Sentences with phrase «as hydrogenation»

Not exact matches

Palm oil traditionally has been used for baking, shortenings, margarines and deep fat frying, as it is shelf stable with a high melting point and does NOT require hydrogenation.

The ORNL - led study instead provides evidence for the second mechanism, in which one H atom associates with an O atom to make OH and the other H associates with cerium (Ce) to make CeH — a hydride that may serve as a source of H for industrially important hydrogenation reactions.

The hydrogenation catalysts mostly used today contain toxic or expensive heavy metals, such as nickel, palladium or platinum.

Supercritical carbon dioxide is also an excellent medium for its own fixation, as demonstrated by studies of its hydrogenation.

To study how and why DEB changes in volatility, the researchers measured properties such as vapor pressures and melting points, probed molecular structure, and ran quantum mechanical computer simulations to model the hydrogenation process.

Together we embarked on a new direction involving single atom alloys as catalysts for selective hydrogenation reactions.

For CO2 hydrogenation purposes, most known catalysts are based on precious metals such as iridium, rhodium or ruthenium.

Manganese is the third most abundant metal in Earth's crust after titanium and iron, and presents much lower toxicity as compared to many other metals used in CO2 hydrogenation.

For instance, carbon dioxide enables energy storage by reacting with hydrogen gas — called the hydrogenation process — transforming the mixture into higher energy liquid compounds such as methanol that can be easily transported and used as fuel for cars.

Hydrogenation of graphene opens a bandgap in graphene, so that it might serve as a semiconductor component in new devices.

This study focuses on the effect of different parameters such as the use of additives as well as the effect of milling time on the material hydrogenation / de-hydrogenation performances.

The fatty acids known as trans fats are made through a chemical process called hydrogenation which solidifies their oils to ensure a longer shelf - life in the grocery store.

-LSB-...] this method often leads to hydrogenation or partial hydrogenation of the oil and the presence of trans - fatty acids, as well as the removal of beneficial fatty -LSB-...]

Consumers will obtain isomerized essential fatty acids from vegetable oils currently marketed in the U. S... A large portion of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent (9).

Our bodies basically don't know how to handle trans - fats as they are not truly found in nature; they are manufactured in a factory with a process called hydrogenation, where an extra hydrogen bond is forced into the fat molecule.

http://www.tfx.org.uk/page62.html ``... Most importantly, however, the naturally occurring trans fats have not, as they occur in animal fats, been shown to share the harmful properties of the synthetic trans fat resulting from hydrogenation.

My understanding is that transfats are created as an unintended side reaction to the catalytic hydrogenation of PUFA's only.

A large portion of canola oil used in processed food has been hardened through the hydrogenation process, which introduces levels of trans fatty acids into the final product as high as 40 percent.25 In fact, canola oil hydrogenates beautifully, better than corn oil or soybean oil, because modern hydrogenation methods hydrogenate omega - 3 fatty acids preferentially and canola oil is very high in omega - 3s.

Fatty acids containing carbon - carbon double bonds (monounsaturated, such as the main ones in olive oil, or polyunsaturated) do produce small quantities of trans fatty acids when heated strongly, but it's in very small amounts (here, here, here, here) The process that really increases the trans fatty acid concentration is partial hydrogenation, an industrial process that's used to raise the melting temperature of polyunsaturated oils.

Artificial trans fatty acids are produced by adding hydrogen — a process known as partial hydrogenation — to liquid oils; this makes them solid at room temperature, more stable during repeated deep - frying and extends their shelf time [19].

Besides the possibility of our applying a similar process to the bituminous coal and tars made therefrom, in this country, the research on hydrogenation has been extended by one of the great oil companies of the United States which at great expense has learned how the method can be so modified as to apply to petroleum hydrocarbons.
