Feasibility of Waste Engine Oil Electrooxidation with Ni-Co and Cu-B Catalysts
2022
To implement a circular economy policy, methods of using waste products as a starting point for other technologies are constantly researched. One of the waste products that should be disposed of after use is waste engine oil (WEO). Despite the permanent introduction of the electrification of cars, the number of combustion vehicles (and, thus, the production of WEO) is constantly increasing. For these reasons, the reuse of WEOs is extremely important; e.g., to use these oils for energy purposes. One of the potential uses of this type of oil is as fuel for fuel cells (for direct electricity production). To lower the production costs of electrodes for fuel cells, catalysts that do not contain …
Electrooxidation of methyl alcohol with Ni-Co catalyst
2018
Due to development of the renewable energy sources, the powering of fuel cells (FCs) with bio-fuels is very important. The one of this fuel is methyl alcohol. The use of fuel cells on a large scale is mainly limited by the high cost of catalysts – mainly platinum. Elimination of Pt as catalyst would allow for wider commercial application of FCs. The paper presents a study of methyl alcohol electrooxidation on electrode with NiCo alloy catalyst. Researches were done by the method of polarizing curves of electrooxidation of methanol in glass vessel. Conducted measurements show that there is a possibility of electrooxidation of methanol with Ni-Co catalyst. In any case, the process of electroo…
MICROBIAL FUEL CELL WITH Ni-Co CATHODE AND KMnO4 CATHOLYTE
2017
The improving standard of living causes the increases in energy consumption and waste or wastewater production. The possibility of combining wastewater treatment and electricity production can be accomplished by means of a microbial fuel cell. The possibility of wastewater treatment using the Ni-Co alloy as cathode catalyst with KMnO4 catholyte for microbial fuel cells was presented in this paper. The measurements covered the comparison of changes in the concentration of COD, NH4+ and NO3- in the reactor without aeration, with aeration and using a microbial fuel cell (with Ni-Co cathode and KMnO4 catholyte). The reduction time for COD using a microbial fuel cell with the Ni-Co catalyst (and…
Mikrobiologiczne ogniwo paliwowe z katodą Ni-Co i katolitem kMnO4
2017
Wzrost poziomu życia powoduje wzrost zużycia energii oraz ilości generowanych odpadów i ścieków. Możliwość jednoczesnego oczyszczania ścieków i produkcji energii elektrycznej zapewniają mikrobiologiczne ogniwa paliwowe. Praca przedstawia możliwość oczyszczania ścieków w mikrobiologicznym ogniwie paliwowym z katodą Ni-Co i katolitem KMnO4. Pomiary obejmowały zmiany stężeń ChZT, NH 4+ oraz NO3- w reaktorze bez napowietrzania,z apowietrzaniem oraz przy wykorzystaniu mikrobiologicznego ogniwa paliwowego z katodą Ni-Co i katolitem KMnO4. Czas redukcji ChZT podczas napowietrzania i wykorzystania mikrobiologicznego ogniwa paliwowego jest porównywalny. Wykazano zatem możliwość wykorzystania katody …
