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.

ORNL team develops carbon-nanotube-based superlubricity coating

Green Car Congress

In comparison, when dry metals slide past each other, the coefficient of friction is around 0.5. With an oil lubricant, the coefficient of friction falls to about 0.1. We tried it without oil; it didn’t work. The reason is, without oil, friction removes the carbon nanotubes too aggressively. 2022.100297.

Goodyear unveils 90% sustainable-material demonstration tire, approved for road use

Green Car Congress

A sustainable material is defined as a bio-based/renewable, recycled material or one that may be produced using or contributing to other sustainable practices for resource conservation and/or emissions reductions including mass-balance materials. Today, eight product lines, and some racing tires, include soybean oil.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.

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

Green Car Congress

Perhaps surprisingly, the greenhouse gas footprint of blue hydrogen is more than 20% greater than burning natural gas or coal for heat and some 60% greater than burning diesel oil for heat, again with our default assumptions. Our analysis assumes that captured carbon dioxide can be stored indefinitely, an optimistic and unproven assumption.

Meanwhile, wet waste feedstocks, such as animal manure and fats, oils, and greases (FOG), represent another important category of resources that could be utilized to produce MCCI bioblendstocks due to its abundant availability.

Studies find oil sands-derived crude oil no more corrosive in pipelines than other crudes

Green Car Congress

Both scientific research and industrial experience have found that bitumen-derived crude oil (i.e., crude from the oil sands) is no more corrosive in transmission pipelines than other crudes, according to Natural Resources Canada (NRC). In the absence of water, the crude oil is noncorrosive. —ASTM G205.
