Fatty acid esters can improve cetane number of diesel from direct coal liquefaction

Green Car Congress

Researchers from the Shanghai Institute of Technology report that fatty acid esters can be used as cetane improvers for diesel fuel produced via direct coal liquefaction (DCL). Compared to petrodiesel, diesel from direct coal liquefaction (DDCL) contains almost no sulfur. A paper on theier work is published in the journal Fuel.

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. CO 2 emissions decreased 2.2% from 2018 to 2019.
