Testing of mixed corrosion inhibitors for steels in the presence of ethanol-gasoline blended fuels

Popis výsledku v původním jazyce

Bioethanol produced from biomass is the most suitable alternative to petrol that is used worldwide. The addition of ethanol to gasoline greatly changes the physicochemical properties of the fuel. If the low-ethanol fuel mixture is contaminated with water, the water can be divided into hydrocarbons and water-ethanol phases, which can be highly corrosive. The aim of the work was to test corrosion protection by two mixed corrosion inhibitors containing propargyl alcohol, dibenzyl sulphoxide, mercaptobenzothiazole and octadecylamine. The effectiveness of corrosion inhibitors was tested in ethanol/gas mixtures (E10, E25, E60 and E85) contaminated with traces of sulphates, chlorides, acetic acid and sulphuric acid. Corrosion properties were tested on carbon steel 11 in static and dynamic test in the fuel system. Traceable qualitative fuel properties included, in particular, TAN (total acid number), PV (peroxide value) and density. The highest aggressiveness for steel was demonstrated in the contaminated E60 fuel without inhibitor. In the presence of the same fuel, the highest efficacy (at least 75%) was measured for the octadecylamine inhibitor.
