Recycling of waste tires for bio crude fuel production through a pyrolysis system

الملخص EN

Recycling of solid waste is one of the most valuable method which is used in worldwide for integral solid waste management.

Waste tires are considered to be a source of energy and valuable chemical products.

In this study waste tire samples of mixed types (passenger, truck, and heavy vehicles etc.

) were decomposed thermally in a fixed bed reactor made up of stainless steel placed inside an electrical heater.

Thermal pyrolysis on tire waste samples with (1-2) cm of particle size was carried out at temperatures of 330 ᵒC, 430ᵒC, 530ᵒC, and 630 ᵒC under Argon flow rate of 0.5 L/min and retention time of 15 min to study the effect of temperature on the distribution of pyrolysis products yield.

Three main products were obtained by tire pyrolysis pyro oil, gas, and solid residue.

Chemical compositions of pyrolysis oil product were characterized by Gas chromatography mass and Fourier transform infrared spectroscopy analyses, it is a complex mixture of alkane, alkene, cycloalkane, cycloalkane, alcohol, ester, and aromatic compounds which are preferable in fuel.

If found that a limonene compound occupies the largest proportion of the oil product which is considered as a more valuable compounds.
