Sentences with phrase «hydrogen content»

The hydroprocessing increases the intrinsic hydrogen content of the pyrolysis oil, producing polyols and alcohols.

«Anything with high hydrogen content, including water, would work well.»

Two billion year - old water pockets and a revised deep hydrogen content are good news for Earth's vast subsurface biosphere, and could offer clues to life on Mars and much further beyond.

The team of astronomers who discovered it — led by Robert Quimby of the California Institute of Technology (Caltech) in Pasadena — tentatively have labeled the 4.7 billion light - years away ex-star a Type II - L supernova because of its brightness and because its light spectrum shows a primarily hydrogen content.

The high carbon dioxide emission factor for anthracite reflects the coal's relatively small hydrogen content, which lowers its heating value.

11For the coal analyzed in the EIA Coal Analysis File, the average hydrogen content was as follows, by weight (dry basis): anthracite, 2.5 percent; bituminous coal, 5.0 percent; subbituminous coal, 4.8 percent; and lignite, 4.4 percent.

According to a 2006 report from the U.S. Department of Energy, amine - borane complexes have great potential as a component in fuel sources due to their high hydrogen content.

The team collected feathers from nearly 700 birds and analyzed their carbon and hydrogen content.

The Dutch team postulates in Nature that an older massive star collided with a younger, smaller, hydrogen - rich star, which boosted its hydrogen content.

Amylose effect on colonic activity assessed by measuring the hydrogen content of breath: ars.usda.gov/research/publications/publications.htm?

Possibilities include (but are not limited to) novel gasifiers, new applications for commercial gasifiers, co-gasification approaches, new technologies to increase the hydrogen content of commercially available syngas, and technologies to separate CO and H2.

The hydrogen content of typical raw syngas is roughly equivalent to the CO content, whereas most liquids and chemical production require at least a 2:1 ratio and high carbon capture IGCC configurations to make power require an even higher hydrogen content gas feed to the turbine.

(4) Consequently, variations in the ratios of carbon to heat content of coal are due primarily to variations in the hydrogen content.

Conversely, coal is 40 to 85 % carbon by weight, and much of the hydrogen content in coal is from moisture.
