Pyrolysis Oil Derived from Plastic Bottle Caps: Characterization of Combustion and Emissions in a Diesel Engine

Recycling used plastic can help reduce the amount of waste generated. Existing methods, namely process pyrolysis, are chemical heating processes that decompose plastics in absence oxygen. This decomposes a controlled environment order to produce fuel from waste. The present study consequently investigated physical and properties pyrolysis oil derived bottle caps (WPBCO) effects on engine performance emission characteristics diesel operating WPBCO. experiments were conducted with single-cylinder at constant 1500 rpm under various loading conditions. experimental results test fuels indicated WPBCO have similar functional groups components. In comparison, has lower kinematic viscosity, density, specific gravity, flash point, fire cetane index, distillation behavior than fuel. However, high gross calorific value, which makes it suitable replacement for fossil comparison fuel, use engines increased brake-specific consumption (BSFC) brake thermal efficiency (BTE) all load combustion indicate resulted decreased in-cylinder pressure (ICP), rate heat release (RoHR), stability compared addition, advances start more strongly emissions NOX, CO, HC, smoke. particulate matter (PM) analysis showed generated higher PM concentration When was combusted, maximum soot oxidation required temperature, meaning oxidizing took less energy easier break down soot.
