چکیده مقاله:
In this study, re-refining of used insulating oil by mesoporous silicate
material (MCM-۴۱) and metallic sodium was investigated. Also, the
effect of silicate absorbents which was synthesized and functionalized
with aluminum (Al-MCM-۴۱) was studied (۱۸ wt% and ۳۶ wt%). The
physical and structural properties of Al-MCM-۴۱ were characterized by
FT-IR, BET, XRD, FESEM and the obtained results illustrated a successful
synthesis of the mesoporous material. The refined oil was treated by MCM-
۴۱ adsorbent. After that, total acid number (TAN) of used insulating oil
was effectively reduced by metallic sodium. The effect of some parameters
such as contact time, temperature and the dosage (sodium and adsorbent
to oil ratio) was designed and optimized by response surface method
(RSM). The results showed that the acid number incredibly decreased
at ۱۵۰, ۶۰ min and ۲% of sodium to oil. The color of the re-refined oil
was significantly reduced. The factors such as, time, temperature and
dosage was statistically studied by ANOVA. The adsorption of MCM-۴۱
was also studied by this way. Based on proposed procedure, the modeling
was carried out. Treating of oil with MCM-۴۱ after using metallic sodium
causes lower color of oil.
