Extraction of Coal Liquefaction Residue with Aliphatic Hydrocarbon Solvents and the Separation and Characterization of Extracts by n-Heptane

open access: yesTaiyuan Ligong Daxue xuebao, 2022
The effects of four aliphatic hydrocarbon extractants (n-hexane, cyclohexane, petroleum ether, and n-heptane) on the extraction rate and properties of extracts from coal liquefaction residue were investigated by Soxhlet extraction experiments.

Effects of Diesel Hydrocarbon Components on Cetane Number and Engine Combustion and Emission Characteristics

open access: yesApplied Sciences, 2022
Commercial diesel consists of hundreds of hydrocarbons such as alkanes, cycloalkanes, and aromatics. The components of the fuel’s composition are what determine its physical and ignition properties, and their variations affect engine performance. In this

An Experimental Investigation of the Effects of Acetone, Tetrahydrofuran and N-heptane Fuel Blends on HCCI Combustion and Engine Performance

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2019
In the current study, a single cylinder, four stroke gasoline engine was converted to HCCI engine. HCCI engine was run at 1400 rpm, between λ=1.9 and λ=2.74 lambda values with n-heptane, acetone/n-heptane (A20N80) and tetrahydrofuran/n-heptane (F20N80 ...

Alternative fuels for spark-ignition engines: mixing rules for the laminar burning velocity of gasoline-alcohol blends [PDF]

open access: yes, 2012
Experimental measurements of the laminar burning velocity are mostly limited in pressure and temperature and can be compromised by the effects of flame stretch and instabilities.

Analysis of the effect of n-heptane and organic based manganese addition to biodiesel on engine performance and emission characteristics

open access: yesEnergy Reports, 2021
In this study, experiments were carried out in two stages. In the first stage, n-heptane (in 4, 8, 12, 16, and 20% volumes) was added to biodiesel (C0) which was produced from refined cottonseed oil via the transesterification method.
