Research Aiming Simultaneously Recycling Of Waste Polyolefins By Pyrolisis, In Order To Obtain Some Fuels For Compression Ignition Engines

摘要

This paper presents the undertaken research for the establishment of the compatibility of some polyolefin waste to be recycled by pyrolysis. Polyolefin are materials produced by a polymerization process of unsaturated aliphatic hydrocarbons and represents the most important group of plastic materials. It is important to mention that among polyolefin, polyethylene (PE) and polypropylene (PP) own the first places as quantity of produced waste. Due to the common origin of the two plastic materials (PE and PP) and the relatively close melting points, we chose them for the obtaining of some fuels which are compatible with compression ignition engines. Starting from 100% PE, the weight concentration of PP was increased up to 100%, the results of the undertaken experiments and measurements allowed us, in the final, to draw the chart of the variation of the yield of solid-liquid conversion as a function of weight concentration of the two chosen materials subjected to the process of recycling by pyrolysis.
