dc.description.abstract | In this research work, the effect of different concentrations of copper, iron, lead, zinc and nickel ions on the tendency for gum formation in
gasohol fuel is investigated. For that purpose, a gasohol sample has been doped with these five metals ions at concentration levels of 0.25, 1.0, 2.0
and 3.0 μg ml−1. Washed gum content tests have been carried out using ASTM D 381 on samples stored for 7, 14, and 28 days. The results show
that gum formation is strongly affected by Cu and Fe, with a much weaker effect from Ni and Zn, and an almost negligible effect from Pb. A
variance analysis (ANOVA) of the experimental results shows that an increase in metal concentration strongly increases the rate of gum formation
for all metal ions investigated, particularly Cu and Fe, while an increase in storage time has only a much weaker effect, being negligible for Zn. | pt_BR |
