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.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Diesel and gasoline prices drop in early 2020, but diesel drops substantially less

Green Car Congress

Although both diesel and gasoline are made from oil, the trends in their prices do not always go in parallel. While personal driving (which uses primarily gasoline) is down greatly because of various stay-at-home mandates, commercial truck transport (which uses primarily diesel) has been substantially less affected.

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. g CO 2 e/MJ for US conventional crude oil recovery. This range can be compared to ∼4.4
