Review of co-processing of biocrudes in oil refineries

Green Car Congress

Liquid intermediates from pyrolysis and hydrothermal liquefaction (HTL) can be co-processed in an oil refinery along with conventional crude oil. After pyrolysis, the vapors are condensed to give a dark brown fast pyrolysis bio-oil (FPBO). In fast pyrolysis, biomass is quickly heated to around 500 °C in the absence of oxygen.

VTT study concludes gasification-based pathways can deliver low-carbon fuels from biomass for about 1.90-2.65 US$/gallon

Green Car Congress

The horizontal red lines show the comparable price of gasoline (before tax, refining margin 0.3 $/gal, exchange rate: 1 € = 1.326 $) with crude oil prices 100 $/bbl and 150 $/bbl. The costs ranged from 58–65 €/MWh for methanol; 58–66 €/MWh for DME; 64–75 €/MWh for Fischer-Tropsch liquids; and 68–78 €/MWh for synthetic gasoline.

IFQC annual ranking of gasoline sulfur standards sees progress around the world; US drops to 46th

Green Car Congress

Maximum gasoline sulfur limits. A trio of European countries and one from South America made major strides in reducing their levels of sulfur content in gasoline, allowing them to advance in the annual global ranking published by Hart Energy’s International Fuel Quality Center (IFQC). Sulfur is found naturally in crude oil.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

The study by researchers in Finland and Greece, published in the ACS journal Environmental Science & Technology , suggests that both the characteristics of these particles and the mechanism by which they form seem to differ significantly from those of soot and nucleation particles. changing driving conditions also affect particle emissions.
