Boiling point of hydrogen gas
Large quantities of H2 are used in the "upgrading" of fossil fuels. Key consumers of H2 include hydrodealkylation, hydrodesulfurization, and hydrocracking. Many of these reactions can be classified as hydrogenolysis, i.e., the cleavage of bonds to carbon. Illustrative is the separation of sulfur from liquid fossil fuels: R2S + 2 H2 → H2S + 2 RH WebApr 13, 2024 · Alcohol, or ethyl alcohol (ethanol), is a chemical compound that can be found in alcoholic beverages. It's composed of carbon, hydrogen, and oxygen atoms and has the molecular formula C2H5OH. Alcohol is produced by the fermentation of sugars, starches, and other carbohydrates by yeast. There are many types of alcohols depending on the …
