摘要

Abstract

Drying pretreatment is a widely adopted preprocessing method prior to the pyrolysis of oily sludge(OS). In this study

a tube furnace

thermogravimetric—infrared spectroscopy (TG-IR)

and gas chromatography—mass spectrometry (GC-MS)

were employed to evaluate and compare the pyrolysis behaviors of original and dried OS

and to analyze product distributions under various conditions. The results indicate that both original and dried OS undergo pyrolysis in five distinct stages

among which stages 2

and 4 are the most significant. Kinetic analysis reveals that dried OS exhibits lower activation energies of 56.032

152.166

and 211.462 kJ·mol

- 1

for these three stages

corresponding to reaction mechanisms of D6 (3D diffusion)

F4 (chemical reaction) and F4

respectively. In contrast

original OS exhibits higher activation energies of81.481

235.933

and214.194kJ·mol

- 1

associated with the mechanisms A8(random nucleation and growth)

and F1 (order of reaction)

respectively. TG-IR analysis identifies H

and CH

as the primary gaseous products from dried OS

with the optimal methane-rich gas yield achieved at temperatures below 724.61 ◦C. Furthermore

GC-MS analysis of the pyrolysis oil obtained from dried OS at 600 ◦C reveals higher concentrations of hydrocarbons and oxygenated compounds

along with reduced levels of nitrogen-containing and hazardous constituents

suggesting its superior suitability and cost-effectiveness as a recyclable fuel.
