiency of B20 was 15.7% higher than that of conventional diesel fuel [Ramesh et al 2016]. Therefore, the literature strongly supports the functional suitability of plastic pyrolysis oil in a compression ignition engine and, if properly understood, it can substitute diesel in near future.…”
