Zinc oxide (ZnO) is used as a pretreatment step to remove hydrogen sulfide (H 2 S) from natural gas following hydrogenation of any sulfur compounds prior to a methane reformer, which can poison the catalyst.
Zinc Oxide: An Essential Chemical Compound. Zinc Oxide, often referred to as ‘ZnO’, is a widely used compound known for its distinct properties and widespread applications. The compound, a white powder that is insoluble in water, is commonly found in mineral form as ‘zincite’.
Zinc oxide, ZnO, is one of the most important zinc compounds. It can be prepared in a state of high purity and in a variety of crystal shapes and sizes by burning zinc vapour in air.
15 Μαρ 2012 · Zinc oxide is produced mainly by three distinct processes: directly oxidizing zinc metal, or reduction of an ore to zinc metal followed by controlled re-oxidation or, to a far lesser extent, precipitation of the oxide or a carbonate from an aqueous solution followed by calcination.
23 Σεπ 2014 · Zinc oxide (ZnO) is a common inorganic compound with a large number of uses. It is insoluble in water but soluble in dilute acids and bases. Its melting point is extremely high—1975 ºC, where it also decomposes. ZnO exists in two common crystalline forms: wurtzite and zincblende.
A very important use is that Zinc Oxide is widely used as the buffer layer in CIGS (Copper Indium Gallium Selenide) solar cells. Some current experiments are focusing on the effect of the thickness of ZnO on maximum power output for the cells. Another main use in in concrete manufacture.
Basic Characteristic: Zinc oxide reacts with acids to form salts, underlining its basic property. Acidic Characteristic: It also reacts with strong alkalis to form zincates, demonstrating its acidic nature.
