Abstract
Przedmiotem wynalazku jest wyznaczanie stopnia starzenia benzyn, charakteryzujący się tym, że obejmuje następujące etapy: a)pobranie próbki badanej benzyny w wybranych punktach czasowych, korzystnie od 0 do 24 godzin, po czym b) dokonanie na otrzymanych próbkach pomiarów techniką elektrochemicznej spektroskopii impedancyjnej, przy częstotliwości z zakresu 1 mHz - 30 MHz, z uzyskaniem w wyniku widm impedancyjnych w postaci wykresu Nyquista tj. zależności wartości urojonej składowej impedancji Zim i wartości rzeczywistej składowej impedancji Zre, w funkcji częstotliwości zmiany potencjału w zakresie od 10 do 10V dla tej benzyny w czasie 0 i kolejnych punktach czasowych, c)poddanie analizie wyników pomiaru z etapu b) i dopasowanie ich do eksperymentalnych wyników widm z wyznaczeniem wartości następujących parametrów starzeniowych jak: oporność R, czas relaksacji, ? i pojemność C w badanej próbce benzyny. Przedmiotem wynalazku jest również zastosowanie wyznaczonych parametrów stopnia starzenia benzyn do oceny jakości benzyn.The subject of the invention is the determination of the gasoline aging degree, characterized in that it comprises the following stages: a) taking a sample of the tested gasoline at selected time points, preferably from 0 to 24 hours, then b) making measurements on the obtained samples by electrochemical impedance spectroscopy, using frequencies in the 1 mHz - 30 MHz range, resulting in the result of impedance spectra in the form of a Nyquist chart, i.e. the relationship between the imaginary value of the impedance component Zim and the actual value of the impedance component Zre, as a function of the frequency of potential change in the range of 10 to 10V for this gasoline over time 0 and subsequent time points, c) subjecting the analysis of the measurement results from stage b) and adapting them to the experimental results of spectra with determination of the values of the following aging parameters as: resistance R, relaxation time,? and capacity C in the gasoline sample tested. The invention also relates to the use of determined petrol aging parameters for the assessment of gasoline quality.
