摘要

在全球范围内,由于车辆数量的增加,废旧轮胎正在增加。相反,近年来,为了克服化石燃料危机,人们正在探索化石燃料的替代品。本研究以自行车和三轮车轮胎废弃物为研究对象,研究了温度、进料粒度、表观气相停留时间等参数对热解产物收率的影响。采用固定床电加热反应器,在400 ~ 550℃的温度下进行热解,保持不同粒径,升温速率恒定在20℃/min。轮胎热解油(TPO)的最佳产率为42 wt.%,温度为500℃,样品体积为4.0 cm3。测定了TPO的燃料性能(如密度、粘度、热值、闪点、倾点、硫含量、灰分等)、官能团研究,并与常规燃料和国际标准进行了比较。TPO的理化性质确定了TPO作为炉油在各种工业过程中的应用。生物油的分馏得到各种附加值产品,包括生物汽油、生物煤油和其他化学品。废轮胎处理的热解和后续技术的商业实施将使孟加拉国的废轮胎有活力地增值。达卡大学学报(自然科学版),70(2):29- 34,2022 (7)

Production, Characterization and Evaluation of Pyrolysis Oil from Tyre Wastes Available in Bangladesh
Globally, scrap tyres are increasing due to the increased number of vehicles. In contrast, in the recent years, alternatives to fossil fuels are exploring to overcome the fossil fuel crisis. In this study, pyrolysis of bicycle and rickshaw tyres wastes was conducted and parametric effects (e.g., the effect of temperature, feed size and apparent vapor residence time etc.) on the pyrolysis product yields were determined. A fixed bed electric heating reactor was used for pyrolysis at 400 - 550 oC, maintaining various particles sizes and a constant heating rate of 20oC/min. The optimum Tyre Pyrolysis Oil (TPO) yield of 42 wt.% was obtained at 500 oC for a sample size of 4.0 cm3. The fuel properties (e.g., density, viscosity, calorific value, flash point, pour point, sulphur content, ash content etc.), functional group studies of the TPO were determined and was compared with the conventional fuel and with international standards. The physico-chemical properties of TPO confirm the use of TPO as furnace oil in various industrial processes. The fractionation of bio-oil gives various value added products including bio-gasoline, bio-kerosene and others chemicals. The commercial implementation of the pyrolysis and follow-up technologies for waste tires processing will allow energetic valorization of waste tyres in Bangladesh. Dhaka Univ. J.
