Abstract

The main objective of this publication is to
handle the recycling of used motor oil, introducing optimal methods of
processing acid activated bentonite compared with natural bentonite.
Comparative results of chemical analysis of the oil samples analyzed after
treatment with these absorbent enabled significant estimates issued on changes specific
parameters before and after treatment of the oil. This process consists in
removing unwanted components of the oil through the bentonite adsorptive
properties of the Republic of Kosovo. And at the same time related to generated
oil production, based on a practice ecologically safe, therefore renewed oils
or recycled may turn into products, to be reused as base oils or as fuel in the
engines of cars or industrial machinery. Results showed that bentonite activation
increases specific surface and the cumulative volume, at the same time with increasing
the concentration of sulphuric acid. This shows that with increasing
concentration up to 30% do not have limits or the optimal amount of acid
concentration that takes to obtain as large as possible specific surface area.
For extended time of activation to these parameters grow in activated acid
samples of 10% and 20% while the acid activated samples of concentration 30%
their values are decreased. Also it turns out that oil is not damaged or
altered, but rather their effect is best shown regenerative abilities. This
method has shown that the basic components of motor oil are maintained and their
consistency is not damaged.
