WebOverall reaction of photosynthesis. In chemical terms, photosynthesis is a light-energized oxidation -reduction process. (Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule.) In plant photosynthesis, the energy of light is used to drive the oxidation of water (H O), producing ... Web19 hours ago · Algae grown in transparent tanks or tubes supplied with carbon dioxide can convert the greenhouse gas into other compounds, such as food supplements or fuels. But the process leads to a buildup of algae on the surfaces that clouds them and reduces efficiency, requiring laborious cleanout procedures every couple of weeks.

Process for removal of sulfur dioxide from gaseous mixtures

WebThe removed compounds are recycled by one of three ways: (1) by subjecting them to carbon monoxide to obtain sulfur and ammonia, (2) by heating the materials in a vacuum to remove much of the sulfur dioxide, or (3) by volatilizing them and passing the vapors through a metal carbonate to obtain ammonia, carbon dioxide and a metal sulfite. WebFeb 24, 2024 · February 24, 2024. Scientists led by a team at Caltech have developed a new method for potentially removing nearly all sulfur compounds from gas and diesel fuel. Sulfur compounds in fuels such as gasoline and diesel create air pollution when the fuel is burned. To address that challenge, large-scale oil refinery processes remove the … tailby meadow

Webchemical reaction, it is not possible for a Claus plant to convert all the incoming sulfur compounds to elemental sulfur. Therefore, 2 or more stages are used in series to recover the sulfur. Each catalytic stage can recover half to two-thirds of the incoming sulfur. The number of catalytic stages depends upon the level of conversion desired.

"Hydrodesulfurization (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating … See more Although some reactions involving catalytic hydrogenation of organic substances were already known, the property of finely divided nickel to catalyze the fixation of hydrogen on hydrocarbon (ethylene See more Hydrogenation is a class of chemical reactions in which the net result is the addition of hydrogen (H). Hydrogenolysis is a type of hydrogenation and results in the cleavage of the C-X chemical bond, where C is a carbon atom and X is a sulfur (S), nitrogen See more The refinery HDS feedstocks (naphtha, kerosene, diesel oil, and heavier oils) contain a wide range of organic sulfur compounds, including See more The basic hydrogenolysis reaction has a number of uses other than hydrodesulfurization. Hydrodenitrogenation The hydrogenolysis reaction is also used to reduce the nitrogen content of a petroleum stream … See more In an industrial hydrodesulfurization unit, such as in a refinery, the hydrodesulfurization reaction takes place in a fixed-bed reactor at elevated temperatures ranging … See more The main HDS catalysts are based on molybdenum disulfide (MoS 2) together with smaller amounts of other metals.
