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 global oil demand likely to grow despite pandemic, climate policies

Green Car Congress

The COVID-19 pandemic has significantly affected both consumer and commercial transportation, but global oil demand will probably continue to grow through 2030, according to a new study. In three of the four scenarios, global oil demand continued to grow through 2030. Lines represent global oil demand by study scenario.

Production of crude oil as a percentage of proved reserves: Recent worldwide and US trends

Green Car Congress

In this analysis, I examined the relation between crude-oil production and crude-oil reserves in the world overall and in the United States alone. The variable of interest was the amount of crude oil produced as a percentage of proved reserves of crude oil. For the world, production of crude oil in 1980 represented 3.4%

UCalgary, Rice team uses flash joule heating to manufacture graphene from petroleum waste

Green Car Congress

A team from the University of Calgary and Rice University has used flash joule heating (FJH) ( earlier post ) to convert low-value asphaltenes—a by-product of crude oil refining—into a high-value carbon allotrope, asphaltene-derived flash graphene (AFG). Flash graphene from asphaltenes. (A)

China researchers hydrotreat waste engine oil and scrap tire oil blend to produce diesel- and jet-range fuel

Green Car Congress

Researchers at Henan Polytechnic University in China have hydrotreated the oil derived from hydrothermal liquefaction of scrap tires (STO) with waste engine oil (WEO) using five different activated carbon-supported noble metal catalysts—Pd/C, Pt/C, Ru/C, Ir/C, and Rh/C—for the production of liquid fuels.
