Hydrogen fuel enhancement from electrolysis (using automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, [14] [15] [16] although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy). Proponents, who sell the ...
Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. [2] Sulfonated lignin (SL) refers to other forms of lignin by-product, such as those derived from the much more popular Kraft process , that have been processed to add sulfonic acid groups.
Alset GmbH developed a hybrid hydrogen systems that allows vehicle to use petrol and hydrogen fuels individually or at the same time with an internal combustion engine. This technology was used with Aston Martin Rapide S during the 24 Hours Nürburgring race. [11] The Rapide S was the first vehicle to finish the race with hydrogen technology. [12]
The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body. They are also used as regulated food additives. [2] When in food or drink, sulfites are often lumped together with sulfur dioxide. [3]
Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.

Holley Brothers Company advertisement for carburetors in the Automobile Trade Journal, 1916.. Holley's history starts in Bradford, Pennsylvania, in 1896 when teenage brothers George (1878–1963) and Earl Holley built a small, one-cylinder, three-wheeled vehicle they dubbed the "Runabout", with a top speed of 30 mph.
