Environmental assessment of the exploitation of diesel engines powered by biofuels

Grzelak Paulina Luiza, Żółtowski Andrzej

Combustion Engines

2020

R. 59, nr 1

31--35

Many factors, such as climate change and the associated risk of increasing the average temperature on the globe, energy security and the finishing of fossil fuel deposits have caused other renewable energy sources to be sought. Transport, as a branch of industry largely responsible for air pollution and greenhouse gas emissions in large cities, requires the necessary changes in the way vehicles are powered. Until now, the fuels available at petrol stations use admixtures of first generation biofuels, such as bioethanol, as a 5% additive to motor gasolines and biodiesel (FAME) as a 7% additive to diesel oil. The article presents the idea of biorefinery installations, specifies the spectrum of substrates of the second and advanced generations, which may be a biorefinery input, including waste oils that can be used to produce hydrogenated HVO vegetable oils and other high-value products. The paper presents he existing biorefinery plant in Venice resulting from the transformation of a conventional oil refinery in which HVO fuel is produced. The article also presents the parameters of this new biofuel and compared them with the parameters of other fuels used to power self-ignition engines, such as FAME and diesel, along with discussing the prospects for HVO fuel development in Europe.

DMF jako biopaliwo drugiej generacji

Grzelak Paulina Luiza

Przegląd Techniczny : Gazeta Inżynierska

2019

nr 9-10

24--28

W artykule zaprezentowano ocenę DMF jako perspektywicznego biopaliwa drugiej generacji. Przedstawiono jego podstawowe właściwości chemiczne na tle komercyjnego biopaliwa, jakim jest bioetanol. Zaprezentowano również możliwości surowcowe do wytwarzania tego paliwa. Przeanalizowano możliwości zastosowania DMF we współczesnych silnikach spalinowych wraz z odwołaniem się do istniejących badań emisyjnych. Zwrócono także szczególną uwagę na wpływ na środowisko wynikający z zastosowania DMF jako biopaliwa lub biokomponentu silnikowego.

The paper presents the DMF assessment as a prospective secondo generation biofuel. It presents its basic chemical properties in comarison to bioethanol. Raw material capabilities for DMF production were also presented. There were analyzed the possibilities of using DMF as a fuel for internal combustion engines. Attention was also paid to the impast of DMF on the environment as a result of DMF application as a biofuel or biocomponent.
