Renewable diesel fuel and FT-fuel as alternative to diesel fuel

open access: yesThe Journal of Zhytomyr State Technological University. Series: Engineering, 2019
Найбільш розповсюдженим дизельним альтернативним паливом є дизельне біопаливо (біодизель). Велика в’язкість біодизельного палива та збільшення викидів оксидів азоту, порівняно з дизельним паливом, обмежують використання його в двигунах автомобіля. До багатообіцяючої перспективи належать відновлювальне дизельне та синтетичне паливо.
