Chang’an study examines benefits of CTL F-T diesel blends on combustion and emissions

Green Car Congress

Researchers at Chang’an University in China investigated the effect of blends of Fischer-Tropsch (F-T) diesel fuel from indirect coal-to-liquid (CTL) and petroleum diesel fuel on combustion and emission characteristics under various injection timing (IT) and engine loads. A report on their work is published in the journal Fuel.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust.

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. 2015.02.068.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Carbon dioxide emissions, including emissions from developing, processing, and transporting the fuels, are shown in orange.

CSIRO and partners to test Direct Injection Carbon Engine to reduce brown coal emissions by up to 50%

Green Car Congress

DICE involves converting coal or biomass into a water-based slurry (called micronised refined carbon, MRC) that is directly injected into a large, specially adapted diesel engine. The project is supported by industry partners including Exergen, Ignite Energy Resources, AGL, MAN Diesel & Turbo and EnergyAustralia.

Linc Energy signs MoU with UK Coal for underground coal gasification collaboration in UK

Green Car Congress

has signed a Memorandum of Understanding (MOU) with UK Coal Mining Ltd., one of the largest land holders and biggest coal producers in the UK. These sites relate to certain areas of coal within the Warwickshire, Yorkshire and Leicestershire Coalfields surface and underground mine infrastructure and sub-station assets owned by UK Coal.
