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.

New study suggests reported PAH emissions in oil sands region greatly underestimated

Green Car Congress

Results from a new modeling assessment of contamination in the Athabasca Oil Sands Region (AOSR) suggest that officially reported emissions of polycyclic aromatic hydrocarbons (PAHs) in that region have been greatly underestimated. Accounting for evaporative emissions (e.g., —Parajulee and Wania. Source: Parajulee and Wania.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. This is not the same as crude oil occurring naturally in shales, as in the Bakken.
